Is it possible to use an ICOM SM20 with the K3 ?
Looking at the K3 manual the mic socket pinouts are different from the SM20 although there is bias available as used in the ICOM electret element. It seems to me that I will need to rewire the SM20 plug. Is there an Icom to K3 mic adaptor or is there any other way to use the SM20 without rewiring the plug. I really don't want to sell the SM20 when I come to sell the PRO3 on purchase of the K3. Seasons greetings and 73 to all.

Unfortunately, Kenwood/Elecraft use pins 2 and 8 for PTT where Icom used 5 and 6. To use the SM20 with the K3 you have two choices: 1) rewire the SM20 plug to move PTT to pin 5 and PTT ground (chassis) to pin 8. 2) make an adapter cable - Foster Male Foster Female Buxcomm CE8 Buxcomm CBC8 1 -------------------- 1 2 -------------------- 5 3 4 5 6 7 --------------------- 7 8 --------------------- 6 73, ...

Don't sell it, just rewire the connector. I don't have the SM20 but I do
have an SM6 that I rewired and it works fine. In the SM6's mic connector I connected the mic audio (white) to pin 1, the PTT (red) to pin2, and the gnd/shield to pin 7. The K2's jumpers were set to the MD2/MH2 configuration with a resistor between pins 1 and 6.
