I suspect this is an issue of MixW not correctly interpreting the information received from the K3. When in Data modes, the frequency reported by the K3 will vary depending on which data sub mode is in use.
Data Default sub-mode sideband Reported frequency FSK D LSB RTTY MARK AFSK A LSB RTTY MARK DATA A USB USB/LSB "CARRIER" frequency PSK D USB RF frequency (carrier +/- 1 KHz) MixW assumes data modes from the K2 are LSB (there is no separate K3 driver). The firmware "error" prior to the new beta caused MixW to get the sideband right for Data A by chance. Mix W's K2 setting assumes that the CAT data represents VFO frequency (or carrier) instead of 'MARK' as the K3 reports. If you use FSK D and AFSK A with a "standard" 2125 Hz Mark, set the Digi "Cat correction" to -2125. If you are using FSK D, set "FSK center fq" to 2210 [(2125 + 2295)/2] ... if you are using AFSK A, check "AFSK in place of FSK" With Data A, Im afraid that the author of MixW will need to create a new K3 driver that assumes USB operation in data modes. Ideally, before then Wayne will have time to implement separate "mode" get/set commands (on the list) for the digital submodes (FSK D: MD6;/MD9;, AFSK A: MD8;/MDC;, and DATA A: MDA;/MDD;) so MixW (and other digital software) can tell which mode is being used from the IF; response. Then when the authors of MixW (and other software) do K3 specific support they will be able to properly need to do a K3 setting to reflect carrier vs. RF and sideband for each of the digital sub-modes. 73, ...
