Hi Jim
I believe this is where my problem is. The rear mic jack is wired as 
mono (ring is not connected to anything) so it is an unbalanced input. 
Connecting the mic audio(-) to the shield might work. Or an audio 
transformer could be used to convert from balanced to unbalanced ie., 
audio +/- to primary and one leg of secondary to tip and other to 
sleeve. Any thoughts on this?
Others must be using the rear jack. How are they doing it? Contacted 
Heil and they don't have an adapter.
I am mainly a cw op and just don't want the clutter of a mic (or the 
wiring) on the desk.
