Usign an Icom IC-SM6 Microphone with a K-2

[W. H. Phinizy]

My K-2 is #999 and I recently acquired an Icom IC-SM6 that I would like
to use with it. I saw an old e-mail requesting an SM6 schematic because
to op wanted to rewire the SM6 to fit his K-2.

My request is not as exotic; I merely want to know how to jumper the K-2
to work with the SM6.

Any help gratefully accepted.

Thanks,

Bill,

You can find the schematic for that microphone at
http://www.dxzone.com/cgi-bin/dir/jump2.cgi?ID=15509.
Pin 1 is AF, pin 7 is AF Ground, pin 5 is PTT and pin 6 is PTT ground.

So wire the AF labeled pin on the mic configuration header to pin 1, and
wire the pin labled PTT to the pin labeled pin 5.
Pin 6 should be wired to GND and also pin 7 wired to GND.

You will also need bias to the microphone to provide power.  Wire the +5
pin to pin 4, and then connect a resistor at the back of the mic jack
between pins 4 and 1.  A resistor between 5.6k and 10k should work fine.

73,
