[Elecraft] CONFIG Question

[Ron Wetjen]

Finished building my brand new K3 earlier today and am now at the "Test 
and Calibration" point in the manual.

Radio powers up OK.

When I go into CONFIG the display reads

uC 04.86
FW REV5

Turning VFO B doesn't change the display (and turning VFO A doesn't 
change the frequency).

Checked to make sure the VFO LOCK wasn't engaged ... they weren't.

The knobs and buttons all seem to be working.

Thoughts on what to check?
