PSAT-2 Telemetry
by Nicholas Mahr KE8AKW 26 Jun '19

26 Jun '19

Hi Bob, Heard PSAT-2 on a 7 degree pass. Unfortunately the highest passes are only about 7-8 degrees in elevation right now. However managed to snag this at 6/26/2019 at 04:55 and 04:56UTC. I will be listening for BRICSAT-2 next on 437.600 however chances of decoding it will be low due to the low elevation and the nature of 9600 baud. 1:Fm PSAT2-1 To APOFF Via ARISS <UI R Pid=F0 Len=34> [00:54:59R] [+++] T#294,685,074,921,925,162,01000001 1:Fm PSAT2-1 To APOFF Via ARISS <UI R Pid=F0 Len=34> [00:56:00R] [-++] T#295,684,061,924,927,162,01000001 73 Nick KE8AKW

25 Jun '19

Bob, thanks for the updates on PSAT2. The info on your website also lists BICSAT-2. And you provide info on that Sat on previous posts, but is BRICSAT-2 a separate Satellite launched last night? does it have the same TLEs as PSAT2? I didnt see it listed in the IARU, or I missed it. 73 Christy KB6LTY

Good afternoon, I have an individual who has approached me about working with him over the phone to help him set up SatPC32. Unfortunately, I do not use SatPC32 for antenna or radio control on a daily basis and am probably not the best person to help. If anyone is willing to help someone with SatPC32 via the phone, please let me know offline. Thanks! 73, Paul, N8HM

AI6DO Field Day Report
by Ryan Noguchi 25 Jun '19

25 Jun '19

Unlike last year, where I participated in ARRL and AMSAT Field Day concurrently, I did them separately this year. On Saturday, I worked only satellites for AMSAT Field Day from the vicinity of my home. I never operated from my property, only from other operating positions along my block each optimized for specific pass orientations, all well within an 800 ft circle. All QSOs were made fully pedestrian-mobile, without recharging any of the batteries during the Field Day period. Most of the FM satellites were a mess, as expected. The one daylight AO-92 L/v mode pass, 20 degrees to the west, was pretty empty, but gave me my first QSO of the day, with WD9EWK. I chose to dual-wield two antennas rather than attach the two together as I've normally done in the past. I strapped the DJ-G7T radio to the handle of the 10-element 23cm EBay yagi, where the PTT button and the VFO A knob were easily adjustable with just my left thumb; in my right hand, I held the Arrow. This worked pretty well, and I found it less fatiguing than having one heavier antenna. Also made QSOs on PO-101 and AO-85. AO-85 sounded really good, at least for that minute or so I was on. As soon as I got the QSO, I split to go work another pass. Tried LilacSat-2 twice, nothing heard. The SSB satellites seemed to have few operators on, other than QRO CW stations. On one FO-29 pass, there were two CW stations calling CQ nearly on top of each other and on top of a SSB station calling CQ, while most of the passband was empty. Worked several linear passes, but made only one QSO, and we really had to work for that one. The far-western XW-2 passes were pretty empty. The packet satellites were underutilized, and could have been a great source of points had more operators been on. Made several QSOs on FalconSat-3 and PSAT, although only one counts for AMSAT Field Day credit. Unfortunately, the ISS digipeater was offline. Worked a total of 20 passes, although for five of them the satellite was inoperative. Total of 6 qualifying QSOs, half of them with WD9EWK. I had planned to do several more passes that evening and a few more before sunrise the next morning, but I decided to put this day out of its misery and conserve my energy for Sunday. On Sunday morning, I drove to my portable operating location to operate the rest of the Field Day period for only ARRL Field Day. Since I was going to operate 2B1B for ARRL Field Day, I used the same operating category for my AMSAT Field Day contacts for consistency. For the first time, I made a full-time SO2R effort, with one radio dedicated to CW and the other dedicated to FT8. Didn't even try SSB. Also made one FM satellite contact after 1800z from that operating location for the 100 pt bonus and my sole phone contact for ARRL Field Day. So, how'd everyone else's Field Day go? 73, Ryan AI6DO

Correct up-link frequency for PO-101 (Diwata-2)
by Mac A. Cody 25 Jun '19

25 Jun '19

On the AMSAT FM Satellite Frequency Summary it lists the up-link frequency for PO-101 (Diwata-2) as 437.500 MHz. On the PHL Microsat website, the up-link frequency is listed as 437.7 MHz.?? Which is correct??? I tried to work PO-101 during Field Day yesterday and had no success getting in with my radio set to 437.500 MHz, and Doppler-shift adjusted near values.?? Of course, being Field Day, I could have just been 'out-gunned'. I do wonder, though. 73, Mac / AE5PH

2nd/backup FM HT recommendations
by Philip Jenkins 24 Jun '19

24 Jun '19

I'm considering buying another FM HT for the birds, mainly to use as a backup - for demos. (I already have a D72, which is my main unit for personal use and demos right now, and a VX7R, but the latter has seen better days.) For those of you who have attempted to use just a D72 for a demo - with an external speaker as well as the headset/mic - this results in a rat's nest of adapters/connectors/wires. I have the adapter sold on eBay, but unfortunately it attenuates the audio signal (for digital voice recorders), instead of amplifying it for an external speaker , which is what I need. (I guess I could use a powered speaker on that output, but that's one more thing to carry - and power-up! :-) ) So I think *two* radios might work better - wiring wise - for demos. If I buy a Baofeng (or similar), I won't use it for the receive part due to the desense problems on some models (looking at the section in 2019's "Getting Started with Amateur Satellites"). I'm considering the Alinco, since it does have 1.2 Ghz, and using the D72 for receive in that set up (but that still doesn't easily solve the wiring/connector mess for an external speaker/headphones for that radio). Are there other radios which are more "external speaker" friendly which I should consider? I'm open to almost any combination of manufacturers (except for the Baofeng types for receive, as noted above). I'm even open to buying another D72 (but probably hoarding it except for special occasions.) In short, what are your recommendations for a second, spare, radio for the FM birds? I'm also curious how others have wired their single HTs - or two HTs - for demos using an external speaker. So if you could explain - with or without pictures - how you accomplish this, I'd appreciate it. Thanks Philip N4HF

Icom 821h For Sale

Hey All, I'm selling my Icom 821h that I've used for the past 4 years to break all sorts of distance records and work all the grids out there. The rig still works amazingly well, and the only reason I'm parting with it is because I upgraded to a 9700, and it's just better. See my listing in the 'Zed forums here: https://forums.qrz.com/index.php?threads/icom-821h-all-mode-vhf-uhf-radio-f… I'd love to see this rig go to another AMSAT member and keep on getting used to work the birds for the rest of time.

