John, At one time it was not technically possible for a robot station on semi (or for that matter on fully) automatic, to be able to detect diverse signals in the pass band.
There were some who said it could not be done. Well, it HAS been done. Do you understand this? Your acceptance of this kind of QRM is no longer acceptable to reasonable amateur radio operators who now know that there is this new technology developed by Rick, KN6KB, the current Winlink 2000 programmer. I have personally tested it when he incorporated it into the SCAMP mode and it is superb. Most of us now expect (perhaps demand) that further development with automated digital modes and equipment will include the ability to hold off transmitting until the channel is clear. If this doesn't happen then the best that can be said is that these operations would have to be kept in small subbands, similar to the current fully automatic subbands (that also include the wide band semi-automatic operations). My preference, and I think you will find the preference of an increasing number of hams, is that any automatic operation that has no auto detect for a busy channel should be banned from the amateur radio bands. That is a very reasonable position to take considering the available software technology. 73, Rick, KV9U John Becker wrote: > Lets try the guy 150 miles from you well within your > ring of silence (you can't copy each other if you had to) > listens to the frenquncy (unable to ask if the frequency > is in use on every mode known to man) hears nothing. > brings up the auto station and in doing so QRM's a QSO > on the same frequency that he did not hear. > > Now as I see it that is not the fault of the auto station. > But I know you are going to say that the auto station > *should* be able to tell if it was in use.
