[Elecraft] k2-100

[Don Wilhelm]

Ron,

I would look for a problem in the KPA100 T/R switch area.  Especially be 
suspect of Q6 and Q7, D11, D12, D13 and D14.

While this sounds like a condition when a relay contact is damaged, 
resist that thought because the K2 and KPA100 transmit/receive switching 
does not operate any relays, it is entirely electronic.

When you say you "bypass the antenna around the KPA100" do you mean that 
you attach the antenna to the base K2 *in place of* the KPA100? please 
explain better just how you are accomplishing that.  Is this a KPA100 
mounted externally to the base K2?

73,
Don W3FPR
