[Elecraft] K3 50MHz tx distortion

[Peter Torry]

My SSB signal on 50 MHz is excessively wide and causing problems for 
other users therefore I am seeking any assistance in curing the problem.

Adjusting the mic gain or the comp level has no effect on signal width.  
The power supply voltage is stable and only varies by 100mV from standby 
to full output.  Examining the signal using the internal 2 tone test 
revealed severe IMD at full output but dramatically cleaned up when the 
power was reduced to 50W ( -3dB from peak).

I would appreciate any guidance on where to look next or if anyone has 
experience of this what effected a cure.
