[TenTec] Orion 1 Audio interference

[Bob Cunnings]

I have noticed that as the SUB audio gain is advanced toward maximum,
it begins to have a  significant effect on the level of SPOT tone and
cw sidetone heard in the MAIN receiver. I use headphones with MAIN
receiver audio only selected for both left and right.

I actually take advantage of this behavior - I like my cw sidetone
level to be higher than my SPOT tone level, so I set the SUB receiver
audio gain control to about 75% and then by muting/unmuting the SUB
receiver I can switch between a low SPOT tone level and a much higher
cw sidetone level without the hassle of adjusting the sidetone level
in the usual manner!
