[Elecraft] P3: new unit no workee

[Ralph Parker]

New P3, assembled last night.
Basic display is Ok - IF information from K3 gets to P3.
Freq. info does not get from the K3 to the P3 (not displayed on center of
screen or at MKR A:).
Unable to switch to 'fixed-tune'.
Freq. info does not pass through the P3 from K3 to logging program (via
microHam).
However, freq. info does pass from K3 to logging program if P3 power is off.
Re-examination of cables inside P3 shows all OK.

I assume that the default menu functions should produce a working display.
I need Fred's book.
Meanwhile, any suggestions?
