[Elecraft] KEY OUT LOOP

[Don Wilhelm]

Shel,

The "signal" at the gate of Q5 is a result of the 7R voltage going to 
zero.  There are many places in the K3 that use that voltage rail for 
power during receive.
Does the receiver work?  If so, there are many devices working properly 
on that 7R voltage rail, and you will have to find out why it is not 
getting to the gate of Q5.
Do a "FIND" in the .pdf of the schematic to see all the references to 7R 
and that should enable you to trace the path.  All the 7R points are 
connected together.

73,
Don W3FPR