Another first: rotor problems
by Hans BX2ABT 24 Jun '19

24 Jun '19

There is a first for everything. So today for the first time in my 10 years as an amateur radio operator I experienced that my KR-400 rotator (partially) stopped working. It has not been in use for 10 years, only the last 8 months and the motor was cleaned and greased before the install. Before I start dismantling everything I would like to see if any of you have any good advice. The problem --- it will turn right, not left. What I measured --- between terminals 5 and 6 (right turn) I measured 31 Volts, which is normal. Between 4 and 6 (left turn) only 21 Volts. Rotor not connected to the controlling box when measuring. My thoughts --- must be in the controlling box. However, there is simply nothing there in the circuit that I think could act up. From the transformer one terminal carrying 29 Volts goes to two switches. The other terminal is neutral. There is the light bulb between the two terminals and a 70 uF/50V capacitor between the two switches. I could be entirely wrong, so spill any info and/or tips that you can give me, here. Cheers, Hans BX2ABT

G5400B rotor problem
by Richard Lawn 23 Jun '19

23 Jun '19

I have an old 5400B that I use at a summer location. I use another old fox delta serial control interface that emulate GS-232. It has developed a strange problem with the AZ rotor that seems to occur when it reaches the extreme S (past E) where it tends to freeze. The only way to unfreeze it and gain control again is to shut the control box off for a short time and then it will run fine manually or under control by SATPC32. I’m guessing there may be some thermal device inside the rotor itself that is exceeding a limit and needs to cool down. I’d love to hear some suggestions on what the problem might be. Tnx Rick, W2JAZ -- Sent from Gmail Mobile

Re: [amsat-bb] Operating with the THD-72 handheld
by gw1fky＠aol.com 23 Jun '19

23 Jun '19

Hi,Regarding the problems of operating with the THD-72 ( or other portable ) and avoiding the tangle of wires etc.Patrick WD9EWK/VA7EWK mentioned that he has a "Bluetooth" speaker with a jack socket. It is much easier to obtain a a " Bluetooth" audio transmitter and thus avoid the need for any wires. These transmitters are reasonable cheap and available from a number of well known sources.Simply plug the Blue tooth Tx into THD-72 audio jack and pair with the Bluetooth speaker - You canadjust the THD-72 volume control to suit your conditions.The size of these Bluetooth transmitters is sometimes smaller than an SDR dongle, some even have a wired jack plug fitted. I have used this method not only for portable operation, but also for demonstrations, It made it much easier for those listening and myself of course."WIRELESS" Hi Hi. Ken EatonGW1FKY PS.The method can be used with many other radios etc and I have used it to set up my LNB/dish to monitor QO-100 down link/ beacons and operators. ( An AOR receiver on 739 Mhz SSB )

Leading up to the 2019 AMSAT 50th Anniversary Space Symposium and General Meeting, to be held in Arlington, VA, October 18 – 20, 2019, AMSAT’s call sign, W3ZM, will operate from all 50 States, the District of Columbia, and Puerto Rico. Not only is this your chance to get Worked All States-Satellites under the W3ZM call sign, but, also, your chance to be a part of this historic effort. Note: When operating outside of the “3” call area, operators will append the W3ZM call sign with “/(call area).” As an example, someone operating from Texas will use W3ZM/5; from Hawaii, W3ZM/KH6; from Alaska, W3ZM/KL7; and from Puerto Rico, W3ZM/WP4. To make this happen – We need your help! Please volunteer to get on the air and activate your State, using AMSAT’s W3ZM call sign, as well as to cover those States without an active AMSAT Member. Activations of other United States Territories (i.e. Guam, American Samoa, the U. S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands) are also welcome. To volunteer and operate using AMSAT’s W3ZM call sign, you must: Be a current member of AMSAT Obtain permission by emailing AMSAT VP of User Services, specifying the requested date(s) and location(s) Submit an ADIF log of contacts made for upload to LoTW by AMSAT, as instructed in your notice of approval to use the W3ZM call sign [ANS thanks Robert Bankston, KE4AL, AMSAT VP of User Services for the above information] --------------------------------------------------------------------- +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ 2019 marks AMSAT’s 50th Anniversary of Keeping Amateur Radio in Space.

This cubesat will be propelled solely by sunlight, to Earth orbit. LightSail 2 is scheduled to launch aboard a SpaceX Falcon Heavy on June 24, 2019, and we will attempt the first, controlled solar sail flight in Earth orbit. LightSail 2 will ride to space aboard the Department of Defense Space Test Program-2 (STP-2) mission which will send 24 spacecraft to 3 different orbits. LightSail 2 itself will be enclosed within Prox-1, a Georgia Tech-designed spacecraft originally built to demon- strate close-encounter operations with other spacecraft. Prox-1 will deploy LightSail 2 seven days after launch. After a few days of health and status checks, LightSail 2's four dual-sided solar panels will swing open. Roughly a day later, four metallic booms will unfurl four triangular Mylar sails from storage. The sails, which have a combined area of 32 square meters [344 square feet], will turn towards the sun for half of each orbit, giving the spacecraft a tiny push no stronger than the weight of a paperclip. For about a month after sail deployment, this continual thrust should raise LightSail 2's orbit by a measurable amount. LightSail 2 will fly in a 24-degree inclination, 720 km, circular orbit. At latitudes of 42 degrees north it will reach a maximum elevation of 10 degrees above the horizon. Lightsail-2 has been issued an experimental radio license WM9XPA and transmit on 437.025 MHz. A morse beacon will transmit the callsign every 45 seconds. A packet beacon will transmit AX.25, FSK 9K6 bps data.

