[Elecraft] K2 Display OTS - Request Advice . . . . .

[Don Wilhelm]

Ted,

A blank display is quite unusual.  Does "Elecraft" display when the K2 
is powered on?

First check the DC voltage at the anodes of D6 and D7.  In receive D6 
should be near 8 volts while D7 anode should be near zero volts.

If there is voltage at the anode of D7, the K2 is going into transmit.

It may be that there is a bad solder connection somewhere causing the 
display problem.  That could be on any of the K2 boards.
