Have you ever listened on the Winlink and NTS-D frequencies? On 40m at night it is hard to establish any kind of session because of the usage levels. I don't get much of a chance to listen to 20m during the day but based on Winlink traffic loads it would appear that those channels are very busy also. The biggest problem is that the remote operator does NOT sit on the channel waiting for it to clear. That is the whole crux of the hidden transmitter problem. The proposed multi-minute wait process just multiplies the session time requiring even more channels to carry the traffic. > >>>Most ops would quickly learn to recognize "QRL?" in CW.

Nor do I sit there watching the waterfall while I am reading a transmission or compose one to send. My guess is that most ops would never hear or recognize a QRL in a mode different from the one they are using. > It would be much better if the automatic station could respond to a > standard QRL signal during receive periods (wasn't it you that > suggested that to me at some time in the past?). > > >>>Yes, I did; the two techniques are complementary. > I don't agree. I like the ability to actually break into a transmission much better. tim ab0wr Need a Digital mode QSO?
