WSJT & FCDPP
by Vincenzo Mone 24 Jun '18

24 Jun '18

Hi folks, please anybody can point me how to set the WSJT program to work with SDRSharp and the Funcube Dongle Pro Plus to decode the DSLWP satellite? I do not understand how to set the Audio ports. I have tried to set as Virtual Audio Cable but when i close and re open the program, i get the error: Error opening output audio stream. Errortext: Invalid number of channels Number: -9998 Error 2 in JTaudio, you will only be able to work offline. Please how to set? Any help will be really appreciated Thanks 73's de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.

FS: Kenwood TS2000 HF/VHF/UHF satellite radio
by John Geiger 23 Jun '18

23 Jun '18

I have for sale a Kenwood TS2000 radio that does 100 watts on HF, 6 meter, and 2 meters, and 50 watts on 70cm. It also does full duplex for the satellites. It has IF-DSP for noise reduction, auto notch, and narrow filtering, a built in TCXO for frequency stability, a built in CW memory keyer, and built in SWR meter. It is in good physical condition with a couple of scratches here and there. It is putting out rated power and works fine, except that every once in a great while the receive level will briefly drop. It will come right back and doesn't do it very often at all. It comes with the 4 button hand mic, a power cord, and the original box. I don't have a manual for it, but you can find those on line. I am asking $710 shipped for it which will also include paypal fees if you want to pay that way. This rig will let you do about everything in ham radio and is a good performer. I also have a Signalink USB digital modes interface and a rigblaster NOMIC interface for the TS2000 if you need one of those. 73 John AF5CC

Re: [amsat-bb] DSLWP-2 elements for GMAT?

Thanks, The most recent elements I could find was a tweet posted by Scott Tilley on June 9th. https://twitter.com/coastal8049/status/1005575611627139072 I think there have been some changes as they refine the orbit, but I’ll use those unless something newer surfaces.

Their main purpose for the trip is to activate EL84, one of the maidenhead grids with the least land area of any in the CONUS, on satellites and 6m. The team wrote, "We are scheduled to arrive around 11am (1500z) on July 6th, and stay through 3pm (1900z) on the 8th. "Two complete satellite stations are planned, with capabilities on all current amateur satellites. Emphasis will be especially on the larger footprints of AO-7 and FO-29, but we will work as many passes as possible during our time on the island. With two experienced satellite operators who have activating nearly 80 combined grids on satellites in 15 different states, we think we've got a pretty good chance of success in getting EL84 in the logs of anyone who needs it! This includes Europe and South America - if you are in the outer reaches of the footprint between EL84np and your location, let them know ahead of the trip so they can plan some possible low elevation pass skeds! "The 6m station will consist of a 2 element 6m beam at ~20 feet, an FT-857 100w transmitter, and capabilities on SSB, CW, and digi modes, emphasizing the JT suite - FT8, JT65, and possibly some MSK144 if conditions allow. We will be there in peak E skip season, so keep your fingers crossed for some great band openings! "We will also operate on HF as time, band conditions, and battery power allow. This is secondary to the 6m and satellite ops, with no hard planned schedule, so keep your eye on the dx cluster for K4R if you need EL84 for the ARRL international grid chase. As on 6m, we will have capabilities on CW, SSB, and digi. "We will be communicating largely via twitter.com/K4R_EL84 while on the island, using a Garmin InReach messenger to post informa- tion about frequencies, modes, and pass schedules. This is an open, public twitter page, so you can view it even if you don't have a twitter account. If you do have an account, be sure and follow us before the trip so you can stay up to date! We are also working out details on a pilot station who can relay sked requests and information to us via the satellite messenger - stay tuned here for more details on that as the trip approaches. "All logs will be uploaded to LOTW as soon as possible after the trip. Cards will also be available upon request." Visit the team's web page http://k4r2018.com/ for their latest information.

Same place on Parsons. I went over a couple of hours this morning and the place was packed for the picnic lunch. Looks like the same folks are still hard at work. Your shack is looking good. Congratulations. I am still working on the house and am close to getting up some weak signal antennas on 6,2, 220 and 432. I finally got the old antennas down. The new ones are HO loops. I will also put up a new discone. I have it ordered alreadly. I am thinking about a LPDA and a 1296 loop yagi on a small rotor also. These will work on the Florida Weak Signal group nets on 432 and 1296. I talked to AA4MD this week and he is still waiting on his 1296 transverter. The 600 watt amplifier has been delivered.

APRS contacts between passes at field day
by Robert Bruninga 23 Jun '18

23 Jun '18

While you are between Sat passes, you can use your APRS HT to make APRS contacts all over the country too. They wont count for FD contest points, unless it is direct with no digipeater, but the opportunity to make a bunch of live APRS contacts during a global contest should be fun! Simply activate your APRS station there by sending a Global CQ FD message to the world. Just send an APRS message to CQSRVR with the first words being CQ FD XX SSS... (where XX SSS is your category and ARRL section) This message will go to every other CQ FD site on the planet (if they have sent the same CQ message). To make a contact, when you see one of these CQ FD messages from the CQSRVR, then you simply send back an APRS message to their callsign direct. When he acknowledges it, then it is a contact. Of course, I have not even read the FD rules since, for a decade, such. APRS contacts do not count because they go via digipeaters. But HAVE FUN! Enjoy APRS and put your FD site on the map. Use the PORTABLE symbol which is a tent... For info on the global CQSRVR see: http://aprs.org/cqsrvr.html And you can use it for ANY global message group any day of the year too. For example CQ AMSAT or CQ JOTA or CQ IOTA, or CQ SOTA To keep the global traffic load down, you can only send one of these CQ messages once every 30 minutes, But when you see other callsigns, you can send direct message as many as you want since they go point-to-point.

