Hi all,
Well, I solved the problem I was having with WinSDR by removing and
reinstalling the program. It's been running well now for over 24 hours.
As for the GPS, I am not able to get either WinplotGPS or WinONCORE to
acquire a signal. I tried removing and reinstalling both. I assume that
the GPS board needs to be wired directly to the comm port rather than going
through the A/D board. Since the WinSDR gives a lock, I assume that the
GPS is working properly. I happen to be using Windows 98 on a Gateway 2000
at 200MHz with 48 megs of RAM. Probably should increase the memory.
