Were the strident advocates of unattended operation to focus their energy on adding effective busy detectors and some form of universal QRL protocol to their unattended stations, they could rightfully claim that unattended stations were no less polite than any human operated station, and ought have full access to the amateur bands. Its curious that those who complain about "technology jail" show so little interest in engineering a key.
In contrast, peaceful coexistance among wideband digital modes and narrower modes seems difficult even with everyone's best intentions. How do you find 6 khz of unused spectrum within which to call CQ, and how do you deal with the many different collisions that could occur during the course of a QSO? It would make more sense to eliminate the current automatic segments (once busy detectors and universal QRL are widely deployed) and repurpose these segments to encourage experimentation with wider modes. 73, Dave, AA6YQ --- In digitalradio@yahoogroups.com, "larry allen" <[EMAIL PROTECTED]> wrote: > > I am sure, you have heard of the expression...
