Hi Rick, That pretty much echos my experience too...DominoEX at 11 baud seems to be the best compromise for 80/160.
Unless the S/N ratio is pretty high, I have not had the best of results with either CHIP or MT63....when S/N levels are high these modes work very well. As for MIL-STD-188-141A/ALE...still looking for a place I feel comfortable placing a 2000 Hz wide digital signal upon....no issues trying that on 10/6/3, but of course noone will hear me there. Anxious to try it though; I sense alot of work went into it by Patrick. 73, Bill N9DSJ --- In [email protected], KV9U <[EMAIL PROTECTED]> wrote: > > This evening the other station that I have been having a weekly hour > testing session with, met on 160 meters tonight.
