The NO-84 Digipeater on 145.825 Mhz is on as of 2019-02-16 22:14:55 UTC. Enjoy it while its on. The Digipeater will be on as the power budget permits I presume. http://www1.findu.com/cgi-bin/pcsat.cgi?absolute=1 73 Nick KE8AKW

NO-84 Digipeater Online

Also forget to mention don't forget about the PSK31 Transponder also. It is always on 24/7 as it is the primary mission. It is very easily worked with just a simple 10m Dipole/Vertical and a directional 70 cm satellite antenna so mostly anyone should be able to work it. It downlinks on 435.350 FM and you uplink on 28.120 USB PSK31. You then use a program like FLdigi to decode the downlink as FLdigi has the ability to decode multiple PSK31 signals. Most importantly you must download a program called DopplerPSK as this is what you will be transmitting with. It automatically corrects the doppler on your uplink signal so others are able to decode your signal, otherwise it will just be a giant slant across the waterfall unable to be decoded. Currently there is only a small hand full of people working it. I would like to see more activity on it as it is good fun to work! 73 Nick KE8AKW

Joe, As far as I am aware NO-84 is just fine. Its just that it cannot always support having the Digipeater on 24/7 (It depends on battery conditions and amount of time in sunlight). So the digipeater is commanded on as it permits by the control operators. The PSK31 transponder is always on regardless of conditions. Hope to see you on PSK31!

TH D72, Heil HTH-K, and recording Qs
by K5ZM 17 Feb '19

17 Feb '19

Hi all. After having been licensed since '75, I'm finally dusting off my interest in sat work! I've got a Kenwood D72 paired with a short Arrow II. I also picked up a Heil boom mic HT headset for the Kenwood HTs -but now wonder if that part will actually end up complicating my efforts to record my Qs. The connector on the end of the headset is a two-pronged arrangement (think 'mini eggbeater') that uses both mic and speaker connections on the side of the D72. If I want to go forward with this headset, it's obvious I'll need to either fab something up or acquire a specialized patch cord, a Y cable, etc. If it comes to it, I can live without the headset and just use headphones in the event that makes life easier. Would like to hear what other ops are doing in this regard. Tnx es 73 Ian, K5ZM

A new 400bps telemetry beacon now on!
by Graham Shirville 16 Feb '19

16 Feb '19

Those of a certain vintage will remember listening to the distinctive 400 bps beacons from AO10, 13 and finally AO40. You can now hear the sound again, live. If you are in range of Oscar-100 then tune to 10489.800 MHz or, if not, then logon to the BATC/AMSAT-UK websdr here https://eshail.batc.org.uk/nb/and tune to the same frequency! Wonderful...thank you QARS and AMSAT-DL 73 Graham G3VZV

ARISS SSTV--This Weekend
by ka3hdo＠gmail.com 15 Feb '19

15 Feb '19

All, The ARISS team expects that a second SSTV transmission event will occur from ISS this weekend. ARISS Russia team member Sergey Samburov, RV3DR, worked with the mission control center flight controllers to schedule in ISS crew member time to configure the JVC Kenwood radio to support SSTV operations in the Service Module. SSTV setup is expected to start around 8:45 UTC on February 15 and conclude around 17:25 UTC on February 17. These dates/times are expectations and may vary. The ARISS team wanted to give the community another opportunity to downlink the SSTV images we developed for you given the weak signal situation that occurred last weekend. For clarity, these will be the same 12 images that were downlinked last weekend. As a reminder, you can get the latest SSTV information on the ARISS SSTV Blog Spot: <http://ariss-sstv.blogspot.com/> http://ariss-sstv.blogspot.com/ Once received, Images can be posted and viewed by the public at <http://www.spaceflightsoftware.com/ARISS_SSTV/index.php> http://www.spaceflightsoftware.com/ARISS_SSTV/index.php And you can receive a special SSTV ARISS Award for posting your image. See <https://ariss.pzk.org.pl/sstv/> https://ariss.pzk.org.pl/sstv/. For simplicity, we have added a new tab for SSTV, under general contacts, on the ARISS web site <http://www.ariss.org> www.ariss.org For those that are asking, we are still not totally clear what caused the issue last weekend. We believe it may have been either a loose feedline cable or an antenna switch that did not fully engage. Once the crew reset the system and checked the cabling and switches, the radio system started to perform nominally. Enjoy!! 73, Frank, KA3HDO *************************************** Frank H.

