Hi,

I came across the post below on a Usenet group. I am only a very occasional ISS APRS user, but have noticed several of the regulars here when I do operate. My impression is that it is either largely a non-problem, or better solved through the APRS client. Can anyone suggest a good answer which I can cross post?

============================= I want to somehow disable the PTT on my TX from SatPC32 when the satellite is below the horizon. This is very pertinent to running APRS through ISS. At present I have to be stop my APRS program and restart it manually at the correct times and I keep missing passes. I suspect I would need to use DDE to link to some sort of port control program or maybe via rotor control but am not experienced in using DDE.

Is there any SatPC32 guru who can make some suggestions?

Thanks from Dick G4BBH
