Don, Your problem may just be HRD/DM780. I no longer use it, but I do recall it did not handle the K3 Data sub-modes correctly.
I would suggest using AFSK-A sub-mode for RTTY rather than DATA A. It does default to LSB, allows use of the dual-tone filter, and indicates the mark frequency on the dial. MMTTY will work just fine if you want something more simplistic than DM780 for RTTY. 73, Don W3FPR On 4/22/2012 7:59 AM, gold...@charter.net wrote: > Dear Group, > > RTTY is supposted to be LSB and PSK on USB. > > If you have the K3 in DATA A mode does it matter.