IC-910 SatPC 32 Doppler
by Greg 15 Feb '19

15 Feb '19

I am having trouble getting my TX frequency control using CAT. When I first turn on CAT, the frequency’s that are listed for a particular SSB sat do transfer to the radio (downlink and uplink). When I use the CAT to adjust TX frequency, nothing happens. When I use the CAT to adjust the receive frequency, the radio does change to the new frequency. However, there is no corresponding TX change. Feel like I’m a step away but can’t get it. Is it the labeling of a VFO in my uplink on the radio itself? Feel free to contact me off board in case this is a duplicate post that I missed over recent weeks. Greg N3MVF

SATPC32 - Is there a way to adjust downlink only?
by Bob 15 Feb '19

15 Feb '19

Hi, I'm using an Icom IC-9100 and the RIT control is almost useless as it changes frequency very slowly. To change 1 KHz takes about 15 seconds, a lifetime on a pass. In other words if a station calls me and they are a KHz off, then they will be off the air before I can get the RIT set. I'm running SatPC32 v 12.8d. The manual implies that there are Downlink adjustments when the V+ mode is turned on, but I only see uplink adjustments to the right of the frequency display that can either be moused up/down, or respond to the +/- keys. Perhaps there is something else that would open Downlink adjustment to the left of the display? Or maybe other keys that adjust the Downlink? 73, Bob, WB4SON

Re: [amsat-bb] amsat-bb] dual dish feed for Oscar100?
by Edward R Cole 15 Feb '19

15 Feb '19

Gabriel, I do not know if available in EU, but I used an 86cm offset feed dish originally used for Ku-band satellite TV here in the US for receiving AO-40 2.4 GHz telemetry. It used a six turn helical feed and db6nt preamp to Drake downconverter to 123 MHz IF (FT-847). I use a 60cm offset feed dish, commonly used in the lower-48 states of the US for satellite TV for my 10-GHz station. Feed is W1GHZ linear pol feed with corrugated horn. Most likely you will need a CP feed for Oscar-100. http://www.kl7uw.com/Another_Dish_Tripod.pdf Many eme'rs are having success on 10-GHz with as small at 60cm though 1m is better (for eme). I suspect Oscar-100 signals are much stronger than eme.

Doppler correction TM-V71A
by Ron VE8RT 14 Feb '19

14 Feb '19

Before commiting to a new TM-V71A, as it does not have CAT control is there a way to do Doppler correction other than manually selecting pre-programmed memory channels? In other words would it be possible to computer control the frequency from Gpredict or the Fox Telemetry software? Ron VE8RT -- Ron VE8RT <ve8rt(a)yknwt.ca>

Digi modes on Oscar100
by charlie＠sucklingfamily.free-online.co.uk 14 Feb '19

14 Feb '19

Hi All There has been some digital activity today on Oscar 100. I had to change uplink LO yesterday to a non-locked crystal controlled source, which has some small drift. This is making it impossible for me to use narrow tone spacing modes such as FT8 and JT65A. During a QSO with OZ1CTZ we were struggling with him decoding me on JT65A and he switched to JT65C after which the QSO proceeded perfectly. My drift problem on transmit is probably similar to that which would be experienced by unlocked Octagon users, so choosing a digi mode that is more immune to drift seems desirable. I did some testing here earlier using the Goonhilly SDR to feed audio to WSJT-X on a second PC and found also that JT9F (Fast) works extremely well with 100% reliable decoding. I've been testing with 10s periods mainly, but 5s also works. With these faster modes, drift will have less effect. JT9F is available in WSJT-X and needs to be run with VHF and up features enabled to access the 'Fast' checkbox. For JT65 users, I would recommend WSJT-X v2 over earlier releases, as the JT65 decoder was improved recently to cope with larger drift rates. If anyone is interested in trying this out, pse PM me and would be very happy to try it. 73 Charlie G3WDG

The Space Race is On--and We're Behind...
by Les Rayburn 13 Feb '19

13 Feb '19

:-) After listening to the WebSDR of Oscar-100 for nearly 24 hours now, it’s easy to imagine how my parents must have felt on October 4, 1957 as Sputnik transmitted it’s “beep beep beep” message to the world. Everything had changed in an instant. A geostationary hamsat is a quantum leap forward—and I confess to feeling a twinge of disappointment that someone other than AMSAT-NA accomplished this feat first. As a teenager, I remember driving a friends brand new, 1974 Corvette Stingray. My first thought was “Man! I gotta get me one of these!” Color me jealous. 73, Les Rayburn, N1LF Maylene, AL EM63nf AMSAT #38965, ARRL Life Member, CVHS Life Member, SVHF Member

