[Elecraft] K2 MDS numbers off

[Don Wilhelm]

  Brian,

Your K2 seems to be somewhat deaf based on your MDS measurements.
I would recommend that you do the steps in the K2 manual under Receiver 
Signal Tracing to identify the failing stage.  Once the failure point is 
identified, we can offer additional assistance.