Reminder! AMSAT Field Day Starts at 1800 UTC 23-Jun
by Paul Stoetzer 23 Jun '18

23 Jun '18

All those with satellite stations for Field Day, remember to calculate and submit your scores for AMSAT Field Day as well as ARRL Field Day. AMSAT Field Day allows working stations on multiple satellites, whereas ARRL rules count "satellite" as a single band (working a station on a second satellite is a dupe under ARRL rules). AMSAT Field Day also awards points for uploads and downloads of Field Day greetings from store-and-forward packet satellites (FalconSAT-3). See the AMSAT Field Day rules and submission requirements at https://www.amsat.org/field-day/. There are 4 FM satellites, 12 linear transponder satellites, and 3 digital satellites that will be operational during Field Day this year. Anyone looking for the 100 point ARRL Field Day bonus should be able to easily pick it up. FM AO-91 AO-92 (In L/v mode through 0158Z 24-Jun, U/v mode after) AO-85 SO-50 Linear Transponder AO-7 AO-73 CAS-4A CAS-4B EO-88 (Eclipse Only) FO-29 UKube-1 XW-2A XW-2B XW-2C XW-2D XW-2F Digital FalconSAT-3 (PBBS & Digipeater) NO-84 (PSK31 & Digipeater) LO-90 (FM Uplink / Codec2 Downlink) Satellite details are available at https://www.amsat.org/two-way-satellites/ . 73, Paul, N8HM

global satellite tracking !?

Does anyone know anything about this: https://www.stellarstation.com/amateur <https://www.stellarstation.com/amateur> ? UHF only for now, but some neat stuff here: https://stellarstation.helpscoutdocs.com/article/40-decoding-downloaded-iq <https://stellarstation.helpscoutdocs.com/article/40-decoding-downloaded-iq> Future updates here: https://stellarstation.helpscoutdocs.com/article/36-product-roadmap <https://stellarstation.helpscoutdocs.com/article/36-product-roadmap> Some fine print (enlarged for easier reading ;-): Regarding amateur frequencies: Amateur ground stations use special credits that are designated to only amateur frequencies. Credits that are earned by sharing commercial ground stations cannot be spent for using amateur ground stations. Additionally, credits earned through amateur ground stations cannot be converted to cash. The only way to access amateur ground stations in the StellarStation network is to share your existing amateur ground station to earn special credits designated for amateur frequencies. How it works: When you share your unused antenna time and earn credit, you can then spend your credit to access other antennas, dramatically expanding your communication window without paying for additional passes. Users without a ground station can simply sign up to use any compatible ground station on our platform with pay-as-you-go billing and no upfront costs. Work in progress? Vaporware? Too good to be true? Anyone willing to give it a try? Yes, I have signed up with SatNOGS, but my ground station is not yet complete… Butch K8KO

RF power required for linear satellites?
by Ken M 20 Jun '18

20 Jun '18

Hello AMSATers, I’m wondering if 5 watts is generally sufficient RF output to work the common linear satellites using a handheld satellite antenna (Arrow or Elk)? For example, would an FT-817ND (or the new FT-818) suffice for the uplink radio, or would you need an amplifier with those 5 (6) watt radios, or just a more powerful radio such as the FT-857D? Thanks & 73, Ken VA7KBM

by k6vug＠sbcglobal.net 19 Jun '18

Initially I planned to use N1MM+, and got it to work alongside SatPC32. N1MM & SatPC32 : https://drive.google.com/open?id=1lDiocYrz92OnfL1F0rttKhBOhfz68ShP However after reading old posts in the AMSAT-BB archives, I decided to log everything in a spreadsheet. And thanks to Erich, DK1TB, for enabling DDE in SatPC32, it makes things easier, the spreadsheet integrates with SatPC32 to grab the Satellite Name, Up/Dn Frequencies, Modes and Time. Then I can export the spreadsheet log as an ADI file. ( Since my other laptop does not have MS Excel, I ported it to Open Office Calc too. ) Spreadsheet using SatPC32 DDE : SatPC32_Logger.png I'll be using the club call KU6S for FD. 73!

In past years we have kept paper records during the event then typed them out for submission, but last year we vowed to find a logging program that would support satellite contacts. Even if we have to manually sort the ARRL from the AMSAT results at the end I think it would be worthwhile. So I'm looking for suggestions. Our club is using "N3FJP Field Day Contest Log" which I don't think allows logging the same contact on multiple satellites per AMSAT rules. Would "N3FJP Amateur Contact Log" be better suited? I don't mind paying for good software, especially if I can use it for my own satellite logging later. Or if an Excel spreadsheet is truly the best option then I'll consider that. Thanks and 73, Alex VA3ASE ------------------------------

Field Day Logging
by Stephan Greene 19 Jun '18

19 Jun '18

Our club uses N1MM+ with the HF stations networked. I run a stand alone copy that is never connected to the network or to my satellite radio. I assign one band to each satellite/band and manually switch "bands" at the start of a pass. This let's me manage dupes on each satellite and see where I have been working someone. After field day, I export the log to a spreadsheet and remove the dupes per ARRL rules, this info goes to the person sending in our log. Works for me and I don't mess up the FD network. I haven't checked if the N1MM dx-satellite mode accepts the FD exchange instead of a grid. It doesn't distinguish between satellites, so no dupe checking in real time. Steve KS1G

It will remain in full time transponder mode until at least Sunday PM (UTC). You may also wish to try UKube-1 and EO-88. As always, have FUN. 73s Jim G3WGM and the FUNCube team From: Jim Heck Sent: Sunday, June 17, 2018 8:14 PM To: amsat-bb(a)amsat.org Subject: AO-73/FUNcube Mode change Hi folks, I have just changed the sat into education mode (full power beacon in sunlight, low power beacon plus transponder on in darkness). Due to operator availability, it may not be possible to switch to full time transponder mode next weekend. 73s Jim G3WGM and the FUNcube team.