Setting up the D72 for ISS packet?
by Robert Bruninga 13 Feb '19

13 Feb '19

Setting up the TH-D72 for ISS packet: Choose the APRS menu and set your CALLSIGN on the BASIC SET menu. Tune the radio BAND A to 145.825 with a good antenna and minimal coax loss. Turn on the TNC by pressing the TNC key to bring up the little tiny APRS12 lettering in the top of the screen. That’s all y ou need to start receiving ISS APRS packets. (I think) To transmit, you need to turn on your GPS **or** turn it off and manually enter your position using the POS key. Then when you want to transmit, hit the BCON key twice. Everyone, Did I miss anything in this minimal summary? Bob, WB4APR *From:* Gerald *Subject:* Re: [amsat-bb] ISS APRS Signal Quality? (tone skew?) corrected Bob, I have the Kenwood TH-D72A that comes with TNC, but have no idea how to use it. Even the manual is some what vague. Is there anyone on this site that may be able to help me with it? The HT has over 500 menus and I'm still trying to learn all of them. Thanks, Jerry...

Re: [amsat-bb] ISS APRS Signal Quality?
by Matt Hornsby 13 Feb '19

13 Feb '19

Just wanted to add to the dogpile about ISS APRS signal quality. Myself and others have noticed here in the Seattle area the same deafness since APRS came back online. We've tried on different th-d74s with arrow and elk antennas. I used to be able to reliably hit ISS on 5W with that setup. We've now seen that pumping 45 or 50 watts into one of those directional antennas is relatively successful, but 5W almost never works. Also, in the past, I've had no problem with my kenwood tm-d710 connected to a roof-mounted comet gp-3. 50 watts reliably worked to get digipeated at relatively low passes. Now, not so much. 73, Matt KS9O

ISS APRS Signal Quality?
by Frank Karnauskas 13 Feb '19

Is it me or does the APRS signal not sound as strong as it was before and is it not hearing quite as well? I am having a heck of a time pinging the digipeater and the signal seems to be down a bit. Could entirely be something on my end, but I would appreciate others' opinion. 73, Frank FRANK W. KARNAUSKAS, N1UW N1UW(a)GOKARNS.com

Re: [amsat-bb] ISS APRS Signal Quality? (tone skew?) corrected
by Robert Bruninga 13 Feb '19

Corrected email: I guess the fact that it is the same radio and just a new replacement TNC means that things should mostly be the same. But then again, nothing is ever exactly the same. Just the slightest difference in audio tone levels out of the new TNC could make a slight difference and for those who may have been on the good side of the "edge" might just get bumped over to the bad side of the edge. It was only a theory. Thanks to DAVE for clarifying what is new... Back under my rock...

WD9EWK @ DM31 tomorrow (14 February)...
by Patrick STODDARD (WD9EWK/VA7EWK) 13 Feb '19

13 Feb '19

Hi! On my way to the Yuma Hamfest which starts on Friday, I will make a detour to grid DM31 in southern Arizona once again tomorrow. I am only planning to work 4 passes from there: two on AO-92 (1647 & 1821 UTC), and two more on AO-91 (1800 & 1933 UTC). These 4 passes cover the continental USA, for those who may have missed my day-long trip to DM31 a couple of weekends ago. I am also hoping to pick up some new grids, so I can obtain a satellite VUCC award for operating from the Organ Pipe Cactus National Monument area (basically grids DM31 and DM32 in Arizona's Pima County). I currently have confirmed contacts with 99 different grids, from my trips to the national monument over the past 9+ years (25 of those came from my most-recent trip on 2 February). All QSOs made from DM31 tomorrow will be uploaded to Logbook of the World. If you would like a QSL card to confirm a contact with WD9EWK, please e-mail me directly with the QSO details. No need to first send me a card or SASE to get my card. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ Twitter: @WD9EWK or http://twitter.com/WD9EWK

I'm wondering if this might be a novel way of getting more utility out of it. I think it may even be possible in the Fox-Delta and G-Predict to increase these limits more. Obviously coax management must be considered. ---Roy K3RLD

