Zugriffsverletzung error in SatPC32
by kb2m＠arrl.net 09 Oct '15

09 Oct '15

Is anyone seeing the error "Zugriffsverletzung" or (accessviolation) in SatPC32 when they d/l keps? I'm seeing it on two different computers. It started at the same time, a few days ago. I can work out of it by closing and opening SatPC32 and sometime having to replace the standart.sat file in the process. 73 Jeff kb2m

satpc32 rotor display
by Jim White 09 Oct '15

09 Oct '15

Just set up new computer, new GS232, new SatPC32, old G5400B. Managed to get SatPC32 to talk to ServerSDX and get it to talk to the GS232 and calibrated the rotors. Where in SatPC32 or ServerSDX does it show me the current position of the rotors?

There is a 67.0 Hz tone on uplink well.

FOX-1A
by Keith Le Boutillier 09 Oct '15

09 Oct '15

Hi Is the Fox-1A open for use? it was my understanding that it was going to take between 2 days to 2 weeks to commission the new satellite and not to be used during this period. Listening to night the satellite pass starting at 20:24 the satellite is taking a hammering with stations from all over Europe I don't think many if any QSO's took place. 73 Keith GU6EFB

too much information
by Bob- W7LRD 09 Oct '15

09 Oct '15

Hello-With the new Chinese satellites and now Fox. There is a bewildering and confusing amount of information. Fox is also called AO-85 and grace 2. For the "digitally challenged" is there one place where all the basic information Keps, Doppler.sqf etc. Can be found? With "simple" directions, for simple people. On occasion I have inquired to several of you for assistance (thanks Glenn). Wanting to be independent of that process do we have a "watering hole" where we can go. 73 digitally challenged Bob W7LRD

Ignoring the AFC on the uplink receiver, I would program 5 channels, from 10kHz low on approach, to 10kHz high as it leaves, with the 67Hz tone on all of them. 73, Drew KO4MA -----Original Message----- >From: Rick Tejera <saguaroastro(a)cox.net> >Sent: Oct 9, 2015 1:37 PM >To: 'Andrew Glasbrenner' <glasbrenner(a)mindspring.com>, 'AMSAT BB' <amsat-bb(a)amsat.org> >Subject: RE: [amsat-bb] Fox-1A/AO-85 transponder to remain on to 0000Z 10Oct > >Drew, Quick question regarding the 67.hz tone..
