Will,
I must confess that I nearly threw away my headsets because of poor underst
anding of my own intercoms squelch/volume and headset volume relationship.
The volume knob on my headset was rolled up during storage in its pouch an
d I didn=92t notice. I lowered the volume on my Sigtronics but feedback an
d excessive noise was still present. I have no idea how I missed this simp
le headset volume verses intercom volume relationship during an hour flight
but I was hopping mad and ready to yank my panel when I simply lowered the
volume on the headset, readjusted the intercom volume and all was well. D
uh. I really should put a paint dab on my headset knob to prevent recurren
ce as I am getting more forgetful every day.
Best Regards,
Bud Yerly

Thanks bud
I will also try that if it comes back. I will unplug the whole thing as m
y alt switch is down stream of the vr.
So having done a bit of interweb research lightspeed suggested turning down
the headset volume on the headset volume control if it has one (as opposed
the the control on the radio) and turning down the mic gain. This appear
s to have cured the problem.
How permanent this will remains to be seen.

Will,
Yes it can.
Simply turn off your alternator switch if connected to the C and see if the
noise stops.
If you are wired differently where the regulator is powered continuously an
d only the bus is disconnected by the alternator switch, pull the C out of
the regulator or just unplug the whole regulator and check.
If the noise stops. You are out $170 bucks for a new one.
