Thanks, Apostolos, The version of Gpredict (1.3_465) is the latest that was offered with this distro. There appear to be several bugs involved here. I haven't tried force-loading a newer version, or building from source, but generally when things are this far out of date, that process doesn't end well. I did the manual update on the file, and that seems to be working, so I'm good for now. At some point I will need to rebuild the entire system. That may be my winter's project... 73, Greg KO6TH Apostolos Kefalas wrote: > Hello Greg, > > I do not know which version of Gpredict you are using, but I remember > there was a bug in older versions, regarding the update of > transponders.

AO-92: Lack of beacon
by P. Suryono Adisoemarta 18 Sep '20

Dear all, why AO-92 is totally quiet in the past couple of days? Can the beacon be activated so we can keep take a look on its condition, similar with AO-95. 73 de Yono - YD0NXXJakarta, Indonesia

Re: [amsat-bb] AO-7 notes

Low enough that the passband doesn't bounce up and down with each character or syllable, or when there is a minimal amount of frequency distortion on ssb. Some days that’s more or less than other days. Antenna gain also is part of the equation. I said power, I should have said ERP. 73, Drew KO4MA -----Original Message----- From: AMSAT-BB <amsat-bb-bounces(a)amsat.org> On Behalf Of Steve Kristoff via AMSAT-BB Sent: Friday, September 18, 2020 7:26 PM To: AMSAT BB <amsat-bb(a)amsat.org> Subject: Re: [amsat-bb] AO-7 notes Drew, what counts as "low-power" for AO-7?

It should be there. I updated transponders about a day after the repeater went online (I was the one who added the transmitter via SatNogs transmitter submittal). It's listed as "Mode V/U FM - Voice Repeater", and should be the last one listed. --Roy K3RLD > Hi folks, > > Does anyone know if there is a way to update Gpredict's "Transponder" > database for the new ISS cross-band repeater?

Gpredict "Transponder" database update for ISS?
by Greg D 18 Sep '20

18 Sep '20

Hi folks, Does anyone know if there is a way to update Gpredict's "Transponder" database for the new ISS cross-band repeater? The program can download a JSON blobby-thing from the Internet with all the transponders included, but the Mode V/U FM Voice information for the ISS is for the old radio (145.800 up, instead of 145.990). I can temporarily override the setting in the Radio Control screen, but it reverts back to the un-altered information from time to time, which is rather annoying. Thanks, Greg KO6TH

As the local public health situation makes a traditionally tellered count infeasible, I have invited candidates, directors, officers, and a few people local to Northern Virginia who I had planned to invite as tellers to observe my handling of the ballots through a Zoom session I've set up (to the extent my webcam permits--I try to set up to give a good view). The handling involves opening each envelope face down, removing the ballot from the face-down envelope and putting it into a receptacle, and tallying the ballots after all of them within the batch have been placed into the receptacle, meeting the bylaws requirement for a secret ballot. I have conducted two sessions thus far (Wednesday afternoon and Thursday evening). I believe I will be able to finish in one more session. Invited folks from across and without the generally perceived ideological divide have observed one or both sessions in whole and in part, and I appreciate their investment of time to give the confidence that observing the process imparts. The bylaws require an announcement as soon as practicable, and in no event later than September 30. This standard will be met. 73, Brennan Price, N4QX Secretary Radio Amateur Satellite Corporation
