Ken, K3IU, is a master detective as it turns out. My K3 operated FB using
AFSK mode but not on FSK. To make a long story short, we discovered a bent
pin on one of the connectors connecting the front panel to the rest of the
K3. As it turns out, this pin happened to be the one that carries the FSK
signal from the ACC jack to the DSP board. Therefore FSK could not work.
Ken was able to bend the pin back into position and carefully re-mounted the
front panel. Fortunately it was not fatally damaged but replacing the
connector is something I will keep in mind for the next time the rig is
apart. Now I know why it was a bit more difficult to mount the front panel
following the DSP board upgrade than I remembered, hi.