The Space Race is On--and We're Behind...
by Nicholas Mahr KE8AKW 13 Feb '19

13 Feb '19

You guys do know AMSAT NA is going to be putting up our own geostationary satellite at some point right? From amsat.org about P4B: Virginia Tech continues to investigate opportunities to fly an amateur payload aboard a geostationary or geosynchronous satellite. A Payload Accommodation Study showed that an amateur payload could be carried on a U. S. Government satellite, but that satellite has been delayed indefinitely. Virginia Tech expects to have a further status update by summer 2018. So I'd say it's a matter of time before that happens. Be patient and I'm sure it will happen soon as well. As for P3E (Molyina orbit sat like AO-10/13) In July 2015, Virginia Tech approached the U. S. Government with a proposal to fly AMSAT-DL’s Phase 3E satellite spaceframe with both a scientific payload for the Government and an amateur radio payload to a Highly Elliptical Orbit (HEO). Under this proposal, AMSAT would have operated the amateur radio payload on the mission. Although the U. S. Government approved the proposal to fly Phase 3E on a classified flight, the Government required Virginia Tech to partner with a contractor in order to ensure on-time integration of the payload. Fulfilling this requirement would have caused the project to exceed the allocated budget by several million dollars which resulted in its cancellation. The Phase 3E satellite spaceframe remains in storage in Germany. Hopefully soon we get more information on P4B status, possibly at Dayton this year? At the end of the day we are held at the mercy of launch costs/payload providers. Nick, KE8AKE

DXCC Via Oscar-100
by Les Rayburn 12 Feb '19

12 Feb '19

Listening to the WebSDR link all morning. Very interesting to hear so many QSO’s, and in a variety of languages. I’m curious if DXCC will be a possibility using only this satellite? Looks like its footprint covers enough countries to qualify, but I’m not sure how many of those have amateur allocations that will allow operation on the bird. I’m sure it won’t be long until operators are “working the edges” of the footprint, and also mounting DX-expeditions to areas with few operators. Exciting stuff. I’d love to see a similar bird launched in this hemisphere. Opens up so many possibilities. Congratulations to all involved. One hundred amateur satellites, quite an achievement. And fitting that it should occur during the 50th anniversary of AMSAT. 73, Les Rayburn, N1LF Maylene, AL EM63nf AMSAT #38965, ARRL Life Member, CVHS Life Member, SVHF Member

Grid square entries
by Dr. Robert Keating 12 Feb '19

12 Feb '19

In light of the roving expeditions to rare grid squares this past weekend, I wanted to verify how these grid squares are entered into our logs on LoTW. >From what I remember, when setting up a station in TQSL you have the opportunity to create different station locations along with the grid square for each location. Is this correct? I want to be sure I have this right because I am heading out to Arches, Canyonlands and Capitol Reef National Parks in April and I will be operating on the FM birds from there. Thanks. 73, Bob N6REK

Upcoming ARISS contact with Faith Christian Academy, Orlando, FL
by n4csitwo＠bellsouth.net 11 Feb '19

