[Elecraft] K3 SSB transmit IMD

[Dave G4AON]

Running 100W output on 20m, using the in-built two tone test oscillator, 
I measure the third order products at -30 dB relative to peak (ARRL 
method of measurement) and 5th order at -40 dB.

There was a suggestion the internal two tone test oscillator gives 
better results by some 3dB than can be obtained by feeding an external 
two tone into the K3... That would put the above figures at about the 
same as the ARRL measurements.
