[Elecraft] Rear Panel Mic help ple

[iain macdonnell - N6ML]

Hi Ed,

I used an XLR - to - 1/4" cable that came with another mic, and a 1/4
- 1/8" adapter, for the quick test. Pin 2 on the XLR is connected to
the "tip". and pins 1 and 3 are both connected to the shield.

I don't know about the Flex - if it's really TRS, then maybe the Flex
has a balanced mic input? The K3 input is unbalanced ("mono"
connector),

73,

    ~iain / N6ML
