[Elecraft] Rewiring an Icom SM-20 for K3

[Phil Hystad]

The recent question on desk mics for the K3 reminded me of a project I need to do.  I want to rewire my SM-20 for use with my K3.  I understand that the K3 has all the features necessary to use the electret style SM-20 mic and all I need to do is rewire the 8-pin mic connector for the K3.

So, my plan is to create a cable, about 2 feet in length with the male/female ends so that I can plug the SM-20 into this cable and then plug the cable into the front panel connector of the K3.  I will switch the wiring of pins to cross wire from the Icom mic pin connections to the K3 pin connections.  Then, I will set the bias and other things necessary on the K3 to make it work.

First -- is there anything wrong with this plan -- I mean, is my only need to make sure that the wiring connections to the pins is correct?

Second -- is there an official name for these mic connectors or is it just 8-pin mic connector that I can order anywhere.

Third -- is there any type of cable that I should use or not use.  Does it need to be shielded?  

Thanks for any help you might be.
