Ron, We haven't been able to reproduce this (yet).
Are you using the latest beta release (2.82)? It includes a menu entry called CONFIG:AFSK TX. If you set it to FIL ON, you'll have a 400-Hz filter around the RTTY transmit tones. Please try that. It should clean up noise, if that's the issue. I still don't see how DUAL PB could have anything to do with it. When you get a chance, please send me your entire receiver setup. 73, Wayne N6KR On Feb 13, 2009, at 6:41 PM, Ron W3ZV wrote: > I am working the CQ WPX contest. K3 & FL-7000 amp at about 300W.
