All,
Thanks for all the responses on this thread. I wanted to post an update
for anyone interested, as I've made significant progress towards solving
this noise issue.
The headset is a DC H10-20 that is nearly 30 years old. Around 12 years
ago I installed the Headsets Inc. ANR kit but the mic is original. I'm
not sure if electret mics "wear out" or degrade over time, but I decided
to replace it with a new one, and after some research went with the
Pilot Communications PA-9EHN, designed for high noise environments.
That mic made all the difference. Wind noise only breaks squelch when I
turn my head significantly, and in this environment I can live with
that. The mic was $80 and I plan to buy another one for the pax headset.
Also, and counterintuitively, I removed the leather cover over the foam
and used just the foam cover. Oddly this really improved the resistance
to wind noise. I read this tip online somewhere and tried it- glad I did.
I found a software setting buried deep in the MGL V6 menu that changes
the mic from "VOX" to "HOT." This controls how the mic responds when
the transmit button is pressed. I'm not sure why one would ever use the
"VOX" setting but it was set to it by default. To be clear- this has
nothing to do with the VOX intercom, just the mic setting on transmit.
Anyway, after changing it to HOT, and installing the new mic, I got the
"loud and clear" response from a tower 10 miles away.
So I've solved the two issues that I had- nuisance VOX activation by
wind noise and poor transmit quality, and I now have an acceptably good
intercom/ radio setup without installing an intercom PTT.
At Bob's suggestion I bought one of the el cheapo ($10) throat mics and
played with it. It did show some initial promise but was, well, el
cheapo. The next step would be to order a better model (around $150
with great reviews from the motorcycling crowd.) Because of the success
I've had improving the conventional headset, I've shelved this for now.
Thanks again for all the help.
