[Video] HuskySat-1 decoded with manual tuning and no SDR
by John Brier 02 Feb '20

02 Feb '20

After some difficulty, I was able to decode HuskySat-1 on my second attempt. https://youtu.be/CisgT_umZQM One thing I didn't mention in the video, at the end of the pass around 10 degrees elevation and lower I decoded a lot of frames because the signal was still strong and by that point the frequency wasn't changing much anymore, as the satellite's relative speed stopped changing. Thank you again to University of Washington for launching this satellite and putting the AMSAT linear transponder on it! I wish you luck in all your missions! Check out the UW video about their satellite: https://youtu.be/U57sES6oFgw 73, John Brier KG4AKV

Re: [amsat-bb] Tuning HuskySat-1 telemetry signal
by Mark L. Hammond 02 Feb '20

Mine looks the same--using dot product (DP) decoder as well. The eye looks prettier on Costas, but here copy isn't quite as good as the DP. Using object "G" my recent 86 deg pass was fully automated! Carrier ranged from like 1460 up to 1600 back down to 1450 ish again....super nice. For IC-9700 users--AF over USB works fine, as does AF out of ACC 1 jack on rear, as does AF out of Main EXT-SP jack on rear. (Not having much luck using IQ for now...)

Building FoxTelem (follow up from Error accessing FunCube Pro...)
by Joseph Armbruster 02 Feb '20

02 Feb '20

Chris (et al), This is a reference for anyone attempting to build FoxTelem independently and maybe hack at it a bit. The current source available in github is technically incomplete and can not be used to reproduce a release version. I used master @ 7dd26797c88c30c9e6311907074eea037b394048. Chris, if you can provide the missing pieces for me, I can create a clean-patch that fixes that various pieces and allows it to build cleanly out of github. I'll submit a patch back to you, if you'd like to integrate it. Or, if you clean it all up, i'll pull and verify that it's all squeaky clean. This took me about an hour to hack through and get running, while helping the kids with homework, so it's notta-bad! Here's what I had to do to get everything building. - clone: https://github.com/ac2cz/FoxTelem - predict4java did not exist in the classpath. * project library pointed to c:\users\chris\desktop\workspace\foxtelem\lib - removed the predict4java Project (since it does not exist in the source tree) * Chris - you indicated this was a custom build, so this was expected :-) - added jar located in /lib/predict4java.jar to libraries * this did not work for me, so I went back on this and just... - clone: https://github.com/davidmoten/predict4java.git\ * edits to SatPos to make it FoxTelem compatible (interface-wise... NOT implementation-wise) - made the isEclipsed function public - added an empty placeholder GetDopplerFrequency method - cloned: https://github.com/davidmoten/guava-mini.git - to make FoxTelem compiler, I had to... * add placeholder for missing function setCreateddate in FoxTLE * fix getRangeCircle call in MapPanel, since it's expecting an double array, but the call returns a list of positions... just updated the code to use the Position instead instead - Now, it runs! Though functionality will not match a deployed release, due to the placeholder functions implemented above. I'm all hands, let me know if you'd like some help! 73's Joseph Armbruster KJ4JIO > >>

The post-deployment Keps are beginning to age. Reports are that the satellite is running noticeably ahead, and automatic Doppler tuning is not very effective. Space Track has now released 5 objects which can be found in CelesTrak at: http://celestrak.com/NORAD/elements/tle-new.txt They are currently the last ones, 2019-071C through 2019-071G. 2019-071C 1 45113U 19071C 20032.81212060 -.00000378 00000-0 00000+0 0 9997 2 45113 51.6415 303.3594 0012021 285.5472 195.1382 15.32728823 161 2019-071D 1 45114U 19071D 20032.81282501 .00002847 00000-0 10000-3 0 9992 2 45114 51.6392 303.3520 0011297 277.7226 206.9640 15.32814794 160 2019-071E 1 45115U 19071E 20032.80963991 .00002845 00000-0 10000-3 0 9999 2 45115 51.6387 303.3757 0012406 281.6995 185.4556 15.32784999 145 2019-071F 1 45116U 19071F 20032.80232506 .03379048 00000-0 92059-1 0 9998 2 45116 51.6406 303.4018 0011383 285.9215 141.1777 15.33072316 197 2019-071G 1 45117U 19071G 20032.80952942 .00002863 00000-0 10000-3 0 9995 2 45117 51.6377 303.3690 0010449 296.7674 170.5149 15.32985181 158 They are currently tightly grouped, but running 1-2 minutes ahead of pre-deployment Keps.

