SatPC32 issues
by Burns Fisher 11 Dec '15

11 Dec '15

I've been using SatPC32 for several years, and have not seen this problem until recently. I'm wondering if anyone else has? After running for several hours or maybe a day or 2, SatPC32 just stops. It is marked "not responding" and it does not refresh the screen when it is exposed. I can not see that it is doing anything. The companion rotor control program appears to be running, but of course when I kill SatPC32 with CTL/ALT/DEL it keeps running, so I also have to kill it manually. First, I'm running this all on a PC with a 4-core Intel I5 processor at 3.something GHz, so power should not be a problem. The unusual thing (slightly) is that the system is "headless". It has a graphics processor, but there is no monitor on it. I use Remote Desktop to access it. That should not make any difference but... On this PC, I am running SatPC32 which is driving an AMSAT rotor controller via a USB serial port, a TS2000 (often not turned on) via a built in serial port, and SDR# via DDE. FoxTelem is running and listening to SDR# via virtual audio cable. Sometimes the AO73 app is also running, but not always. If anyone has suggestions as to how to debug this (what info to collect and send, other stuff to try, etc) I'd be happy to give it a try. Thanks and 73, Burns Fisher W2BFJ

I have an old ICOM IC-706 for the uplink, a Yaesu FT-857D for the downlink, and a laptop controlling both via CAT. I'm currently only manually tracking with an Arrow but I figure that will be enough for a start. Thanks for the tips, will report back when I've made an attempt. 73 -- J.

On the mid-evening passes the last two nights the transponder has been on but no activity. I am hearing my uplink fairly well. 73, Jack, W3TMZ
