How about using PSK31 as the "baseline" and then transmit any other digital mode a kHz or so up from the highest PSK31 signal that is on at that time?
That is pretty much what I do on 80, 40, and 20. I would very much like a spot frequency to operate on for 30 meters which seems grossly underutilized and is a superb digital band. I like 10.133 for a dial frequency. It clears a high power government digital station by a few kHz, that is frequently on in my reception area, and I like anything with repeating digits:) I wonder if hams do not tend to operate there because they do not have an antenna for that band? On 10 meters, I generally put the dial at 28.120 and on 6 meters at 50.290. I have not done much with other bands except a little bit with 160 around 1.808, but I guess I am a bit high and probably should try 1.805. But I love the number 1808 with my repeating my favorite number twice. As you can see my dial frequency selections are done with great scientific analysis:) My actual transmitting frequency is going to be nominally 1500 Hz above my dial frequency. This will vary for each user depending upon their particular equipment and operating preferences, but I suspect that most will be around 1000 to 1500 Hz higher than their dial frequency. Are there any hams who find that they prefer other center frequencies due to some reason or due to their rigs filtering requirements? 73, Rick, KV9U Andrew J.