11 Feb '19

An International Space Station school contact has been planned with participants at Faith Christian Academy, Orlando, FL on 14 Feb. The event is scheduled to begin at approximately 14:30 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and W9DWJ. The contact should be audible over Florida and portions of the eastern U.S. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Story: Faith Christian Academy is a private school located in Orange County in Orlando, FL. With a student body population of nearly 700, we teach grades K-12. We offer an array of subjects and electives during and after school hours. In addition to traditional athletic activities, we have an emphasis in the arts and have intentionally developed our STEM program in recent years. FCA leadership understands the diversity of the students that attend and therefore strives to prepare them for any future endeavors that suit their individual goals, personalities, and learning styles. Over 50 teachers instruct our students to understand their purpose and to work toward it from an early age. We believe in equipping children to become well rounded adults that are educated, caring, and ambitious. In preparation for the upcoming ARISS event, our school has done many things to bolster excitement about the ISS and space exploration in general. The students received credit for spotting and videoing the ISS as it passed overhead at night. In addition, they filled out ISS activity books provided on the NASA website, did Math projects on the distances between planets, painted pictures of the themselves with galactic themes in Art, took field trips to Kennedy Space Center, and were taught from curriculum that emphasized the International Space Station and the anticipated mission to Mars. In the weeks to come, we will have a team from a nearby amateur radio Club come to teach the students about Ham radio and Morse code. Also, FCA will hold after school classes for students to create a Raspberry Pi device in order to track the ISS and keep up with the current crew. Participants will ask as many of the following questions as time allows: 1. What advice would you give new astronauts preparing to join the ISS? 2. What are the mental and physical effects of going from Earth to space and back to Earth? 3. What is your favorite exercise to do in space and why? 4. Do all of you rotate jobs on the ISS? 5. How do you shave or cut your hair on the ISS without the hair floating away? 6. Do you have a certain pre-flight ritual? 7. Can you see any constellations while on the ISS and do you have a favorite one? 8. Have you ever experienced a major malfunction on the ISS? 9. Do your ears pop like they would when you fly in a plane? 10. Does everything in your body work the same in a microgravity environment, for instance, does your heart work harder to pump blood through the body? 11. Are you recognized as an astronaut on the streets? 12. Are you allowed to request certain things to be delivered by the cargo missions? 13. Describe the escape system on the ISS in case of an emergency. 14. What would you say has been your most important or meaningful experience in space? 15. What is the temperature inside the ISS vs outside the ISS? 16. Is there wi-fi on the space station? 17. Where is the garbage stored on the ISS? 18. What experiment are you currently working on and is it going well? 19. Is there ever a time when you feel a sense of panic on the ISS? 20. What did you feel the first time you saw Earth from the ISS? 21. How long does it take for your body to feel "normal" once you are in space? 22. What time zone do you work with on the ISS? 23. How many gallons of rocket fuel does it take to get to the International Space Station? 24. How do you keep up with current events happening on Earth?

Es'Hail 2
by Jean Marc Momple 11 Feb '19

11 Feb '19

Dear All, I just want to share that I copied many NB transmissions on Es’Hail 2 today clean and strong (a few callsigns well noted), however I believed that the HAM’s transmitting through the bird now are not very disciplined and not having at heart the interest of the community at large and acting irresponsibly. AMSAT-DL through many communication channels have requested that we should not do so before the official launch date, good reason for this is that it enable testing but also enable the sponsors to announce this officially and take credit to have offered this facility to the HAM community. If we act lightly we may not find many sponsors in the future. I therefore appeal to the community to abide with the set plan of AMSAT-DL not to jeopardize the future and further opportunities. Therefore guys keep away from Es’Hail 2 Tx for a few days so that you may enjoy same for the 15 next years, more show that as a community we are disciplined and organized. Hope this message will be heard for the benefit of all. 73 Jean Marc (3B8DU)

Logging QSOs on QRZ.com
by Bob Keating 11 Feb '19

11 Feb '19

Greeting All, First of all, my hat is off to Casey KI7UNJ and Jonathan KI7BEX for freezing their tails off in order to bring us a bunch of rare grids from BLM land in Nevada, thanks guys!!! Dmitri N6DNM emailed me that he couldn't confirm our satellite QSO on QRZ, even though all the data seemed to be correct. I have noticed this as well, that none of my satellite QSOs have been confirmed on QRZ either. We both uploaded our contact information via TQSL, filling all the information including transmit and receive bands and frequencies and then loaded it up to LoTW. I also use the specific frequency at the middle of the passband, for example, 435.350 and 145.880 for AO-92. I also save the adif file, naming it for the specific satellite and then upload it to QRZ.com and my HRD logbook. Why aren't my satellite QSOs getting confirmed on QRZ? Thanks for your help. 73 Bob N6REK

ISS reception (WIDE1-1 no-no) - APRS Gospel

It is not responding, but it is generating a Beacon from Bhutan-1: >> 1:Fm BIRDBT To APTT4 Via WIDE1-1 <UI R Pid=F0 Len=50> >> [16:28:38R] [-++] HELLO! THIS IS APRS-DIGIPEATER OF BHUTAN-1 CUBESAT My APRS recommendation for ALL APRS satellites since 2001 is that they should support these three aliases: Via ARISS - (for backward compatibility with ARISS users) Via APRSAT - (for ALL APRS satellites) Via WIDEn-N - (for those that forget to switch from Terrestrial mode) And, that simple periodic health telemetry from such satellites may be sent "via APRSAT" so that they can be heard beyond the horizon if there is another APRS satellite that is closer. Sending these spacecraft packets via WIDE1-1 is not good for the channel. It has the potential to generate footprint QRM anywhere in the world where a user may have their radios set to also be a fill in digipeater when used terrestrially. Such radios will key up on receipt of this packet and block the satellite for a full packet period. Thus reducing user throughput. All it takes is for one person in the whole country to have his rig set for fill-in digi, and this ueless extra WIDE1-1 will add this useless QRM on the uplink over that entire footprint. And no one except someone living within a few miles of this mistake will ever be able to detect it. Though it impacts everyone. I was certain I had published these settings as APRS SPACE GOSPEL, but just now I looked over all my aprs satellite p[ages and cannot find it anywhere except in the detail settings for each of my satellites. I'm sure it is in an AMSAT paper somewhere... Bob

