Is there anyway to prevent the frequency changing when tuning on the K3 VFO? I noted this is possible when using a P3, does this use software built into the P3 or does it send commands back to the K3?
It uses capabilities built into the P3. Specifically, in "fix tune" mode, the P3 changes its center frequency to compensate for changes in the K3 VFO frequency. With the SDR software that implemented a fix tune mode, the FCD+ could do the same thing. *However* the SDR software would need to know the the K3's VFO A frequency, mode and IF Offset (IF; and IS; commands), calculate the IF frequency that corresponded to the desired "fixed frequency" *and* compensate every time the K3 VFO, mode and/or filter shift/width changed. 73, ...

Hi All I have been trying the Funcube PRO + dongle connected to the IF output on the K3. It works fine, displaying sigs in a 180khz passband centered on 8215 EG setting the FCD to 8215 khz & tuning the K3 to 10100 (A RTTY WX stn) this stn is still visible on the FCD display with the K3 is tuned to 10180 khz.
