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.

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.
