I agree that ... IF ... and, it is a big IF at this point ... that you could prevent the "hidden tx effect," this should solve the problem.
But what about existing modes such as Pactor I, II, and III? Can they do this now? Or would they no longer be welcome on the amateur radio frequencies? What about voice detection? If you are going to operate based on BW, then wouldn't some of the stations migrate to what is currently the voice area here in the U.S. ? Or should there still be a bandplan (not based upon FCC rules, but based on general agreement) that the data digital modes stay in one area and voice in another? Or should all the data modes of the same BW stay together and keep analog signals separate? My concern is that we still won't be able to mix voice (whether analog or digital) with data and image on any given frequency. Right now the only HF band you could do it (but probably go against the current voluntary bandplan) is on 160 meters. 73, Rick, KV9U -----Original Message----- From: Dr. Howard S.
