[Elecraft] KAT2 unresponsive

[Don Wilhelm]

Bob,

The '--' in the ATU menu means that the KAT2 firmware is not being seen 
by the K2 MCU.

Take a good look at the point where the control cable is attached to the 
KAT2 control board - look for broken wires.
Do the same for the header that plugs to K2 Control Board P4.

Make certain the header which plugs into K2 Control Board P4 is 
installed correctly - the green wire should be at the top.

73,

   tuner was working fine yesterday and earlier today, and then after one
> press of the "Tune" button on the front panel it is no longer functional.