MarconISSta spectrum analyzer experiment results
by Scott 10 Feb '19

10 Feb '19

Hello everyone. Sometime around 5-Feb-2019, there was an appeal from the Project Team running the MarconISSta spectrum analyzer experiment on the ISS for Amateurs to transmit on 70cm when the ISS was visible. The reason for this was because apparently the experiment was going to be powered off in just a few days. https://marconissta.com/2019/02/05/urgent-call-all-power-to-the-iss/ Along with a lot of other folks world-wide, I chose a frequency not "claimed" by anyone else nor close to other cubesats & transmitted a constant tone (FM) with a periodic 1200 baud packet ID through several passes of the ISS during the period requested. Thanks to a tweet from IW1DTU (I believe correct call sign), https://twitter.com/supertrack_it/status/1094665078853562369 ... I was alerted to the fact that there were result graphs online from the MarconISSta project. https://marconissta.com/2019/02/08/all-power-to-the-iss-first-results/ Using the dates, times, & frequency that I had transmitted, I'm pretty sure that I found myself on a couple of the waterfall graphs. Nothing surprising or particularly unique here, but I thought it was pretty neat to match up my transmission to their results. Here is a tweet I posted on this with an image showing "me". https://twitter.com/scott23192/status/1094681761458597889 73, -Scott, K4KDR

Attempting to set up ISS voice frequencies on a Yaesu FT-847 using OmniRig CAT control. Enter 145.800 FM for RX and 144.490 FM for TX. Rig recognizes frequencies when ISS is selected, and tracks for doppler. When I push PTT, I get "ERROR" on the TX Frequency. Any thoughts on how to correct the problem? Loon NA1SA

Dopler Adjust in IC-7100
by lu9cbl＠gmail.com 10 Feb '19

10 Feb '19

Hi to all! In my groundstation, i'm have orbitron to track the satellite, and WISPDDE to interact with the rotor (Yaesu) and the transceiver (IC7100). Reading the WispDDE software (from the source code that it's publicly available), we use the template of IC-910 to command the equipment, but acctually have a problem when we try to adjust dopler correction via USB, for both VFOs. Aparently to adjust the frequency of the VFOB, need first to put this VFO in the MAIN VFO. It's there any way to adjust the frecuency via USB, for BOTH VFOs (A and B), but mantain the MAIN VFO only for the VFO A? i cant find any information in the equipment manual. Thanks in advance.

Has anyone experienced problems with the Elevation or Azimuth indicator (meter) of G-5500 rotator ? The Elevation meter does not move at all. The LVB Tracker shows correct Azimuth and Elevation angles and the G-5500 rotator follows the correct angles. However, the Elevation meter of G-5500 remains at zero degree. The Azimuth meter works just fine. Thanks. 73, George N3GS

rotor feedback please?
by David J. Schmocker 10 Feb '19

10 Feb '19

Hello everyone: Has anyone direct experience using ProSistel PST-RR-55D ring or Creative Design ERC-51D or ERC-5AD (DC motor if there is one of these available)? with satellite antennas specifically a WiMo WX-220 2m RHCP cross-polarity yagi 4.3kG and 4.7m long boom, and also Helix 70cm per G3RUH design 16 Turns, 4.0 kG 2.8m boom length. These will be on a standard cross-boom of fiberglass tube which is 0.250 inch wall 2 inch OD). Please share good or bad rotator experiences. My personal requirement is to build major over-design capability into rotators because my experience (in the upper midwest) includes ice, snow, winds and I don¹t climb so I must rely on hired help for repairs. What has been your direct experience with these ProSistel and/or Creative Design rotors please? Thank you Very 73, Dave KJ9I

