Electret Microphone

[Robert C. Crawford]

It looks as though I can use an Icom SM-20 on the K3 by changing the wires
around to match the pin outs of the K3 mic connector.  Is this true?  Has
anyone done it?

Thanks & 73 de,
Bob

Bob-
I use the SM-20 with my K3. Works fine!
I made an adapter cord for use with the K3 so I can still use the mic with my IC-7000.

yesterday I finished a new cable to connect my Icom SM-8 microphone to
the K3. It works good - better than the Yaesu MD-1 and the Kenwood MC-
43S for my taste. The best microphone for DX is the Heil Hc-5 after all.
The SM-8 has two connectors and a switch, so you can use it for 2 different
radios. I changed one cable for the K3. The only problem I have is the up-
down buttons. I don't know how they work in the Icom microphone. There is
only one common wire for up and down, and I think it is probably not
compatible with the K3. Any comment on this would be appreciated.

My  Mic settings for the SM-8 are FPL-BIAS.
For the Heil HC-5 I use RPH.

I found that changing the mic level for the front connector also changes it for
the rear connector. If I may add a wish for future firmware updates, it would
be nice if the K3 could save this setting for each connector. It would be
easier to switch from one microphone to the other. Bias is already stored
seperately.
