Mark,
The K3 mic input is *compatible* with Kenwood unpowered dynamic mics,
but that does mean it is the *same*.
If the MFJ DVR is expecting voltage on the mic jack pin 5 (the voltage
pin from Kenwood), it will fail. The Elecraft mic pinout is *almost*
the same as Kenwood - except that the source of +8 volts is on pin 6 for
the Elecraft pinout and pin 5 for the Kenwood.
I don't know if that is your problem, but it is worth investigating.
73,

Anyone here have experience wiring up the MFJ-434B Digital Voice Keyer to a K3?
At one time I had learned the K3 mic plug was the same as Kenwood.
