ISS Dopplers
by crohtun 01 Jul '21

01 Jul '21

My SatPC32 Doppler control is way off and I can’t figure out why. Seems to affect only the ISS. As it approaches, the incoming signal is almost 10kHz high — about where it would be with no Doppler adjustment at all. My Doppler.sqf line readsISS,437800,145990,FM,FM,NOR,0,0,Cross band repeaterand keps are current from nasa.all. I also notice that SatPC32 is off on predicting LOS. I was still copying signals 59 well after LOS had supposedly occurred.???????? RayKN2K Sent from the all new AOL app for iOS

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!

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 29 Jun '21

29 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)