Field Day Logging
by VA3ASE 19 Jun '18

19 Jun '18

Hello friends, I'll be operating our club satellite station for Field Day and intend to submit results towards the club ARRL score as well as the AMSAT contest. In past years we have kept paper records during the event then typed them out for submission, but last year we vowed to find a logging program that would support satellite contacts. Even if we have to manually sort the ARRL from the AMSAT results at the end I think it would be worthwhile. So I'm looking for suggestions. Our club is using "N3FJP Field Day Contest Log" which I don't think allows logging the same contact on multiple satellites per AMSAT rules. Would "N3FJP Amateur Contact Log" be better suited? I don't mind paying for good software, especially if I can use it for my own satellite logging later. Or if an Excel spreadsheet is truly the best option then I'll consider that. Thanks and 73, Alex VA3ASE

Upcoming ARISS Events
by ka3hdo＠gmail.com 19 Jun '18

19 Jun '18

All, Several upcoming ARISS events: ARISS-Russia, in collaboration with the Southwest State University in Kursk, Russia, are developing a series of educational CubeSat satellites called Tanusha. Two Tanusha CubeSats were developed by students at Southwest State University and were hand-deployed by cosmonauts during an August 2017 extravehicular activity. These two CubeSats are performing cluster flight experiments through communications links. A second set of CubeSats, Tanusha 3 & 4 were launched earlier this year and are currently on-board ISS. Tanusha 3 & 4 are planned to be hand deployed by Cosmonauts in August. They will perform even more comprehensive cluster flight objectives than Tanusha 1 & 2. On June 20, Tanusha 3 will be connected to one of the ARISS Service Module antennas and will transmit from 0730-1200 UTC on 437.05 MHz. These FM transmissions will include greetings from students in several languages, including Russian, English, Spanish and Chinese. On June 21, Tanusha 4 will be connected to one of the ARISS Service Module antennas and will transmit from 0730-1200 UTC on the same frequency: 437.05 MHz. The ARISS-Russia team plan to also retransmit these signals on the standard ARISS 2-meter downlink, 145.80 MHz using the JVC Kenwood D700 radio that is still on-board ISS. All are invited to listen to the CubeSats from ISS on 437.05 and/or 145.80 MHz. The next SSTV image downlinks are planned for June 29-July 1. These images will commemorate the various satellites that the ARISS team has developed and hand-deployed from the ISS. These will include the first satellite deployment from ISS: SuitSat-1/Radioskaf-1 which was deployed in February 2006. More details on this will be forthcoming as the date draws near. We thank ARISS-Russia delegate Sergey Samburov, RV3DR for this latest information. 73, Frank Bauer, KA3HDO -------------------------------------------- Frank H.

In the United States, sponsors are the American Radio Relay League (ARRL), the Radio Amateur Satellite Corporation (AMSAT), Center for the Advancement of Science in Space (CASIS) 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 informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

Satellites Contacts for Field Day 101
by Bandman444＠yahoo.com 19 Jun '18

19 Jun '18

This will be the first time our club station has our satellite rig up and running and I wanted to learn from the experts about tips field Day satellite contacts. My understanding there is some bonus for a satellite contact, and likely many will be on the birds. What do you recommend to someone who is fairly familiar with making satellite contacts, but never during field day? Thanks! Bryce Chanes KR0CKT

WinAOS is great to list passes for a given date and Countd is good for field events with a laptop. Both are part of both part of SatPC32. For hand held activity, I copy predictions form amsat.org into a spreadsheet. Then a macro filters the passes by max elevation and time of day and exports the result as an iCal file. Finally, the iCal file is imported into my Google Calendar. Its a little bit of work once a few month, but it conveniently pings me X minutes before the next pass and don't have to carry printed copies. There have been other apps and suggestions but found these to be most convenient, after trying several other ones. 73!

Re: [amsat-bb] Unsuccessful Uplinks - AO-92
by Hugo Dominguez, Jr. 17 Jun '18

Just tried trusty AO-91 and heard nothing through the duplexer. After it reached max peak I disconnected my D74, which was doing the receiving, from the duplexer and connected it directly to my Elk antenna. Right away I heard people talking. I then tried keeping the antenna on the bird where I heard audio and switching back to the duplexer and heard nothing. Not sure what is wrong. I need to find someone to test with on the ground. I’ll do more tests with another radio. Just need to get my third radio from another location. I tested on a 440 repeater and sending/receiving to duplex to myself.

I tested it on AO-92 on the last past around 1730Z but had a hard time hearing anyone until right before the LOS, I then heard something for a second as I was moving around my elk. I thought I would have heard the bird since I was on a hill with no obstructions to the bird. The only difference being I had the duplexer connected. I'll test it out more today. I made sure the duplexer works by transmitting on the frequencies allowed on each port of the MFJ (VHF/UHF) and was able to hear myself on another radio. It is such a hassle now carrying two radios and two cables coming out of the duplexor and putting one radio in my pocket. LOL. Luckily the D74 supports bluetooth so I will use that to eliminate an additional cable that gets tangled, so that I can hear. I just attached the MFJ duplexer to the handle of my Elk antenna to free up my hand temporarily to see how that works. I hope it won't interfere with the SWR.

I personally would like to stay and be wrapped at 9 PM not 530. For me some of the best Satellite passes will be in the early evening.

The CONOPS that Bob WB4APR has outlined is sufficient to qualify as a QSO. Both parties have sent their call and exchange, received same from the other party, and have mutually acknowledged receipt.

