[Elecraft] mic pin connections

[Don Wilhelm]

Daniel,

I added headphone audio to my microphone jack and you can see my method on
my webpage www.qsl.net/w3fpr.

I am not certain I would want to add 12 VDC to the mic connector.  It is a
safety concern for me to pipe any voltage that is not current limited onto a
cable or connector pin - the current capability could be quite large
depending on where you picked up the voltage inside the K2.  The +5 volts
already on the mic header is not capable of supplying a large current and
should cause no safety concerns.
