[Elecraft] K2 Low Power Out / Hi Current

[Don Wilhelm]

Jeremy,

Strange problem.

The K2 RF power detector consists of voltage divider R67 and R68 and 
diode D9.  One end of R67 is connected directly to the BNC center 
conductor.  That means your problem is quite a mystery.  Could it be a 
bad coax or a faulty (or not soldered) BNC connector.  The only other 
possibility I can think of is a broken PC trace, but those traces are 
quite large.

If there is not a proper connection to the dummy load, the normal result 
is a HiCur message with the power set to a high level because the K2 is 
operating into an open circuit.

73,
