":I disagree. Most ops don't *listen* to the data tones on a frequency. I know I don't. 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."
I believe this is the crux of the whole discussion. The failure to listen to a frequency before transmission is the problem. That is why the whole suggestion of the software being fail-safe by not transmitting has come up. Personally, it has gone beyond amateur radio, if one is not sitting there and involved in the transmission/reception of traffic. I worked 30 years on the commercial/government side of telecommunications and that is where this type of transmission belong, not here on the ham bands. Need a Digital mode QSO?