SSTV suggestion
by Greg D 09 Feb '19

09 Feb '19

Hi folks, A quick suggestion for future SSTV events... I notice that with the 12 images sequence, and current orbit times, every pass tends to have the same images come up. I recorded several passes today, and have several full or partial copies of the same images (7, 8, and 10). Could we add or remove a few images so that the sequence is different each time the Station comes around? Probably easier than implementing a randomization routine, unless that's already present. Thanks, Greg KO6TH

Re US IC-9700 prices announced
by David G0MRF 09 Feb '19

09 Feb '19

Hi Alan. Seems on par with the UK. Here in the UK the price is £1795. (probably the maximum they can get away with at the moment) To compare that figure you need to remove our outrageous local 20% tax. which is about £1496 + 20% So allowing about $1.30 to the UK Pound gives a US equivalent price of $1945 + your local taxes. Eventually, just under 2k Dollars looks about right. Could be a good reason to come to Washington this October...... 73 David Per reports from HamCation, MSRP is $2195.

ISS SSTV around 1710 UTC Saturday
by Patrick STODDARD (WD9EWK/VA7EWK) 09 Feb '19

09 Feb '19

Hi! During the last ISS pass over central Arizona at 1710 UTC, I copied a part of one picture starting about 15 seconds after AOS, followed by a clean and complete picture a couple of minutes later. This was during a 9.5-degree pass over central Arizona. Signal strength was more like I remember from past SSTV events, even when the ISS elevation was below 1 degree. A pass like this would have been impossible to hear yesterday. You can see these pictures at: https://twitter.com/WD9EWK/status/1094287865637269505 (1710 UTC pic) https://twitter.com/WD9EWK/status/1094288150329847808 (1712 UTC pic) Both were recorded by my TH-D74 with an Elk log periodic, and then decoded using RX-SSTV on a Windows 7 laptop. 73!

Geostationary & HEO Satellites
by Les Rayburn 09 Feb '19

09 Feb '19

I’m also a newcomer to the birds, but very excited about it. Likewise, I responded to the survey, but wanted to comment further regarding geostationary and HEO satellites. In the camp of “Both, please.” The HEO birds would once again offer the possibility of DXCC and make WAS more realistic—it also offers more operating challenges. But a geostationary amateur satellite would have many interesting benefits: Provide an easier introduction to satellite operation, and attract new operators. Excellent tool for emergency communications during a natural disaster. Opportunity to experiment with microwave operations. The ability to enjoy satellite operation any time of the day/night. The band is always open. I’m grateful for anyone who incorporates amateur radio into their satellites, but feel that birds should include either linear, digital, or FM transponders whenever possible. Designers are asking a lot of hams when they solicit our monitoring their telemetry signals, and using amateur spectrum for their purposes without much tangible benefit to us. My opinion only. It’s wonderful that they asked us. Dialogue is the key to most human accomplishment. 73, Les Rayburn, N1LF Maylene, AL EM63nf AMSAT #38965, ARRL Life Member, CVHS Life Member, SVHF Member

Fw: Operating SSB sats
by k6vug＠sbcglobal.net 08 Feb '19

08 Feb '19

Thanks Patrick. Not to spam the BB, but here is one last clip - working K7TAB via CAS-4B this morning. https://drive.google.com/open?id=1DYbg1Ua8_MfZnBjpngBjGxAApB5fcq82 I use the CW beacon to wait for adequate signal and then (at 00:40) switch to the transponder pair, adjusting the uplink with a tone burst until it comes in at about 800 Hz on the bottom display. After that I can move the down-link around the pass-band and don't have to worry about the uplink. HRD (and SatPC32) do a great job of handling the Doppler adjustments. Obviously, you'll notice the signal from the CAS-4B ges pretty strong as soon as it comes up above 15 degrees or so. I keep an eye on the CW beacon (at the left of the waterfall) throughout the pass and watch-out for fading due to foliage, buildings etc. Fast forward to 3:20, I've tuned to K7TAB and start responding. You'll notice that K7TAB drifts a little as he is speaking. However, you'll also notice that K7TAB has moved quite a lot AFTER I have responded and so I have to re-tune the down-link to hear the response properly. Well, that is the issue I wish to illustrate, and am still working on it.... :) Again, sorry for several posts, won't post any more until I have figured it out.

