Merlin, I believe a thorough filter alignment using Spectrogram to see the de-modulated audio spectrum will straighten things around for you. It is CAL FIL that you need to run, not CAL PLL,
If you are not familiar with using Spectrogram for the K2 filter alignment, take a look at my webpage http://w3fpr.qrpradio.com ot the mirror at http://home.earthlink.net/~w3fpr - look on the left sidebar for the K2 Dila Calibration article - it gives information about accurately setting the K2 reference oscillator and Step 3 provides details on how to use Spectrogram for aligning the filters. 73, Don W3FPR > -----Original Message----- > > My K2 (2631) with KSB2 doesn't transmit and receive on the same > frequency. > There's about a 70Hz difference on lower sideband and 50Hz on > upper.
