[Elecraft] K3 with Kenwood MC-60

[Don Wilhelm]

  Jeff,

Is there any chance that you have an MC-60A instead of the MC-60?  They 
are not the same.
If so, I suggest you set the mic amp switch to OUT and disconnect the 
wire on pin 5 inside the microphone.  If you need the mic preamp either 
use batteries in the mic or connect the wire that was originally 
connected to pin 5 onto pin 6 (Note that the mic preamp will no longer 
work with a Kenwood transceiver).