During the June 17 event students in the program were provided with two opportunities to learn about space communications from widely different perspectives. The first session was led by Radio Amateur Satellite Corporation (AMSAT) president Joe Spier – the second by Dave Israel, the Exploration and Space Communications (ESC) projects division’s lead architect. With Spier, SCaN interns got the chance to learn about AMSAT, a volunteer organization that designs, builds, launches and commands amateur radio payloads on satellites. SCaN intern and “ham” Caitlyn Singam was required to pass a rigorous FCC exam to be given her unique callsign, AC3AG, at the highest level of certification, ‘Amateur Extra-class’. Given her history with amateur radio the talk was particularly inspiring. “I actually ended up talking to Mr. Spier afterwards about getting involved in AMSAT,” Singam said. “It was really exciting.” Singham enjoyed learning about Spier’s unconventional route to AMSAT, which she related to in her own academic career. “I’ve had an interesting route myself, with biological sciences and a master’s in systems [engineering] in the fall,” she said. Spier’s route took him from a background in geology to becoming a leader in the small satellite community. He had early dreams of becoming the first to climb Olympus Mons, the highest peak on Mars. Today, he refers to the interns as the ‘Mars generation,’ hoping that an intern today might summit that peak in the near future. He shared his personal strategy on making big NASA dreams come true: “I always clarified it by saying, ‘If I can’t be that person, I want to help someone else be that person.’” In the afternoon, SCaN interns met with ESC’s lead communications architect for an overview of division projects. Israel’s work at NASA spans 30 years. Interns heard about topics ranging from the development of Tracking and Data Relay Satellites (TDRS) in the late 1980s to the Space Mobile Network, a concept for an interplanetary internet that Israel envisions coming to fruition in the near future. Israel, like Spier, offered the SCaN interns in attendance some advice: “Never keep any good ideas to yourself, and don’t worry about asking questions from a different perspective,” Israel said. “A question from a different perspective gets people to think about it in a different sort of way.” "Never keep any good ideas to yourself, and don't worry about asking questions from a different perspective." Dave Israel, ESC Communications Architect To Grace McFassel, a SCaN intern who attended the talk, Israel’s story was not only interesting, but inspiring. “He [has] this specific skillset that he dearly loves, and he’s used that to carry himself through by finding niches where he can be useful,” McFassel said. “It’s a good lesson to carry forward.” To learn more about SIP or SCaN, visit NASA.gov/SCaN.

New release of G0KLA Tracker
by Chris Thompson 22 Jun '19

22 Jun '19

I have released version 1.01a of the G0KLA Satellite tracker. I had hoped to get it out further in advance of field day, but work pressures got in the way. Anyway for those of you in the US, here it is the day before :) This version has a few tweaks, most requested by users. * Key display settings can be changed on the main window from a set of icons bottom left. e.g. showing spacecraft in eclipse vs sun. * You can display horizontal lines for 30 and 60 degrees. * You can display horizontal lines for all labels on the vertical axis if you want * Time labels have a slightly more sensible gap between them, e.g. 15 mins, vs a random amount that fit in the window like 13 mins * Past mins can now be as short as 10 mins, though you can also specify a long period if you want The downloads are in the usual place here: http://www.g0kla.com/klatrack/KlaTrack_1.01a_windows.zip http://www.g0kla.com/klatrack/KlaTrack_1.01a_linux.tar.gz http://www.g0kla.com/klatrack/KlaTrack_1.01a_mac.tar.gz 73 Chris g0kla / ac2cz -- Chris E.

Doppler adjustment proper procedure question
by skristof＠etczone.com 21 Jun '19

21 Jun '19

On the official ARRL VHF/UHF info sheet (http://www.arrl.org/files/file/Field-Day/2019/2019%20Above%2030%20MHz%20-%2…) they suggest that for satellite QSOs operators should only adjust their receive frequency regardless of whether it is VHF or UHF. I thought standard procedure was to adjust the higher frequency whether it is transmit or receive. Steve AI9IN

M2 Leopack 2Meter swr
by Rafael Pena 20 Jun '19

20 Jun '19

Recently, I had my roof done and had to remove the M2 Leopack from the mast together with the G-5500 Az/El. I sat it on the roof floor next to my house. Now that I place it back, the 2M SWR is way high off the sat or regular 2m frequencies 440 is as expected. It is not coax since I tested it with a short piece and analyzer with same results. I had not check the coax stubs yet and thought to write hear first. Any hints will be appreciated. M2 website has a "Blog" which contains only info on Ohm meter testing. Rafael / NN3RP

Arrow 2 Antenna
by Kees van Oosbree 20 Jun '19

20 Jun '19

Hello there! I've been having trouble with my Arrow Antenna on the FOX sats. It seems that when I point my antenna at the satellite, say on a 70 degree max elevation pass, it doesn't receive it. But when I point the antenna at the ground, it comes in very clearly. Towards the end of the pass, I start receiving it again because I'm pointing my antenna near the horizon. At this time, I make all of my contacts. What could be the problem? I checked the elements on the antenna and they aren't mixed up. Thank you! 73 de KE0STO

Upcoming ARISS contact with Traverse Area District Library, Traverse City, MI
by n4csitwo＠bellsouth.net 20 Jun '19

20 Jun '19

An International Space Station school contact has been planned with participants at Traverse Area District Library, Traverse City, MI on 28 June. The event is scheduled to begin at approximately 14:02 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and W8TCM. The contact should be audible over the state of Michigan and areas within the ISS signal path. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. If you hold your right hand up, palm side facing you, that's what people from the lower peninsula of Michigan use as a reasonable map (just ask Astronaut Christina Koch). Traverse City is situated at the notch formed between your pinky and ring fingers, representing its location at the head of Grand Traverse Bay, part of Lake Michigan. Its location near the 45th parallel region and the Great lakes generally offers warm, mild, summers and severe winters. The Traverse City area is the largest producer of tart cherries in the United States, and each July the city hosts the weeklong National Cherry Festival attracting approximately 500,000 visitors annually. The surrounding countryside also produces hops and grapes, and is one of the centers of wine production in the Midwest. The area features many natural attractions, including freshwater beaches, Sleeping Bear Dunes National Lakeshore, downhill skiing areas, and numerous forests. Arts and cultural activities such as the Traverse City Film Festival, the National Writers Series, and nearby Interlochen Center for the Arts, add to a vibrant quality of life. The Traverse Area District Library (TADL) is a network of six libraries, serving over 90,000 residents of Grand Traverse County. With over 68,000 active cardholders, TADL provides dynamic resources and innovative services to stimulate intellectual curiosity, facilitate lifelong learning, promote literacy, and nurture personal enrichment. This includes many resources and programs to support early literacy. Encouraging exploration and curiosity through STEM and other creative programs for youth. TADL provides access to a variety of materials and services for research, local history collections, learning new or developing existing skills, and much more. Our annual Summer Reading Club program, for readers of all ages, is in full swing. This year's theme is about space and titled: A Universe of Stories. Participants will ask as many of the following questions as time allows: 1. What personal items did you bring with you to space? 2. What does math have to do with space? Do you use addition, multiplication or algebra? 3. What effect does being in space have on the body other than being taller? 4. Does low gravity interfere with your digestive system? 5. How will your new robot, Astrobee, help you work in space? 6. How do you make or store oxygen in space? 7. How do you prevent medical problems in space, and what happens if an astronaut requires emergency surgery? 8. How much space debris is in orbit, and how do you handle it when it comes near the ISS? 9. How many girls go up to outer space? 10. What responsibility and/or efforts is the space program making to protect the ozone layer? 11. How did your military background apply to becoming an astronaut? 12. What do you do with the trash on the ISS? Do you recycle or reuse? 13. Can you see the melting of glaciers and polar ice caps from outer space? 14. How is sleeping in space different from sleeping on Earth? 15. How long can you work in the space suit during a spacewalk? 16. What is your favorite food in space? PLEASE CHECK THE FOLLOWING FOR MORE INFORMATION ON ARISS UPDATES: Visit ARISS on Facebook. We can be found at Amateur Radio on the International Space Station (ARISS). To receive our Twitter updates, follow @ARISS_status Next planned event(s): TBD About ARISS Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

