[TenTec] OMNI VII and Heil Pro Headset.

[Ernie Piche N1SW]

I was fortunate last Christmas to received a Heil Pro headset which is 
very nice.  Heres the problem!  I attempted to use it on the OMNI VII 
only to find out that I can't use the PTT cable with the rig.  As soon 
as you plug the PTT cable into the radio it goes into transmit.  OK, 
before anyone asks, yes I have checked the wiring!  I had to build an 
interface cable so I could use the mic/headset with the omni mic 
connector.  I have tried various configurations of connections for the 
ground leads and still no success.  Soooooooooooo  I had to make an 
external PTT switch connection to the mic jack and it works fine.  Also 
my D 104 works fine.

Before I contact Heil, has anyone else had this situation come up?

Thanks
