[Elecraft] CM500 Adapter

[Walter Underwood]

$35 is too much for this mic adapter. It probably reflects the small lot manufacturing cost, but you don’t need to pay that.

This adapter costs $5.45 and does the same thing.

The KX3 mic connection is TRRS, but Ring 2 and Sleeve are both connected to ground. They are labeled mic ground and logic ground, but they are tied together inside the radio, so a TRS plug works just fine. The wiring detail is from the Fred Cady book.
