Hi Lyle, Thanks for your reply. A bit more investigation shows that switching between AFSK A, DATA A, USB or LSB makes no difference as far as the frequency offset is concerned.
What does make a difference is switching between Digital mode and CW/SSB in N1MM... In non Digital Modes the K3 VFO frequency display corresponds exactly with the Bandmap for any K3 mode selected. However, it appears that in the Digital modes N1MM offsets the K3 carrier frequency whilst showing the correct Mark frequency on the Bandmap and MMVARI cursor. Or, I think that is what is happening... My brain hurts ! 73 Stewart G3RXQ On Mon, 09 Feb 2009 07:11:25 -0800, Lyle Johnson wrote: > Hello Stewart! > > Be sure you use the PITCH control to select the tone pair you desire to > use.