SDRSharp - HW Virtual Serial Port - UZ7HO's High Speed Soundmodem - Wisp problems
by Vincenzo Mone 19 Jun '19

19 Jun '19

Hi folks, I have been off from the satellite for a while due to the broken Funcube Dongle Pro Plus. I have ordered and received a coupe of days ago my new one but I cannot get it working Properly on the Falconsat-3 Bird. I explain the problem hoping in some help. I am using SDRSharp - HW Virtual Serial Port - UZ7HO's High Speed Soundmodem - Wisp When I receive the satellite I can see the data incoming in the UZ7HO's High Speed Soundmodem But I do not see nothing in the MSPE ( Wisp ). When I try to transmit I can see the radio going in TX and it remains in TX as locked and get the error form the UZ7HO's High Speed Soundmodem saying: Error opening wave output device (unspecified error). I cannot get in RX again so I need to reset the PC. Please anybody can explain me were am I doing wrong?

Satellite rise time/elevation app
by Richard Lawn 19 Jun '19

19 Jun '19

Some months ago someone told me about an app that I think was created by a UK ham. It is a great color timeline showing visual indications of when satellites rise and decline and their elevations for any location as set in the setup screen. The timeline also shows the time for each satellite rise based on the users location. Users can also decide which which satellites they want to include on the timeline. Various parameters like these are established in the setup screen. I’m now at my vacation QTH and for the life of me I can’t remember the name of this app and want to install it on my computer at the lake house. Can someone point me in the right direction.

by n4csitwo＠bellsouth.net 19 Jun '19

19 Jun '19

An International Space Station school contact has been planned with participants at Rowan Preparatory School, Claygate, United Kingdom on 20 June. The event is scheduled to begin at approximately 12:48 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and GB4RPS. The contact should be audible over the United Kingdom and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Story: Rowan Preparatory School is a vibrant, friendly and nurturing community where girls are encouraged to be themselves. Our school is an independent preparatory school for girls between the ages of 2 to 11, located in the heart of Claygate (near Esher) in Surrey. A school with traditional values and a forward thinking approach to education, we seek to offer a broad and adventurous curriculum full of exciting opportunities. School life at Rowan is inspiring and offers a breadth of experiences which develop the whole child. The warmth that is evident when you walk through the door at Rowan creates the ideal learning environment for girls to fulfil their potential. They are nurtured and allowed to grow as individuals, encouraged to take risks and have a go at new skills and interests which will enrich their lives. Science, Technology, Engineering and Maths are at the heart of the curriculum at Rowan. Girls make the most of our dedicated specialist teaching spaces and delight in practical learning opportunities in the Engineering and Technology suite. From 3D printers to our radio recording studio, the environment at Rowan is geared towards encouraging creative and exciting learning, ensuring that the girls explore, question and discover in every area of learning. We are passionate about bringing STEM subjects to life and encouraging the girls to see how these subjects translate into the world beyond school. Experiences which will foster successful and inspirational women of the future! Rowan girls are prepared for the transition to a wide range of successful day and boarding schools and we pride ourselves on finding the right senior school environment for each and every girl. A personalised approach to learning and outstanding pastoral care in our happy environment, ensures that every girl develops a genuine love of learning. Participants will ask as many of the following questions as time allows: 1. How did the International Space Station get built when it just balances in the air? 2. What are the challenges to growing food in space if astronauts are to stay in space for longer? 3. Does your digestion change because in space there is no gravity so your intestine will float in your body? 4. Of all the experiments that you have done in space, what has given the most surprising result or has been the most exciting? 5. If you spin a ball in the ISS will it keep spinning or will it stop, and if it stops, what stops it? 6. In the future, will it be possible that someone can spend their entire life in space and if so, would their life expectancy change? 7. If you do a handstand in space does your blood go to your head if there is no gravity? 8. Is there anything you could learn about how bacteria and viruses behave in space that could help us defeat infectious bugs around the Earth? 9. NASA have said that they will establish a permanent presence on the moon within the next decade, how will they do this and what is the most exciting benefit for human kind? 10. In all of your time spent on board the ISS, what is the most exciting and extraordinary thing that you have experienced? 11. What new information about space are you hoping to learn? 12. Can you escape from a black hole? 13. We have learnt that astronauts are very busy and work long hours. So when you have free time, what do you do for fun? 14. How do you get rid of rubbish in space? 15. What are you looking forward to the most in nature when you return? 16. Our teachers and parents tell us that having a balanced diet is important. Is your diet closely monitored or do you have freedom to choose what you eat? What is your favourite meal? 17. How do you sleep in space? 18. What kind of dangers might you experience in space? 19. What is the most beautiful thing you can see in space? 20. We have heard that some people don't believe that the Moon landing took place, what is the best evidence that we have to disprove this theory?

Falconsat-3 upload problem
by Hans BX2ABT 18 Jun '19

18 Jun '19

Up til now I have been successful in getting PacSatGroundStation (PSGS) to work on receive. You can go here if you want to see my setup: http://bx2abt.com/main/Falconsat-3 . I can hit FalconSat-3 with a directory request or file download request and get an immediate response and consequent downloads. Uploading is a different story, however. I have been able to get some messages uploaded, but it was more by chance. Right now if I want to upload I seem to get into a loop where PSGS keeps on sending out the same frame (I presume), then disconnects, after which the whole cycle starts over again. From the PSGS debugging info you can see that I am successful in logging into PFS3-12. My file gets a designated ID (1f14 in this case) and is ready to be received. Then it uploads what I presume is one frame (you can see this in Direwolf where the same chunk of data is send over and over again) after which possibly the reason why things don't work: "ER_BODY_CHECK received while uploading: /home/hans/PacSatGroundData/FalconSat-3/BX2ABT17.txt.out". The only mention of ER_BODY_CHECK I can find on the internet is that it is sent when the checksum on the file body fails. After that the whole sequence starts again, so the message never gets uploaded and out of the queue. Does this problem lie with FalconSat-3, Direwolf or PGSG, or somewhere else? Where is the checksum being made? This is my first forray into packet radio/PacSat, so I'm not an expert (yet). I don't want to make any (un)educated guesses, thus any help or hints are appreciated.

