[Elecraft] K3 Using IC-SM5 Mic

[w0ih]

I'm trying to get my Icom IC-SM5 mic to work with the K3.  I've setup the
"FP:L Bias" on the K3 and there is 4.98 volts on Pin 1 of the K3 mic
connector.  No output from the rig at all (varied the pot on the bottom of
the mic and the rig mic gain).

I would think that 5v should be sufficient for the SM5 mic.

I tried putting in a 1k resistor from pin 6 (8v) to a 2.2uf cap, but then I
just get feedback (full output) into a dummy load.

Anyone have any ideas?

Mike
