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.