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) 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 informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

EN75 Cheboygan WM2100 2300z-2400z The After Party: Tuesday (A non-WMPLOTA event) -EN75 holiday style Individual passes will be determined as we get closer, more time will be spent in Tawas and Alpena, as there is only 1 WM in the grid. Follow me on twitter @andrewbnortham or http://twitter.com/andrewbnortham for up to the minute pass information, feel free to unfollow me on 7/3, DM to get on my hit list. I will try and work a minimum of 1 FM and 1 Linear bird from each location. AO 85/91/92, SO-50, FO-29, XW's, AO-7 and FalconSat-3 all planned. All the Walmarts in that regions, along with my campsite on 7/2 fall into a VUCC circle I am hoping to make a big dent in. If there is room on the birds, please work me. --Andrew/KE8FZT andrewbnortham(a)gmail.com http://twitter.com/andrewbnortham

Just to clarify one thing you think this is a late model Kenpro due to it having the switches and cap inside the casing attached above the positioning pot? >> >> I tested the motor last night using the KR400 controller, wiring seems standard on pins 4,5 and 6 so I gave it a couple of briefs bursts to see if it turned, it didn't! Well not initially then all appeared OK, on closer inspection I discovered that the motor itself has some form of brake or stop inside. While it's free to be turned manually in the same direction it was last powered it will not turn in the opposite direction until power is applied to move it that way. At first I thought it was jammed or broken but it appears to be normal operation as the rotation is quite free with no nasty feeling rough spots. >> >> The limit switches surprised me as well. I come from a satellite background where I'm used to a limit switch killing power to an actuator, if I press one of these it switches the motor into the opposite direction, is that right? >> >> Now I know the motor is free to move I've purchased new bearings and will source some suitable grease, primer and paint. The case has become quite pitted inside where the water was laying but it's now all clean after wire brushing and rubbing down.

Generate times for FD satellite passes
by Tom Schaefer 17 Jun '18

17 Jun '18

Can anyone recommend an easy way to generate a list of all satellite passes for a particular grid for a whole weekend? I would like to pick a list of sats, a grid and a date range and get a list of passes for that time I can print out. I can do it for a single sat and paste it into a spreadsheet then sort by time but I hope that problem has already been solved. Thanks Tom NY4I Principal Solutions Architect Better Software Solutions, Inc. 727-437-2771

Reset SatPC32 window position
by Thomas Schaefer 17 Jun '18

17 Jun '18

Does anyone know where the saved window position is kept for SatPC32? I ask as last time I used SatPC32, I had 2 monitors. SatPC32 was on the other monitor. It does not appear to detect that the system now has a single monitor and bring the window into the viewable area. When I run the program, it is starting on the second monitor and I need to reset its saved position. Thanks, Tom NY4I

Working APRS
by Hugo Dominguez, Jr. 17 Jun '18

17 Jun '18

This weekend I decided to try APRS on the ISS, NO-44 and AO-84. So far I have heard nothing on the ISS. I've heard that the radio is down. Is it still down completely or only for certain frequencies? Are any available on the ISS? I was using 145.825 for the ISS and AO-84 on APRS. I did hear a sound shortly yesterday either on AO-84 or NO-44, but not long enough to receive packets. I've also tried the ISS on 437.550. This page shows that APRS was last heard 1 week and 1 day ago https://www.issfanclub.com I'll try AO-84 in a minute to see again. What other birds does anyone recommend for APRS? NExt I will try PSK31. LEarning one new thing at a time with the birds -- Hugo Dominguez, Jr.

Re: [amsat-bb] Working APRS

Hugo, ISS is down indefinitely for APRS. There is a new system on earth that is waiting for a ride to the station, but until then - don't count on ISS packet. Their voice system seems to still work fine, so you may get lucky if you call them (but probably not - I've tried 100 times over the last 2 yeara, and nobody ever returns my call). NO-84 works just fine when the digipeater is on. If the battery voltage falls too low, then the digipeater turns off and has to be manually reset (And I think DK3WN is the only command station currently). NO-44 is very difficult to work. User agreement explicitly states that you are not to attempt digipeating using the "W3ADO" path, but that seems to be the only one that works. I've tried a few times when it was in "PCSAT" mode and it just flips to W3ADO, or sends a poor excuse for a packet that won't decode. The only other packet option is Falconsat-3, which is 9600bps. It is always on, however, but takes more skill to operate than the 1200bps sats. --Roy K3RLD > This weekend I decided to try APRS on the ISS, NO-44 and AO-84.

HRD Satellite Tracking Question
by Dave Tipton, W5DMT 17 Jun '18

17 Jun '18

I was trying to setup HRD last night, and the strangest thing. When I go into options, to put in my grid square, it is grayed out. It shows me in the Atlantic Ocean, off the coast of West Africa. To make it even stranger, it says (grayed out again) that I'm in EM65. Loaded it on the laptop we're planning to use for field day next weekend, and it was the same. What am I missing here? I did set up myself in the observers section, but that didn't seem to change anything either. Thanks, Dave Dave Tipton, W5DMT (615) 689-0685 <mailto:[email protected]> dave(a)w5dmt.com

Re: [amsat-bb] APRS FD method
by k6vug＠sbcglobal.net 16 Jun '18

16 Jun '18

Hi, I can't believe I'm jumping on a discussion by THE experts - Bob, Patrick and others. I must confess that I have sometimes used MHEARD to ACK several callsigns all at once, with very limited success. Since this was an impromptu approach, the other stations had no idea that I was trying to save air time. ( sorry the idea using a beacon as a CQ/ACK never occurred but is quite interesting ) Secondly, I have used UISS with ACK enabled only because I had a non-optimal TX antenna and wanted a "physical layer ACK", to ensure my packets were being heard at the bird. The good thing is that once I got this, I was essentially off the air waiting for a response to my CQ or QSO ACK. I did however set the path to satellite callsign only. Thirdly, I'll be using a portable setup with laptop et al - SatPC32, SDRsharp (as RX), IC7000 (as TX), and a logging program. Lastly, this is my AHHA moment - now I know how I get QSO ACKs from Patrick so fast, while I have to struggle with UISS screen to send my QSO ACK. Most enlightening discussion ! 73! Umesh, K6VUG ------------------------------ Message: 9 Date: Sun, 17 Jun 2018 00:05:46 +0000 (UTC) From: Ryan Noguchi <ai6do(a)yahoo.com> To: AMSAT <amsat-bb(a)amsat.org> Subject: Re: [amsat-bb] APRS FD method Message-ID: <2021625973.717858.1529193946171(a)mail.yahoo.com> Content-Type: text/plain; charset=UTF-8 >I am not sure your approach would meet the definition of a >complete QSO.

