[Elecraft] CM500

[Igor Kosvin]

I just checked my CM500. It appears that tip and ring are shorted together.

Tom,
I recently bought a CM500 new and it did not include any papers at all
however the headset's wiring reflects a standard used in computer sound
cards. The mic jack/plug is usually wired as follows;
tip- mic signal
ring- bias voltage (optional)
sleeve- ground

Hope this helps.
