OK, tech guys. How difficult would it be for a soundcard based software application to detect a signal present within ,say, 500 hz of where the waterfall is present . I have NO idea, but would have though the guys bright enough to provide all the wonderful software might have an idea. GEE, in the middle of typing this ..I was watching TF3GC in an Olivia QSO on 14105 and a PACTOR station started right on top of him. Any way, I guess the hard part would be detecting real signals from extraneous noise that the short-wave bands produce. But that noise tends be intermittent on a waterfall's display, so maybe the way a real signal like PSK31 or RTTY can be detected is via the duration of the signal burst.? As I said, I have NO clue.
