As is often the case in engineering, Jose, perfect is the enemy of
good. What Rick KN6KB discovered while developing SCAMP's busy
detector was that he could detect CW, PSK, Pactor, and SSB at an ~80%
confidence level without enormous difficulty. SCAMP beta testers were
amazed by the effectiveness of this first iteration.
Pushing the confidence level from 80% to 100%, however, would take
years -- if its even possible. But a busy detector that works 80% of
the time would cut QRM from unattended automated stations (like
WinLink PMBOs) by a factor of 5!
Your comment that "many think it is simpler than it really is to do
it WELL" is frankly moot; Rick demonstrated two years ago that useful
busy frequency detection was implementable on a PC and soundcard.