ISS SSTV - Old and New
by Robert Bruninga 08 Feb '19

08 Feb '19

Went out with a bunch of students to observe ISS SSTV downlink. ISS was transmitting but I demonstrated how not to do a pass: OLD FUD Approach: 1) Prepped the laptop. Battery was dead 2) rigged up heavy battery and 60 Hz inverter (1 hr to go) 3) Booted laptop but it was locked out of network 4) After three tires at password, it locked me out of all my accounts on every PC at the school 5) Gave up and dug out a Kenwood VC-H1 SSTV handheld to go with a TH-D72 (30m to AOS) 6) VC-H1 batteries were of course dead 7) Found new batteries (10m to AOS) 8) From 20 years ago, had a hard time remembering how to work it 9) Nothing heard at beginning with 3 element yagi 10) commented how this is not unusual for ISS to change schedules 11) Then heard it, but too weak 12) I explained how to track in AZ and EL and Polarity to maximize the signal 13) Had to keep asking the mids for the TIME so I knew where to point MELINNIAL APPROACH: MEANWHILE I noticed some of the students holding their Phones in their hands at arms length and waving them around. They pointed to ISS... The phones showed exactl;y where the ISS was as the AP placed the ISS and sky track on the sky view. Done! Im sure most of you are well aware of these things, but for the other old fuds: The AP was SKYGUIDE: https://itunes.apple.com/us/app/sky-guide/id576588894 And SKYWALK: https://itunes.apple.com/us/app/star-walk-explore-the-sky/id295430577 I am sure there are others.

A question came up in a local ham breakfast group. AO-7 and some upcoming launches have modes which include HF frequencies.

AMSAT-Francophone launches a consultation, open to all, on the amateur satellite radio service. Feel free to participate! Publié le 3 février 2019 par Xtophe
by christophe.mcr 08 Feb '19

08 Feb '19

Dear Satellite / nanosatellite project managers often wish to use amateur radio frequencies for educational and outreach purposes. The amateur radio community thus offers them a tremendous potential for monitoring their fragile conception. They often ask what kind of amateur radio experience would be interesting to board a cubesat or what services they could provide with their communications systems. The answer can be simple: a transponder, but these designers would like to bring novelty and innovation. In order to provide more factual input, AMSAT-F <http://site.amsat-f.org/> has decided to launch an online survey to find out what you do and would like to do as a satellite activity, what you expect from satellite designers and what you can bring to them. *The synthesis of these results will be presented at the second* AMSAT-F meetings « Rencontre spatiale radioamateur » on 9 and 10 March 2019 in Nanterre (France) <http://site.amsat-f.org/2019/01/29/deuxieme-rencontre-spatiale-radioamateur…> Do not hesitate, give your opinion by completing the questionnaire via the link : https://framaforms.org/amsat-francophone-survey-1548716436 <https://framaforms.org/amsat-francophone-survey-1548716436> The survey is in english but hosted on French server.

Hmmm, where to begin when so much opportunity is afoot? > ...

VHF/UHF Beacons in EM63pf
by Les Rayburn 08 Feb '19

08 Feb '19

With the considerable assistance of Marcus Thomas, KF4YHP, we’ve finally got the N1LF/B beacons on the air from EM63pf. The beacons are CW only, and located at the Pinnacle Lookout Tower, in Shelby County, Alabama, near Birmingham. 10 Meter: 28.268.5 MHz (3 Watts) 6 Meter: 50.068 (.5 Watt) 2 Meter: 144.300 (.5 Watt) 222: 222.068 (3 Watts) 432: 432.298 (10 Watts) If you’re nearby, or operating as a rover this may help with evaluating antennas, pre-amps, etc. Hope they encourage more weak signal DXing in the South. Receptions reports are welcome. 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL 35114 EM63nf AMSAT #38965, ARRL Life Member, CVHS Life Member, SVHF Member

I’d be interested in any sort of satellite CW. I am only able to work V/u like FO-29 since I’m currently just half-duplex on linears and need to adjust for downlink Doppler by ear. K5IX Dave SKCC #3026

Vhf/Uhf amplifier for Icom Z1A?
by Bob Hammond 07 Feb '19

Any recommendation for amplifiers for my Icom Z1A? I want to use it with my antennas while I no-so-patiently wait for the IC-9700. Bob W7OTJ DN17

There was interest in doing some straight key ops on the birds but lost the post. Anyone interested?