The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between OR4ISS and IK1SLD. The contact should be audible over Italy and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. King Island District High School is located in the Bass Strait off the North West Coast of Tasmania. We cater for approximately 210 students from Kinder to Year 10. Our school is at the heart of our community, we value each student and their family. We have been striving to create resilient, innovative lifelong learners; our school has been on a learning journey with Literacy and Numeracy as our core fundamentals. Our students have the opportunities for on-island and off-island camps from Year 3 and up, we participate in sporting events in mainland Tasmania, we have students from Kinder to Year 10 being able to access specialist Music and Art lessons. We are grateful to have a well resourced MDT room, Computer Lab, kitchen which has then eventuated into a school café 'The Rock Café', which offers café style lunches, drinks and monthly dinners to our community giving our students first-hand experience of hospitality. We are also in the process of building our own golf hole to fit in with the islands golfing influx of late. Participants will ask as many of the following questions as time allows: 1. Why did you become an astronaut? 2. What training do you need to be an astronaut to go to space and where did you do your training? 3. What sort of food do you eat and how do you determine your meal times in space? 4. What do you do in your spare time so you don't get bored while in space? 5. Does it get lonely in space? 6. How do you exercise in space? 7. How old is the International Space Station and do parts wear out in space like they do on earth? 8. What is your job on the ISS and how do you do it? 9. What are space worms and why are they so important in space? 10. How long does it take to orbit the earth? 11. Have you researched the black hole and if so, how big is it? 12. What kind of research do you do? 13. Do you have any advice for any of our students wishing to follow in your career path?

Fixed elevation - how many elements?
by Martin Cooper 17 Jun '19

17 Jun '19

I'm contemplating building a couple of yagis, possibly even crossed ones, and putting them up at fixed elevation (i.e. az-only rotator). What I'm unclear about is how many elements to consider. My location is really pretty dreadful for seeing sky. There's a big hill to the NE that restricts me to above 40 degrees in that direction. I'm in a single-storey house, with neighbouring two-storey houses to the NW, SW, and S. In between all that, there are other single-storey houses, and trees in most of the gaps between houses. I can't afford to put up a tower (and it could never get above the hill anyway), so I'm looking at not too much above my roofline. To at least get through the trees, I'd think more elements would be better. But more elements narrows the beam, and at fixed elevation, that, at some point, will restrict even further how much of the sky I can play with. I'm looking for thoughts on how many elements would be recommended, and how many would be too many, for a fixed elevation, both for VHF and UHF. Ultimately, I'd like to be able to get on the linears, so not limited to the FM sats. Any thoughts would be much appreciated. Thanks in advance. Martin. KD6YAM

Quads on the satellites
by John Geiger 17 Jun '19

17 Jun '19

Has anyone tried the Cubix dualband quad on the satellites? I am wondering (hoping) that it might have a better elevation pattern than my Cushcraft A270-10S dualband yagi does. On Mode B passes, the satellite has to get to a 25 degree elevation or more before I really have a good chance at getting into the FM satellites. It would be nice to have something that allowed for better success at the lower elevations also. 73 John W5TD (ex AF5CC)

HS10KING on QO-100
by Tanan Rangseeprom 17 Jun '19

17 Jun '19

Dear AMSAT member, To strengthen the relationship between Thai and Japanese amateur radio operators representatives of the JAMSAT group of Japan have travelled to Thailand to visit the satellite ground station HS0AJ and will operate from the Ground Station of the Radio Amateur Society of Thailand under the patronage of His Majesty the King (RAST). On the occasion of the coronation of His Majesty King Vajiralongkorn Bodindradebayavarangkun, HS10A (pronounced "Hotel Sierra-TEN-Alpha), as the 10th king to reign in the Chakri Dynasty, the National Broadcasting and Telecommunications Commission (NBTC), Thailand's regulator, has authorized the special callsign HS10KING (pronounced "Hotel Sierra-TEN-KING). There will be an opportunity to communicate with HS10KING using the QO-100 amateur radio satellite and low earth orbit (LEO) satellites that windows pass over Thailand by amateur radio stations which is similar to AMSAT Germany's use of the special callsign DL50AMSAT using the QO-100 satellite. RAST hence invites AMSAT amateur radio satellite operators to join in contacting the HS10KING special event station from June 22, 2019 at 10.00 UTC (17.00 Thailand time) until June 23, 2019 at 10.00 UTC (17.00 Thailand time) using SSB mode and DATV (333 - 250 KS) signals from the station HS10KING. Please be informed and let others know of this opportunity. Sincerely and with respect, de HS1JAN Tanan Rangseeprom Project Manager of JAISAT-1

AO-85 report from the 2019-06-16 - 0028 UTC pass
by John Brier 17 Jun '19

17 Jun '19

Hi, I made five QSOs on this 47 degree pass from FM05. I was using my Kenwood TM-V71 radio at 50 watts and an Alaskan Arrow II antenna with the last third boom section removed. I didn't hear the bird for the first couple minutes of the pass and couldn't get it to come on myself. Eventually it came on and I heard Clayton W5PFG not long after that so I assume he turned the transponder on. In the first half of the pass it was difficult to get a solid signal into the sat. Other stations had the same problems. Audio was sometimes really low, great other times, and distorted at times as well. The last part of the pass was not bad though. I was able to consistently get a signal into the bird, even at 10 or 5 watts. I had a conversation with Roy K3RLD about this as we were both having the same good luck. This reminded me of past AO-85 behavior where it is easier to get in in the last part of the pass. I was actually on top of a landfill park in my town so I had a perfect view of the horizon and was able to get in all the way to LOS, albeit with some picket fencing effects on the downlink. Stations contacted: W5PFG W5HRH N9XCO * N0RC K3RLD Also heard ???PML * This was Richard N9XCO's first sat QSO. He just finished setting up a IC-9700/G-5500/SatPC32 station One odd thing I noticed is at the end of the pass I believe I was at 145.970 MHz, 10 KHz down from the center frequency of 145.980. It looked so weird I did a double take and doubted I was really at that frequency. I don't know if the bird was off frequency or if it was something on my end. My audio recording is here: https://www.dropbox.com/s/j1xduj3had9gicm/2019-06-16_0028_UTC_AO-85_KG4AKV_… 73, John Brier KG4AKV

Recent rove by N6DNM in DN00/10, DN20/30, DN41/51, DM79, DM58/59, DM48/49 grids
by Dmitry Mizin 16 Jun '19

