As mentioned earlier, it has already been done. The hope is that Rick, KN6KB will eventually share the routines he developed for SCAMP with other developers of automated software.
 
If you have ever tried out SCAMP you will realize that it is even more of a watchdog than a human operator. A number of times when I would have gone ahead and tried to connect on what superficially appeared to be a clear area, the program would not operate. I would then notice a faint carrier within the passband or other minor signal. It seemed to be able to ignore most QRN.

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.