FoxTelem bug fix release 1.08y
by Chris Thompson 02 Feb '20

02 Feb '20

If you are looking at the server data from HuskySat then there is a bug that prevents it from being downloaded. This release fixes that. It also prevents a couple of crashes that have been reported. http://amsat.us/FoxTelem/windows/ http://amsat.us/FoxTelem/linux/ http://amsat.us/FoxTelem/mac/ If you know what you are doing, then you only need the jar file and can copy that into your 1.08w installation. 73 Chris -- Chris E.

Spier had served as AMSAT's President since October 2017. Prior to his tenure as President, Spier served as AMSAT's Executive Vice President and Vice President - Educational Relations. He also served as an AMSAT News Service Editor and as a member of the ARISS Education Team. Under the AMSAT bylaws, Executive Vice President Paul Stoetzer, N8HM, assumes the office of President until the next meeting of the Board of Directors. Stoetzer said "I want to thank Joe for his many years of service to AMSAT in a variety of roles. I especially want to recognize his efforts to mark AMSAT's 50th Anniversary with special events at the Dayton Hamvention and AMSAT Symposium. His leadership in bringing together a variety of figures from the history of amateur radio in space in Arlington, VA this past fall helped to make the Symposium a very special event."

She will be feted at their February convention; the award recognizes teachers making outstanding educational contributions. Melissa is an engineering and computer science teacher at Bishop O’Connell High School in Arlington, VA. She led weeks of STEM and radio activities leading up to the school’s 2018 ARISS contact. She heads the school’s engineering and ham radio clubs. At her previous school, she worked with the STMSAT-1 CubeSat project, the first satellite built by elementary school students. She helped staff an ARISS exhibit at the 2019 Space Explorers Education Conference in Houston and will present a workshop there in 2020. At the 2019 Space Port Area Conference for Educators, she received a plaque from the ISS National Lab SSE program citing her “service, commitment, and desire to push the boundaries of STEM Education.” She brings her students to staff some of ARISS's outreach exhibits, such as a 2019 one at the Smithsonian's National Air and Space Museum Steven F. Udvar-Hazy Center. [ANS thanks ARISS for the above information.] -------------------------------------------------------------------- W1ANT Pro Satellite Tracker Announced Heimir, W1ANT announces that the Pro version has no ads and adds some features. Most notably the ability to group the satellites. The groups can then be enabled and only satellites from enabled groups will show up in the satellite overview. Other features include: - Get a list of Amateur Radio satellites visible from your current location in the next 24 hours. - Get an overview over their paths from acquisition to loss of signal (AOS to LOS). - Only passes above the minimum elevation are shown on the list. - Select one of them and get information on their on-board radios. - Select one of their radios and be able to point your phone directly at it so you can easily operate it. - Extra information, i.e. the actual frequencies to use for uplink and downlink is also presented taken the Doppler effect into account. Get full information on the app at the Google Play Store. [ANS thanks Heimir Thor Sverrisson, W1ANT for the above information.] -------------------------------------------------------------------- AMSAT Argentina Drifting APRS Buoy on 145.825 MHz On Thursday, January 30, 2020 at 1400 GMT AMSAT Argentina deployed a drifting buoy on South Atlantic Seas that aims to transmit APRS on the satellite packet frequency of 145.825 MHz. WSPR will also be transmitted. AMSAT Argentina reports the APRS beacon, callsign LU7AA-11, will initially be on Argentina's APRS frequency of 144.930 MHz but will change frequency to 145.825 MHz so that it can be digipeated by the amateur packet radio satellites. The WSPR beacon will run 900 mW on 14095.6 kHz with the call sign LU7AA. Release will be 100 km offshore Mar del Plata coast, seeking east aiming currents/winds. The objective is to track sea currents tracking and HF/VHF/SAT QRPp propagation tests. AMSAT Argentina, LU7AA, will appreciate WSPR stations receiving/reporting 20M.
