[Elecraft] Microphone for the K3 questions

[Don Wilhelm]

Gary,

Both those microphones should work well with the K3.  Couple that with 
the fact that you hear things OK in the monitor.
That suggests that there is something else wrong with your K3.  I would 
first check the filter selection for transmit using K3 Utility and make 
certain the actual 2.7 (or 2.8) kHz filter is selected for transmit.
All the rest that I can offer is that one K3 I had a hand in testing 
needed to have the Reference Oscillator re-calibrated because of a 
similar problem - that is worth a try.
If you continue to have problems, contact Elecraft support for 
additional assistance.

73,
