Satellite Presentation for YOUR Club
by Clint Bradford 30 Jun '21

30 Jun '21

"I really enjoyed Clint’s presentation last night. The fact that he had taken the time to research and know something about his audience and welcomed interaction made it very informative and enjoyable. This was a refreshing change from many canned YouTube presentations I’ve tried to watch, which were poorly done, fuzzy video or muddy audio, or a badly prepared presenter stumbling his way through, with any valuable info lost along the way. Thanks for hooking this one up.” Think a 90-minute informative and FUN Zoom presentation on getting started working the ham satellites would be appropriate for your club? "Thank you for the very informative presentation ... You have convinced me to try working satellites!” Well, no “arm-twisting” occurs (g). Dates currently lined up for New Hampshire and Central California. Let me know if YOUR club may be interested!

Over 12 OM’s are already eligible for the 20 Gold Award, so only 8 left. The certificates will be issued as soon as 20 winners identified. Many have uploaded data to Satnogs but have not applied for the award on link of above mentioned WEB page which is https://docs.google.com/forms/d/e/1FAIpQLSdCAAKTMtTmARDwrjIE_Coai1WR9b2zUFj… it is still time to do it.

MIR-SAT1 identified as object 48868 - nasabare.txt updated
by Joseph B. Fitzgerald 30 Jun '21

30 Jun '21

From Jean Marc (3B8DU) "Yesterday , after Space-Track published the TLE for both objects 48867 & 48868 I track both (having 2 tracking stations at the QTH) and is was quite obvious that 48868 was MIR-SAT 1. Reconfirmed today during 2 passes, having the chance here to be in the same footprint than the command station and that the bird is axing most of the time its easier, the doppler and point match 100% 48868. " The following are the current TLE: MIR-SAT1 1 48868U 98067SP 21179.69602259 .00013025 00000-0 23878-3 0 9995 2 48868 51.6439 285.7711 0003006 182.6608 177.4342 15.49640979 1031 http://www.amsat.org/tle/current/nasabare.txt has been updated de KM1P Joe

Article on switching polarization by I8CVS
by Alex Sutherland VA3ASE 30 Jun '21

30 Jun '21

I'm looking for an old AMSAT Journal article by Domenico Marini I8CVS titled"Switching Four Polarizations on a 70cm Crossed Yagi." I looked up Domenico to ask directly but learned he is a silent key. If anyone could send me a PDF, or guide me to where I might find an archive it would be greatly appreciated.Also interested in any feedback on mounting yagis in an X-configuration and using horizontal polarity for VHF contesting plus other polarities for satellites. Minikits offers a kit to do the switching, apparently inspired by Domenico's design.73,Alex Sutherland VA3ASE

13 Colonies on Satellite
by Stephan Greene 28 Jun '21

28 Jun '21

The 2021 edition of the annual 13 Colonies special event is July 1, 2021-1300 UTC to July 8, 2021-0400 UTC. This year, a "clean sweep" (working stations in all 13 states that were the original 13 US Colonies) is possible via satellite! Yes, one or more stations in each state have volunteered to be active on the satellites this year. More info on 13 Colonies is at http://www.13colonies.us/ , including information on the exchange, logging, individual state QSLs, and certificates. DXsummit is recommended for spotting, and many of the satellite ops are active on Twitter and self-spot there as well. 73 Steve KS1G (one of the K2B/Virginia activators)

Falconsat-3 reloaded, back in business 27 June 2021
by Mark Hammond 28 Jun '21

28 Jun '21

Hi Folks, Falconsat-3 seems to be good shape, and the reloading of the software went "better than expected." As of 1750utc 27 June 2021, it's back in business and open for use. The digitpeater function is turned ON, so that should be working again, too. Users of Pacsat Ground Station (PSGS) should consider "directory archiving to 0 headers" as a quick trick to clear out the old directory information. After a crash and reload like this, the files start over again at the beginning (like file number 100). Also, you might see your station requesting files that no longer exist. That should eventually clear itself, but you may need to manually tell PSGS to not download the old files you had queued up to get before the crash. The bird was last reloaded like 3.5 years ago! That's an amazing record of stability from an impressive bird. Tilt of the hat to Jim White WD0E who created it... It was an expensive bird when the Air Force developed it, as I recall, and you can see that sometimes you get what you pay for ;) Sorry it wasn't ready for Field Day weekend...just couldn't pull that off. 73, -- Mark L. Hammond [N8MH] AMSAT Director and Command Station

SDR Satellite Dongle
by Kees Van Oosbree 27 Jun '21

27 Jun '21

Hello, Are there any SDR dongles that will do full-duplex on transmit from a radio right next to it? I have a Nesdr SDR, but it desenses with the linear birds and FM birds alike. Thanks! 73 de W0AAE
