Hi
I have used the model 701 hand mike sold by TenTec on the K2. This mike
comes with a 4 pin connector but if you change it to the 8 pin used on the
K2 and add the 5.6K resistor from the +5 volt pin to the AF pin on the front
panel board it works fine. It only costs $28. If you add the bias resistor
most headsets for cell phones should work also if you change the connector
or build an adapter cable with a PTT button. Most dynamic mikes do not have
enough output to properly drive the K2 without a preamplifier. The electrit
capacitor mikes like the TenTec or headsets work fine. The MH2 hand mike
sold by Elecraft has been discontinued. This mike had a electrit element
inside it.

Gang,
Just put the SSB board in my K2 [S/N 4858]. I have tried my Shure 444
with the K2 and seem to have no drive. I think I will try a portable
telephone headset. I will need to get some bias for the mike from the K2
then I'll find out if I have a problem with the SSB board or my old trusty
444.
Would like to hear from those who have used cheap/nonstandard
microphones with the K2.
