[Elecraft] K2 No Power Output

[Don Wilhelm]

Murray,

I suggest that you build the RF Probe that was included with the K2 
kit.  The schematic is shown on page 9 of Appendix E along with the 
assembly instructions.
After that, start on Appendix E page 12 - Preparation for Transmitter 
Signal Tracing and follow the steps shown there.

73,
