HDSDR and SDR Play2
by Paul Overn 14 Mar '18

14 Mar '18

Just purchased the SDR Play and using HDSDR for the software. I plan on using this for. FM and Linear sats. I was trying this system out today on the FM sats, and used my D72 to transmit. The sound coming from my HDSDR doesn’t seem as clear as my D72. What are some tips and tricks (settings) in HDSDR to clear up some of the static and other noise. Any hints in general would be appreciated. Thanks. KE0PBR Paul Overn Sent from my iPad

Re: [amsat-bb] AO-91 and circular polarization?
by Todd W Deckard 14 Mar '18

Greetings Jerry, thank you for this (yes I meant AO-92). If I understand, you are saying the the satellite uses a conventional linear antenna. However AO-92 is easy enough to access that a 3db loss from the polarity mismatch b/t linear and circular is not significant. Correct?

Out of the Footprint
by Douglas Tabor 14 Mar '18

14 Mar '18

Will be out of the AMSAT-NA footprint for a month. It’s nothing anyone did, but don’t want folks to be wondering “where did he go”. Have already been making some plans for the 3rd week of April - NE and WY grid corners in particular. Stay tuned. Some great DX happening now and a lot of new ops on - will miss that, but rest assured, I’ll be evangelizing AMSAT and ham radio satellites wherever we go. Vy 73 from Doug, N6UA and Pam, K0ZXZ

1.2 GHz earth to space only: Is that due to FCC regs or is it just the evolved convention? I am also curious to know what equipment satellite operators are using for L band? Red KC4LE

K2BSA/5 on AO-91 this week.
by tjschuessler＠verizon.net 13 Mar '18

13 Mar '18

Jim Wilson, K5ND and myself, N5HYP will be teaching Radio Merit Badge classes at Camp Wisdom, Dallas, TX, EM12 Tuesday, March 13 and Wednesday, March 14th. We will be using the K2BSA/5 call. Our plan is to do one AO-91 pass a day. On Tuesday we will be doing the 19:47Z AOS Western US pass and on Wednesday, the 18:33Z AOS pass favoring the eastern US. We should have 15 scouts with us each time so please give us a call and a shout out to the boys and maybe we will get them to shout back. 73, Tom Schuessler, N5HYP