16 Jun '19

Hello, Thank You for chasing me on my recent trip from above grids and mostly gridlines. I have uploaded (and corrected some) all entries into LOTW. I am sure I still have made a few mistakes with entries - so, if you worked me between 20190606 and 20190615 when I was in those gridline(s) and do not see a LOTW confirmation - please let me know. There were two undecipherable entries in my audio recordings from DM58/59 and DM48/49 both on SO-50 - if you are one of them, please let me know and I will review my recordings again. Once confirmed - will upload corrected entries. Thank you all again! It was a blast as this was my first "big" trip doing those activations. There will be more coming soon. Dmitry Mizin, N6DNM

input power question
by mikflathead＠aol.com 16 Jun '19

16 Jun '19

I have completed my sat station but am having trouble hearing myself. I have checked cables and antenna ( M2) sat antenna. All seems well with low SWR. I can hear on the 2 meter downlink. How much power is needed on the UHF uplink? Hope to figure this out shortly. This is being done on the SSB sats. Thanks Mike WB8PFZ

During the ARISS Forum at the Hamvention, it was announced, that between now and June 17, that an anonymous donor will equally match one dollar for each dollar donated up to $10,000. Here is an excellent opportunity to get the most from your donations to the ARISS FundRazr. The FundRazr Project was initiated to raise $150,000 towards the ARISS Radio Upgrade on ISS. To date 100 contributors have donated $26,200 to the campaign, about 17% of the goal.

Both downlink and uplink frequencies are off freq- uency low and DUV telemetry is not active. Continued operations are not guaranteed after the full illumination period ends on June 19. Work it while you can! AO-92 will be available in both U/v and L/v for Field Day this year. The current plan is to command AO-92 to L/v on the 0416Z pass on June 22, the evening before Field Day. The 24 hour timer will then run to expiration, and the satellite will revert to Mode U/v for the remainder of Field Day weekend. The planned timing should provide for at least one accessible pass for the continental US in L/v before returning to U/v. If commanding to L/v on the 0416Z pass is not successful, we will reattempt Field Day morning. Please keep the uplink clear during commanding. Additionally, requests were made to the LilacSat-2, IO-86 and PO-101 command stations for special scheduling of these FM repeaters for Field Day. Please watch for these teams’ schedule announcements on Twitter and amsat-bb prior to Field Day weekend. Note that IO-86 is only accessible to those stations below about 30 degrees of latitude, but is a very strong repeater and easily worked to the local horizon. The FM repeaters on AO-91 and SO-50 are also expected to be available as normal during Field Day.

The following sets out the current IARU position on these proposals. A proposal from France to consider the band 144-146 MHz as a primary allocation to the Aeronautical Mobile service, as part of a broader consideration of the spectrum allocated to that service. The band 144-146 MHz is allocated globally to the amateur and amateur satellite services on a primary basis. This is one of the few primary allocations to the amateur service above 29.7 MHz and as such is an important and widely used part of the amateur spectrum with a vast installed base of users and operational satellite stations. IARU views with grave concern any proposal to include this band in the proposed study. It will be representing this view energetically in Regional Telecommunications Organisations and in ITU to seek to obtain assurances that the spectrum will remain a primary allocation for the amateur services. A proposal to study the amateur allocation in the 1240-1300 MHz ("23cm") band following reported cases of interference to the Galileo navigation system. IARU is aware of a handful of cases where interference to the Galileo E6 signal has been reported. In all cases these have been resolved by local action with the full cooperation of the amateur stations concerned. IARU does not want the amateur service to affect the operation of the Galileo system in any way. Joint studies have been carried out to assess the true vulnerability of the system and, based on these, IARU regards the proposal to initiate an Agenda item for WRC-23 as pre- mature. The IARU position is that proper technical assessment of the issues involved should be made in the relevant CEPT study group. Proper account needs to be taken of the operational characteristics of the amateur service in order to develop sensible and proportionate measures that will facilitate the continued utility of the band for amateur experimentation whilst respecting the primary status of the GNSS service. IARU is ready to cooperate fully in any studies and shares the objective of reaching a secure and permanent solution to the issues of sharing in this band. IARU asks its Member Societies to draw this information to the attention of their members, and to refrain at this time from making speculative public comments about the situation until further progress has been made in regulatory discussions. IARU is also ready to discuss this issue with other societies not in IARU membership.

Today's earlier press release stating the contact with Smithsonian Air and Space - Udvar-Hazy, Chantilly, VA will be heard along the east coast of the U.S. was incorrect. This contact is a telebridge being handled through W6SRJ in California, so the ISS ham audio will instead be available over California and areas within the signal path. Our apologizes for this oversight. Dave, AA4KN ARISS PR --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

I'd been contemplating using the SatNOGS database to do automated lookups of transmitter info for satellites (from code), but frankly the database seems to be a bit of a mess. For example, in the 'satellites' database, there are cases of the same satellite name mapping to multiple NORAD catalog ids, the 'names' field being used inconsistently (and even containing an essay about the satellite in one case), and so forth. Similarly, the 'transmitters' database also has issues. Is there a more reliable source that can be queried through an API? I know N2YO has an API, but it's focused on real-time tracking, and doesn't appear to include transmitter info (though the site's satellite pages do). Thanks! Martin. KD6YAM

by n4csitwo＠bellsouth.net 15 Jun '19

15 Jun '19

An International Space Station school contact has been planned with participants at Smithsonian Air and Space - Udvar-Hazy, Chantilly, VA on 15 June. The event is scheduled to begin at approximately 18:11 UTC. It is recommended that you start listening approximately 10 minutes before this time. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and W6SRJ. The contact should be audible over the east coast of the U.S. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. National Air and Space Museum - Steven F. Udvar-Hazy Center Innovations in Flight Family Day The theme of this program is to give museum visitors the opportunity to learn about the innovations in aircraft design and what it takes to become a pilot by talking with pilots about how they learned to fly, what they fly, and how they use their aircraft. The day is designed to inform visitors of the opportunities in both military and civilian aviation. Visitors have the opportunity to talk with a diversified group of pilots to see different types of aircraft. This year we are celebrating the 50th Anniversary of the Apollo Program. Participants will ask as many of the following questions as time allows: 1. What is your favorite thing to do in microgravity? 2. How important are the people in mission control? 3. What is a normal day look like? 4. What was the launch like? 5. What is your least favorite part of being in space? 6. Are there any animals on station? 7. Did you know you wanted to be an astronaut when you were a kid? 8. There is a NASA T-38 at this event, what was your biggest challenge in learning to fly? 9. Where are you now? 10. What is your favorite space food? 11. What happens if someone gets sick? 12. What is around you? 13. Do you have a degree in science? 14. What kind of exercise do you do? 15.