Yes, that's correct. The CONOPS that Bob WB4APR has outlined is sufficient to qualify as a QSO. Both parties have sent their call and exchange, received same from the other party, and have mutually acknowledged receipt. Both A and B are calling CQ in each beacon they transmit. They simply append the calls of the stations they are "answering" at the same time that they call CQ themselves.? The elegance of the concept is that all communications are beacons--with everyone calling CQ and answering other CQers at the same time--rather than point-to-point messages. It's a very efficient use of the limited resource.?I like the idea in principle. >Add in the time of having to edit the status text on the?>APRS-ready radios, and it gets messy fast. This is my second biggest concern with the concept, especially for those of us who will not be at a computer terminal. I tend to agree that this may be cumbersome to implement on just an HT, but I'll try it out to see how it compares.? What I think is a more fatal flaw is that this just isn't the way we do things the other 363 days of the year. It isn't just a matter of "saying something different" on Field Day. This is a fundamentally different way to make QSOs than we do on packet satellites every other day but Field Day, which is not a recipe for success. It's a classic game theory problem. If I'm the only one following this protocol, I won't be making any QSOs.? Has anyone in recent history successfully made an APRS Field Day QSO in the manner that Bob describes? 73, Ryan AI6DO ------------------------------

ANS-168 AMSAT News Service Weekly Bulletins
by Lee McLamb 16 Jun '18

16 Jun '18

AMSAT NEWS SERVICE ANS-168 The AMSAT News Service bulletins are a free, weekly news and infor- mation service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor at amsat.org. In this edition: * AMSAT Field Day on the Satellites * CAMSAT Details on Three Satellites and an HF Transponder * 3A Monaco Activation on FM Satellites in July * ARISS Ham Video Transmitter Aboard ISS Defective * Call for Volunteers, ANS Seeks Rotating Editors SB SAT @ AMSAT $ANS-168.01 ANS-168 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 168.01 From AMSAT HQ KENSINGTON, MD. DATE June 17, 2018 To All RADIO AMATEURS BID: $ANS-168.01 AMSAT Field Day on the Satellites It’s that time of year again; summer and Field Day! Each year the American Radio Relay League (ARRL) sponsors Field Day as a “picnic, a campout, practice for emergencies, an informal contest and, most of all, FUN!” The event takes place during a 23-hour period on the fourth weekend of June. For 2018 the event takes place during a 27-hour period from 1800 UTC on Saturday, June 23, 2018 through 2100 UTC on Sunday, June 24, 2018. Those who set up prior to 1800 UTC on June 23 can operate only 24 hours. The Radio Amateur Satellite Corporation (AMSAT) promotes its own version of Field Day for operation via the amateur sat- ellites, held concurrently with the ARRL event. This year should be easier than many years since we have more than 10 transponders and repeaters available. Users should check the AMSAT status page at http://www.amsat.org/status/ and the pages at http://www.amsat.org/?page_id=177 for what is available in the weeks leading up to field day. To reduce the amount of time to research each satellite, see the current FM satellite table at http://www.amsat.org/?page_id=5012 and the current linear satellite table at http://www.amsat.org/?page_id=5033 If you are considering ONLY the FM voice satellites, there are SO-50, AO-85, AO-91, and AO-92. It might be easier this year to make that one FM contact for the ARRL bonus points with so many FM birds. The congestion on FM LEO satellites is always so intense that we must continue to limit their use to one-QSO-per-FM-satellite. This includes the International Space Station. You will be allowed one QSO if the ISS is operating Voice. AO-92 may be in L/v for the first part of the event, depending on command station availability. Keep an eye on @AMSAT on Twitter for expected L/v mode change times. The full set of rules are posted at: https://www.amsat.org/field-day/ [ANS thanks AMSAT Director Contests and Awards, Bruce Paige, KK5DO, for the above information] --------------------------------------------------------------------- CAMSAT Details on Three Satellites and an HF Transponder CAMSAT, China’s Amateur Radio Satellite organization, has offered additional details about the three Amateur Radio satellites it plans to launch later this year. Two of the satellites, designated CAS-5A and CAS-6, will carry transponders, and one of them will offer HF capability. CAMSAT’s Alan Kung, BA1DU, told ARRL that the 6U CAS-5A will carry two HF transponders and two V/UHF trans- ponders. The plentiful equipment package includes an H/T (21/29 MHz) mode linear transponder, an H/U (21/435 MHz) mode linear transponder, an HF CW telemetry beacon, a V/U linear transponder, a V/U FM trans- ponder, a UHF CW telemetry beacon, and UHF AX.25 4.8k/9.6k baud GMSK telemetry. + The H/T mode linear transponder will have a 30 kHz wide uplink centered on 21.400 MHz, and a downlink centered on 29.490 MHz. RF output is 0.5 W. + An HF CW telemetry beacon will transmit on 29.465 MHz with 0.1 W. + The H/U mode linear transponder will have a 15 kHz wide uplink centered on 21.435 MHz, and a downlink centered on 435.505 MHz. The RF output is 0.5 W. + The V/U mode linear transponder will have a 30 kHz wide uplink at 145.820 MHz, and a downlink at 435.540 MHz. The RF output is 0.5 W. + The V/U mode FM transponder will uplink at 145.925 MHz, and downlink at 435.600 MHz. The transponder passband is 15 kHz, and the RF output is 0.5 W. + The UHF CW telemetry beacon will transmit on 435.570 MHz, with an RF output of 0.1 W. + UHF AX.25 4.8k/9.6k baud GMSK telemetry will transmit on 435.650 MHz at 0.5 W. Kung told ARRL that the HF, VHF, and UHF antennas are quarter-wave monopoles. A satellite within a satellite, the tiny CAS-5B, weighing 0.5 kilogram, will be deployed from CAS-5A in orbit. It will carry a UHF CW beacon on an Amateur Radio frequency. Both CAS-5A and CAS-5B will be placed into 539 × 533 kilometer, 97.5° orbits. They will launch from the Jiuquan Satellite Launch Center in late September. The 50-kilogram CAS-6 microsat will include a VHF CW telemetry beacon, a U/V mode 20 kHz linear Amateur Radio transponder, and AX.25 4.8k baud GMSK telemetry. It will also carry an atmospheric wind detector and other systems that will operate on non-amateur frequencies. A launch at sea on an as-yet undetermined date is planned for CAS-6 from the China Academy of Launch Vehicle Technology. The microsat will be placed into a 579 × 579 kilometer, 45° orbit. [ANS thanks ARRL for the above information] --------------------------------------------------------------------- 3A Monaco Activation on FM Satellites in July F4DXV plans FM satellite operation from 3A Monaco (JN33) on Monday 02 July ~08:30z to 13z only during a quick break from his trip to Italy. Jerome says, "Due to a bad horizon (mountains, buildings), I could be only QRV for EU on high FM orbits." [ANS thanks Daily DX for the above information] --------------------------------------------------------------------- ARISS Ham Video Transmitter Aboard ISS Defective Gaston Bertels, ON4WF has provided an update regarding the condition of the ARISS HamTV system aboard the ISS. In mid-April, the Ham Video transmitter on board the Columbus module of the ISS stopped working. Extensive testing was performed by the crew on June 1, 2018 which comprised connecting the transmitter to the second ARISS L/S-band patch antenna on the nadir of Columbus. The test was negative. Ground stations did not receive any signal from Ham Video. Since on-board repair is impossible ARISS is planning to return the transmitter to Earth. Bertels wrote, "We hope this plan will be accepted by the space agencies and the cost of operations funded by sponsors. Schools and crew members performing educational ARISS school contacts are delighted to use Ham Video. We will do the best we can to restart this service as soon as possible. We will keep you informed on progress." Additional information about the HamTV project can be found on-line at: https://www.amsat-on.be/ [ANS thanks Gaston Bertels, ON4WF and ARISS HamTV for the above information] --------------------------------------------------------------------- Call for Volunteers, ANS Seeks Rotating Editors The AMSAT News Service (ANS) is seeking volunteers to serve as rotating editors for its weekly newsletter. Editors work on a rotating schedule, each taking a different turn editing a specific week's newsletter as scheduled by the ANS Editor in Chief. Editors support each other by seeking and reporting to the Editor of the week, information and resources of interest to the AMSAT community.

