[TenTec] Omni C / Corsair Hssssss.

[Troy Wideman]

I agree with that thought, Reid. I did add a simple filter for the phones; an
old choke in series with the phones (out of a speaker system), added a 5ufd to
ground and dumped most of the hiss. Not the best approach, so when you work up a
solution let us know what works.
