Hi,

I saw a glider recently with a "ambiance" microphone installed in the
instrument panel (facing the pilot, it only takes a small hole in the
instrument panel).

I was wondering how this performed compared to what we're used to = goosneck
microphone on the cockpit side.
I like the idea, it's saving space, and you have one thing less in the way
when getting in/out of the glider.

Has anyone been using an ambiance microphone in the instrument panel (or
somewhere else) ?
Any etra noise ? How does it perform ? Is that acceptable ? Can others hear
you correctly ?
Do you have to shout or speak normally ?

We had one in a DG202 we had about 7 years ago. It worked quite well
until the glider was destroyed in an accident.

We replaced it about 6 months late, the new one now has a boon
microphone. On a trip to Feshie, I met a radio engineer who gave me a
circuit for a voice operated microphone. Unfortunately this used a chip
which is now obsolete, so I never built it.

The boom mic is sort of OK. The stalk needs a Viagra injection, and you
need the head of the mic. very close to your lips.

Hope that helps