Another KR500 thread, maybe.
by Paul 16 Jun '18

16 Jun '18

Hi all I recently won a Kenpro KR500 rotor on Ebay for the princely sum of a quid. The alleged history was it was purchased, had antennas attached but was never wired or used and this I can believe because the connector block looks untouched. It was however left on its side in the garden so looks pristine but has suffered water ingress. I started to strip it down today and of course the eight M6 Phillips heads put up quite a fight but I attacked it with fire and it is now apart. Having opened it up I'm now slightly confused as to what model rotor I actually have. It has the eight screw terminal block, the casing is stamped Kenpro but internally it has the limit switches and a capacitor. The controller I intend using is an old Kenpro KR400 model and I assume has the 70uF cap across the switches. Do I leave this in place to use it with my rotor or should I remove it, or remove the cap in the rotor? Paul G7PUV Sussex Coast. JO00

APRS FD method
by Robert Bruninga 16 Jun '18

16 Jun '18

I welcome Rules Feedback, but this is the OPTIMUM way to make FD contacts via a satellite from an APRS radio with the least congestion. DO NOT USE MESSAGES. They will choke the channel with retries and no one will get through. Set your path via the correct Satellite DIGI callsign and turn off proportional pathing and auto-decay. Set interval to 30 seconds. Place your CATEGORY and SECTION in your STATUS text and set beacon time to once a minute. You don't need GRID since all APRS radios display that on receipt based on the position. SO here is your STATUS at the start: CQFD 3AMDC (category and section) Then every time you see someone else's info, QSL them by pressing the F key and SEL button 5 times and it will go directly to place the cursor at the end of your status text for you to add the first contact call: CQFD 3AMDC QSL WB4APR And then when you see the next one, add the next call: CQFD 3AMDC QSL WB4APR,W3ADO And so on. You can be acking up to 4 calls at a time. And your CQ and acks are all in a single packet. You can only count the calls as 2-way if you also see your call in the QSL list of the other station. When you get to 4 calls, then ERASE the first one, and add the next one at the end. and so on. This method keeps the channel load low, automatically captures and records other stations in your STATION LIST and automatically sends your QSL's in your next automatic beacon. This lets you spend your time reviewing the lists, deciding who you have received QSL's from and entering the next calls in your STATUS text. PRACTICE. Yes, pressing F key and SEL key 4 times will get you there since it will go to APRS, then STATUS TEXT, then SELECT the existing one, then SELECT it for editing, and then the cursor goes to the end so you can edit it. You should WRITE down any packets that have your callsign QSLed in them, since once that station has entered 4 more calls, yours drops off his beacon and so your STATION list will no longer have a copy of your call, just his latest 4. In my mind, this is a legal 2-way. You both exchanged grids, and category and section and QSLed and saw your call acknowledged. Again, NEVER us APRS "MESSGE" format via a satellite. It is tremendously inefficient and clogs the channel with retries because the ACKs just dont get through. That's why we invented APRS in the first place. TO get away from the abysimal success of ACKS on a crowded channel. Bob, WB4APR