XW-2D /-vs-/ ISS (... and everyone else)
by Scott 14 Jun '19

14 Jun '19

Hey everybody. Just walked in this evening (14-June-2019) & happened to catch the ISS at decent elevation around 2230 UTC. The packet digipeater sounded great and I had a quick exchange of digipeated 'Message' packets with W4TBD who happens to be just on the other side of town. As the ISS tracked NW to SE, I stood by to see who else might be around. I keep the FM radio's squelch open & volume up a little to judge how the downlink packets are sounding. All of a sudden, there was a dead carrier on (or at least near) the 145.825 ISS packet downlink. Sounded like a neighbor keying up to mess with me - except for the fact that I don't have any neighbors. I quickly spun another radio to the area of 145.825 and set it to USB to see if I could recognize what that jamming carrier was. Turns out it wasn't a dead carrier at all, but a tone sweeping back and forth. Someone else needs to check me (since you can't ever be sure from a single observation), but from the SUBJECT line of this post you know that the offending tone appeared to be from XW-2D which was passing directly overhead at the same time. Here is a link to a screen shot of their orbits when this happened: https://www.qsl.net/k/k4kdr//images/iss-xw2d.png ... so, if this VERY strong 2-meter signal was in fact from XW-2D, you might want to keep track of where that satellite is located just as a point of reference. There have been previous posts about XW-2D's transponder not working correctly. If you have uplink or downlink trouble with anything that operates in the 145.800 - 145.900 range, this might be the cause if I'm guessing correctly. 73, -Scott, K4KDR

PO-101?
by skristof＠etczone.com 14 Jun '19

14 Jun '19

I'm curious about satellite PO-101. The IARU coordination page says the uplink is 437.5 MHz but the Microsat-Diwata webpage says the uplink is 437.7 MHz. Which one is correct? I don't see a lot of reports on the AMSAT Current Status page for PO-101. Is it working? Steve AI9IN

Antenna SWR question
by skristof＠etczone.com 13 Jun '19

13 Jun '19

I've been having trouble getting into the FM satellites lately. It's the same rig I've been using for a couple of years and I have not had problems before. I bought a digital meter to measure power out from the handhelds and to measure SWR on the antennas. According to the meter I'm getting 4.9 W out of the handhelds, which is expected. For SWR I've got values of 1.7 at 70 cm and 2.0 at 2 m. The antenna is an Arrow. Are those acceptable SWR values? Should I try to get them lower? Can you even adjust the tuning on an Arrow antenna?

I gota Dreamcatcher Data Radiowhen they where on sale for $49. I can confirm that you can replace the supplied USB WiFi NIC with the TP-Link TL-UE3000 USB Ethernet NIC. I have to use a Pringles can on the LNB to get a marginalsignal, SNR -12.5 to -14 dB. Every time it rains I have to readjustthe LNB. I have senta few test ARPS messages from N4MTT-2 via rf to a local i-gate. The messages then were seen on the down link via a text file. The Skylark operating system has a "Messages" application that displays the text file. APRS Link can display the history of the messages sent to OUTNET, https://aprs.link/app/aprs/stations/messages-OUTNET I noticed the messages I sent to OUTNET did not receive a REPLY ACK. There where duplicate messages on the down link from another SSID. I wanted to avoid sending duplicate messages. In Xastir I canceled the messages after the first message transmission.

AO-85 is still kicking...
by Andrew Glasbrenner 13 Jun '19

13 Jun '19

Mark, N8MH and I did some testing tonight on AO-85 as it is almost back in full sun. The transmitter and COR repeater came on, but not the telemetry/IHU. Repeater sounded good but stayed keyed without an uplink signal. We shut the transmitter back off since that was an unexpected state. We'll do some more testing tomorrow. 73, Drew KO4MA AMSAT VP Operations

DopplerPSK - No 1 kHz-autotracking radio
by Nicholas Mahr KE8AKW 13 Jun '19

13 Jun '19

Yes what Tom and Scott said is what I do and is the correct way of working NO-84. You cannot just tune the 10m uplink like you would a linear transponder with SatPc32. It will make the PSK31 signal on the transponder undecodeable. The only real way to work it is with Doppler PSK. My setup consists of a FT-847 on the 70cm downlink, with SatPC32 correcting the doppler on the downlink which by the way I have no issues with. Then I have my FT-950 doing the uplinking on 10m (I use the FT-847 for VHF/UHF/Sat Only and FT-950 for HF only). I use a homebrew dipole that is actually for 40/80m but it tunes up on 10 meters just fine and works well for the uplink on NO-84. I then use FLdigi to decode the PSK31 signals as FLDigi allows multi-decoding for PSK31 which allows me to decode multiple signals in the passband at once. And of course I use DopplerPSK for the generation and correction of the PSK31 signal. Hope this helps. Unfortunately there is not a lot of activity on the PSK31 transponder but I hope that changes with the upcoming launch with Psat-2. - Nick KE8AKW

by tjschuessler＠verizon.net 13 Jun '19

DopplerPSK is a great program for dealing with doppler shift on the 10 meter uplink. The point being made that Yes, all mode rigs can do very small tuning steps in VFO mode as can my FT847. If I were going to use that one rig for NO-84, even with SatPC32, I would turn the doppler correction for uplink "OFF" and only track the 435 downlink FM so I could hear the FM carrier throughout, but let doppler PSK adjust audio tone for doppler and that will nicely keep the PSK signal stable AT the Satellite, inside the 28.120 + 3Khz receive passband. The cool thing is that you can still use just an FM mobile rig to receive the FM downlink, and 5Khz steps will still work pretty much just fine.

Question. All FM-only rigs of course only do 5 KHz steps anyway. Are we finding that multi-mode rigs when placed in FM mode can actually step smaller under CAT control? If so, then we must point that out to users, since it will not work for PSK31 even in FM. Thanks for the reminder. If rigs do that, then I will add this to the PSAT web page. The advice to not use auto-radio tuning except for 5 KHz steps on the downlink. IE, not smaller steps. Bob, WB4APR -----Original Message----- From: AMSAT-BB <amsat-bb-bounces(a)amsat.org> On Behalf Of aflowers--- via AMSAT-BB Sent: Wednesday, June 12, 2019 10:58 PM To: amsat-bb(a)amsat.org; Scott <scott23192(a)gmail.com> Subject: Re: [amsat-bb] DopplerPSK Scott, Roy, Umesh, et al; Part of the problem with PSK31 is that it required the adjustment for changes in Doppler shift to be to be phase-continuous. I think the Doppler rate (delta-Doppler shift) at even 10m is too fast for most radios--what you often get with CAT control, even if you can update while transmitting, is PSK31 that jumps more than 31Hz per update, and that totally destroys the phase continuity required to tell a '1' from '0'. This was the "fun" problem that spurred me to take a swing at it over a summer vacation. When DopplerPSK applies "anti-doppler" on the transmitted signal, it does so at the baseband audio level. This works fine for 3Khz passbands on a 10m uplink, but if you want to do it with SSB transponders and VHF and UHF you'll need an SDR where you aren't limited by an IF filter. The same algorithm in DopplerPSK could be used on a complex signal in the SDR architecture, and it could work equally on TX and RX in the processing chain. To the accuracy of the orbital elements everyone uses, if everyone corrects their uplink and downlink properly there is no perceived frequency drift by anyone using the satellite. Just what you need for a GHz-range LEO with a narrow-band transponder, eh? Since the downlink of NO-84 is FM there is no Doppler shift in the baseband audio of the downlink--you hear what the satellite hears. If we get a mode-K satellite it might be worthwhile to do a baseband demodulator in a soundcard since the total change in Doppler shift will be small enough to fit in a conventional HF radio's IF passband in both directions. If the antiquated hosting site doesn't come back I'll get off my duff and find a "proper" place for it. It's nice to see people playing around with it. (Thanks for bridging the gap in the meantime, Peter.)

