[Elecraft] KX1 3080 Module High Current & Now No power Out

[Don Wilhelm]

Steve,

Yes, when everything is working properly, you will have 5 volts on pad F 
when on 80 meters.  What is the voltage on pad E when you are on 80 
meters?  Make certain that you have pad E connected to the proper point 
(see KXB3080 manual figure 7).  Pad E is the control, pad F is the output.

73,