Re: [amsat-bb] Falconsat-3 pass attempt.
by Ryan Noguchi 16 Jun '18

16 Jun '18

Include your CQ call in your StatusText field. Mine currently reads "CQ APRS AI6DO DM03" but I'll change that for Field Day to include both my exchange and my grid. Send your beacon (preferably manually) to "call CQ." Dont expect to get your own beacon back. Most of the time you won't. Properly formatted APRS messages are best as most portable ops won't be able to decode anything else. I also put "QSL de AI6DO" or something similar in my acknowledgment message text. If you responded to my CQ with your exchange and you get an ACK packet from me, the three way QSO is complete, since I'm not running an unattended station. Hope to hear you on! The farthest I've gotten with FS-3 is EM10, so I may be able to QSO with you if the timing is right. Good luck! 73, Ryan AI6DO On Saturday, June 16, 2018, 9:16:10 AM PDT, <tjschuessler(a)verizon.net> wrote: Hi all, Am trying to figure out this Falconsat-3 digipeating thing and have ben on several passes this Saturday morning with only N1RCN heard early.

Re: [amsat-bb] Funcube Dongle Pro+

Paul, here are some specifics for SDR# and FCDP/FCDP+, even RTL-SDRs are supported. Here is link to SDR# https://airspy.com/download/ I assume you're running Windows? Top file option. It's quite easy to get going, once you get a feel for it. After you have SDR# running with your FCDP+, then go get the SatPC32 plugin here: http://www.satsignal.eu/software/DDETracker.html Specifically, get this file first: http://www.satsignal.eu/software/DDETrackerV8Binaries.zip Use the website and the files in the .zip to get it configured. The key is to edit a config file and to add a specific line of text, that way the new DDE Sat plugin will show up in SDR# Once you have it configured, then update the DLL with this one, to be current: http://www.satsignal.eu/software/DDETracker.dll-20-Aug-2017.zip If successful ;) a new plugin will appear on the left column in SDR#. You click it, tell it you're using SatPC32 (needs to be running!), and click to start it...pretty intuitive. Then SDR# will track the downlink frequency and mode of the receiver freq. in SatPC32. Very slick :) Mark N8MH At 04:15 PM 6/12/2018 -0400, Mark L.

Re: [amsat-bb] Unsuccessful Uplinks AO-92
by John Marranca, Jr 12 Jun '18

12 Jun '18

I never would have considered a preamp with the Baofeng. But it's an interesting concept. Comparing my 2AT to the UV5RA is like comparing night to day. Even with a simple dipole mocked up with a BNC to Banana Post adaptor, most passes are solid with little fading or drop outs. Coupled with my HTX404 and a pair of Lindys should make for a really good station.

I agree about the Baofengs being somewhat deaf. In the past, I was able a few times to work SO-50 with the UV3R that I used to carry...and recently the UV5RA and dual-band whip has been used during the day while I'm out working. I thought that AO-91/92 sounded pretty good. That is, until I hooked up my 40 year old IC-2AT to my turnstile. AMAZING how well the ancient Icom can hear. Who knew?! KB2HSH

Unsuccessful Uplinks - AO-92
by Hugo Dominguez, Jr. 12 Jun '18

12 Jun '18

I’ve just started playing with talking on satellites. I’m able to hear all the satellites (AO-85, AO-91, AO-92 and SO-50) that I have programmed on my Kenwood TH-D74, which I use with my Elk dual band periodic log antenna. However no one can hear me or responds to me. I’ve only been successful with my uplink (being heard) on AO-91 on several passes. I triple checked my frequencies on my radio and the 67 Hz tone and they are set as follows: Sat. Xmit Tone SO-50 145.850 67.0 Hz AO-85 435.170 67.0 Hz AO-91 435.250 67.0 HZ AO-92 435.350 67.0 Hz These are the frequencies used when the bird is at its peak. I adjust for doppler on 440 by starting out 10 khz less, e.g AO-85 435.160, 435.165, 435.170, 435.175, 435.180. Any ideas if something has changed from what is published or am I missing something? Like I said, i’ve been able to communicate on AO-91. — Hugo Dominguez, Jr.

Long-time SatPC32 user but new to SatPC32ISS. Rig control works fine, but I can't get rotor control working in SatPC32ISS.

(I'm using Config II with SatPC32). Have not found anything (yet) in the SatPC32 docs. Thanks, 73 Steve KS1G

I took a little detour from chasing grids to try FT8 on 6 meters. What amazed me was the quickness of QSLs on LoTW, often finding the QSL awaiting when I uploaded my QSO. Why are the FT8-ers so fast compared with my experience on satellites. My guess is that FT8 QSOs are done with computer software with logging capability. But that can't be the entire reason. Most of our wonderful rovers are extremely fast getting their audio recording logs uploaded to LoTW. So motivation has to be part of the solution. Satellites can be worked without computer assistance, but Doppler control, pass prediction and logging make the activity more enjoyable for me. Some of the rovers should publish their procedure for logging to LoTW. Most logging programs will upload to LoTW. Even the TQSL program for LoTW handles hand-input parameters. And LoTW is the easiest way to apply for ARRL Awards. Perhaps my disappointment after working a needed grid and not getting an LoTW QSL can be relieved. 73, Ron W5RKN

Re: [amsat-bb] APRS balloon down in WV-back up now!
by Robert Bruninga 08 Jun '18

08 Jun '18

Well, my prediction was off, but guess what!?? It took off again when the sun came up and warmed the balloon. That is amazing. SO it took off from around Martinsburg WV and was over Baltimore at around 3 PM this afternoon above 39,000 feet and headed Southeast at about 60 MPH. Problem is that it has a terrestrial GPS that shuts down above a certain altitude to keep legal, and so it wont be transmitting again until it descends this evening. But at that speed, my guess it was over the ocean 2 hours later. Maybe it will survive till Europe? If it can take off rom water like it did from land this morning.

