K2 microphone question

[oe9fwv]

I am going to finishing the SSB board (with the QRP-Project modification
included) in some days, as soon as the parts I need arrived.
I have several microphones I could use, so maybe you can give me some
advice.
I have one Icom SM-8 microphone - is there a circuit diagram around for this
type of microphone? I read in the manual of the K2 that some information for
microphone jumpering should be on the Elecraft website, but I did not find it
yet.
Then I have a Kenwood hand microphone (from a VHF SSB transceiver),
and a Heil Pro Headset.
I have also read about the good idea to make a plug for each type of
microphone from discarded IDE plugs. (several around here)
Maybe there is a list of microphones with my SM-8 type listed?

Werner:
I went to the ICOM website and did a search on the SM-8 microphone. I
found the IC-718 uses the same mic, so I suggest you download the manual
for the IC-718 and you should find enough info about the microphone and
the connector to get it working on your K2. I don't think there's a
circuit diagram for it, but there is a pin-out for the connector on the
radio and you can figure it out from there. You can do the same for
other mics you may be interested in interfacing with the K2.

73's and good luck,
