Finally had a chance to try your method.
First off I used your initial settings above and everything sounded great (BFO=11997200) but the VFO was 1KHz high at 28.4 MHz.
Second I tried your cal method and was able to zero beat it...however....my voice was very shallow (transmitting from my K3's memory).
These are the values that came up:
USB 111995650 (BFO) not good....but why did this happen? This is why is sound so shallow or narrow.
I also noticed that with the KD8CEC Manager I can hit reset and that is the same thing as removing the power (power plug and USB plug). Much easier.
Now do you or anyone else know why I am not getting the correct bandpass setting. If I go to 11997 is sounds terrible with those settings.