Icom W32A transmit below 440 for satellite work?
by Kevin M 08 Jun '18

08 Jun '18

"Or is it necessary to perform a hardware mod to get it to do so? If so, is there someone who has done the mod (successfully) who can provide documentation on what he did that worked?" There is a surface mount diode (D523) that needs to be removed to allow TX below 440 Mhz. Not the best documentation, but I followed this to modify mine: http://www.qsl.net/kf4tuz/icomhacks.html By the way, if you perform the RX modification on that page (just pushing some buttons, no soldering or even screwdrivers involved) and you are able to access the 800 Mhz band, then you have one of the units that should work full duplex on SO-50 well. If not, then you will likely find it's only semi duplex on SO-50, but fine on the U/v birds. 73 & GL, Kevin N4UFO

Icom W32A transmit below 440 for satellite work?
by David Jaffe 08 Jun '18

08 Jun '18

Hi, New to the list. I have an Icom W32A HT (one of the 5-digit serial number ones, ca. 1998) and an Arrow antenna. I used them around 10 years ago for AO-27 and, after reading the recent QST article, thought I'd try some of the newer satellites. Much to my surprise, I can't seem to get the W32A to transmit below 440 MHz., so I can't use it on AO-85, AO-91, etc. I looked at the specs and, sure enough, it says that it transmits only about 440 MHz. Yet, a google search seems to indicate that this was a popular satellite radio. Is there some trick to getting it to transmit below 440? Or is it necessary to perform a hardware mod to get it to do so? If so, is there someone who has done the mod (successfully) who can provide documentation on what he did that worked? Thanks K6DAJ

Re: [amsat-bb] Unsuccessful Uplinks - AO-92
by John Belstner 07 Jun '18

07 Jun '18

I have been been quite successful on SO-50, AO-85, AO-91 and AO-92 with 5W from my TH-D72A (full duplex) and Arrow antenna; even at low elevations. I think you will find that poor operating behavior from others on the bird is the primary reason for not being able to get through on any given pass. John - W9EN

Drew KO4MA, is absolutely right, operating full duplex is the best way to work these satellites. Having said that, I was stumped once when I heard the AO-92 downlink "full quieting" for the entire pass but could not get into the uplink. Strangely enough, I heard only 2 stations calling and no one responding. It was pretty frustrating, making me doubt everything I had learned so far. Then one day, I found out (right here on this BBS) that the satellite switches to L/V mode, then it all made sense. Now I always check the current status page at AMSAT.ORG especially when operating AO-92. I also learned about why it difficult to get into AO-85 with a HT. Keep reading, you'll learn a lot here from the gurus... trust me :) Good luck on the next pass... 73!Umeshk6vug ------------------------------ Message: 12 Date: Wed, 6 Jun 2018 20:25:49 -0400 From: "Andrew Glasbrenner" <glasbrenner(a)mindspring.com> To: "'Hugo Dominguez, Jr.'" <hugois(a)gmail.com>, <amsat-bb(a)amsat.org> Subject: Re: [amsat-bb] Unsuccessful Uplinks - AO-92 Message-ID: <002c01d3fdf6$16120c20$42362460$(a)mindspring.com> Content-Type: text/plain; charset="UTF-8" You've discovered one of the reasons full duplex is best on the FM sats...you have no idea if you are getting through, because you can't hear while transmitting.

I?m able to hear all the satellites (AO-85, AO-91, AO-92 and SO-50) that I have programmed on my Kenwood TH-D74, which I use with my Elk dual band periodic log antenna. However no one can hear me or responds to me. I?ve only been successful with my uplink (being heard) on AO-91 on several passes. I triple checked my frequencies on my radio and the 67 Hz tone and they are set as follows: Sat. Xmit Tone SO-50 145.850 67.0 Hz AO-85 435.170 67.0 Hz AO-91 435.250 67.0 HZ AO-92 435.350 67.0 Hz These are the frequencies used when the bird is at its peak. I adjust for doppler on 440 by starting out 10 khz less, e.g AO-85 435.160, 435.165, 435.170, 435.175, 435.180. Any ideas if something has changed from what is published or am I missing something? Like I said, i?ve been able to communicate on AO-91. ? Hugo Dominguez, Jr. ------------------------------

Hugo, you wrote, "perform doppler shift by starting 10 kHz below and work your way up", but this should not be generalized because the Doppler correction is opposite for the Receiver and the Transmitter. (1) At the Receiver - - when the transmitter (bird) is coming towards you, its frequency appears higher than its real frequency - when the transmitter (bird) is going away from you, its frequency appears lower than its real frequency (2) So, ideally, the Transmitter, has to compensate the opposite way, to be received at the correct frequency. (3) But since the satellite does not use Doppler corrections, the ground station has to provide the correction for both RX as well as TX. If you like, you can read the amazing article "The One True Rule For Doppler Correction", published by AMSAT in 1994. The key words are "AT THE SATELLITE". Also, just watch the frequencies shown by any satellite tracking program like SatPC32 or HRD Sat Tracker, and you'll see what is really going on. Happy bird hunting...! 73!

All the web pages I read said to perform doppler shift by starting 10 kHz below and work your way up. Even this amsat website has instructions to do it how I am doing it: https://amsat-uk.org/2018/01/26/ao-92-open-for-amateur-radio-use/ I also just noticed that there is a schedule for the L-band for uplink which i?m interpreting that UHF won?t work when the bird is setup for the L-band for uplink. Maybe I was trying to make contact when it was on the L band. ? Hugo Dominguez, Jr.