The work has been done. #2, if memory serves, some radios do not respond to CAT frequency adjustments when transmitting. In this mode, your uplink radio is transmitting non-stop for the entire ~10 minute pass. If you have a hardware/software setup that can only change RF frequency when in receive mode, that will never happen during an NO-84 pass. Lastly, like much satellite work, the uplink and downlink are two completely separate discussions in this mode. While the 10m uplink works extremely well with the DopplerPSK software and the HF radio of your choice, receiving & demodulating the PSK31 downlink can be done by any antenna/FM radio(or SDR), and computer combination of your liking.

Re: [amsat-bb] OUTERnet becomes OTHERnet (APRS geo feed)

I monitor the rtl-sdr.com blog and also snatched up one of the Othernet receivers when it went on sale (and it came with a cheap LNB). But, like JoAnne, I've been busy doing other things and haven't gotten around to digging it out of the "RF drawer" and getting it to work. If anybody needs one for tinkering, let me know. I'd rather it go to somebody who will use it than just being used as furniture ballast. --Roy K3RLD > The $49 price for the Dreamcatcher SDR-type receiver that OtherNet was > peddling says it is sold out.

NO84 in safe mode
by Nicholas Mahr KE8AKW 12 Jun '19

12 Jun '19

Hi Bob, Just listened to the 03:05 UTC NO-84 pass on 6-12-19. Glad to report the PSK31 transponder is acting normally again! Had a quick qso with Scott K4KDR and it sounded like its usual self again. Also heard many beacons on 145.825 and looks like most of them were picked up by the igate on findu. Glad to see NO-84 back to its somewhat usual self again. Im sure it will be a valuable asset to use on field day also. 73 - Nick KE8AKW

Upcoming ARISS contact with Peninsula Grammar, Melbourne, Australia
by n4csitwo＠bellsouth.net 11 Jun '19

11 Jun '19

An International Space Station school contact has been planned with participants at Peninsula Grammar, Melbourne, Australia on 13 June. The event is scheduled to begin at approximately 11:10 UTC. It is recommended that you start listening approximately 10 minutes before this time.The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and VK4KHZ. The contact should be audible over portions of Australia and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Peninsula Grammar is a day and boarding school for approximately 1400 students from three-year-old Kindergarten to Year 12. At Peninsula Grammar we see learning not just as a path to university and a career, but also as a path to wellbeing. The books we read, the science we absorb, the languages we learn, the artistic, sporting and musical skills we acquire are the tools that enable us to fulfil our potential. Participants will ask as many of the following questions as time allows: 1. Although you are in quarantine before going to space, if someone was to get sick or injured in space, is there always a qualified first aid person when it happens? 2. How long will it take to recover and will you miss the space station when you come down? 3. What is your favourite thing to do in space? 4. What was your first thought during lift off when you travelled to the space station? 5. What kind of science experiments are you doing? 6. Why did you choose to be an astronaut? 7. How do you use the Internet on board the space station? 8. When you were first selected to go to the ISS in 2013, were you thinking about how much your research might affect the future on Earth and did that help you cope with leaving your family behind, getting into a space craft with people you don't really know and possibly risking your life? 9. What training did you do to become an astronaut? 10. Have you ever had a major issue with any of the technology on board the space station? 11. What is currently being done to try to help your life in space become easier? 12. How has your understanding of the universe changed now that you have seen it from space? 13. What do you miss most about Earth? 14. Can you have baths or showers in space? 15. Did the air force help you with what you are doing in space now?

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

Launch weight (mass) of Phase 3-E (Express)?
by Nicholas Mahr KE8AKW 11 Jun '19

11 Jun '19

Hi Greg, That is hard to say exactly for sure as it actually has not been done yet. Maybe somebody else out there knows? I do know AO-10/13 was around 140kg at launch with fuel and is 90kg without fuel. So it would be significantly less as the fuel does weigh a lot (50kg?). Also a quick search shows that a 400N motor weights around 9.5 pounds, so minus that.Unfortunately that launch opportunity for the direct launch to a Molniya type orbit was scrapped. Hopefully AMSAT find some sort of a affordable launch opportunity for it here soon in the up coming years. It is difficult enough now a days just to get a 1-2kg cubesat into LEO unfortunately. 73 - Nick KE8AKW

NO84 in safe mode
by Nicholas Mahr KE8AKW 11 Jun '19

11 Jun '19

Hi Bob, Yes me and Scott K4KDR has observed this both with NO-84 the past few days. Here is a video Scott has on youtube of NO-84's 70cm PSK31 downlink acting crazy https://www.youtube.com/watch?v=8XqcUNJumSE . The 70cm downlink has been either a ticking carrier, not transmitting at all, or will transmit properly for a few seconds before going crazy again. I hope this is not the last we hear of the PSK31 transponder as I have really enjoyed it. The APRS downlink with the beacon telemetry has been observed by both me and him as either off completely or on for a limited a time. I hope to see NO-84's condition improve soon and to see the launch coming up in a few weeks of NO-84s replacement, PSAT-2 on the next Falcon Heavy Launch! 73 - Nick KE8AKW

OUTERnet becomes OTHERnet (APRS geo feed)
by Robert Bruninga 11 Jun '19

11 Jun '19

Since about 2 years ago, the APRS satellite ground station captures have been made available worldwide via three GEO satellites for reception anywhere on earth. But I recently found that the OUTERnet system has changed to a new GEO satellite constellation and no longer uses INMARSAT L band satellites but is now using a KA band downlink over the USA. And that they are now selling a new receiver kit for this satellite. Has anyone kept up with them? Here is my original WEB page but with the links changed from OUTnet to OTHERnet: http://aprs.org/othernet.html If anyone has one of their receivers or is receiving the downlink and/or wants to help me get my web page all cleaned up to what has changed over the last two years, let me know. This is a powerful capability. I hope we can keep it working. Bob, Wb4APR
