OK, Bill, I had heard it before, and refrained to comment, but this time I suffered it myself.
I decided to change the subject to something more appropiate to what I am referring to. I have been thinking a bit about all this....I am tempted to try to monitor using Multipsk with the soundcard while using my PTC-II, if the frame duration and the SNR allows to identify anything else than the signal of my correspondent. So far I have used Spectran as waterfall monitor the PTC and FDMDV, and Spectran is really very sensitive waterfall display. This matter of the busy detector has been overpreached here, and I have always insisted in the fact that the hidden station does exist, but I also have to insist that there is a human factor that aggravates the situation, caused by some "greedy" PMBO users. Would a succesful busy detector really avoid it? It seems to be a real tough task... 73, Jose, CO2JA -- Bill McLaughlin wrote: > Hello Jose, > You are correct, it does not seem that "attended" stations are always > "listening" stations.
