Panel mounted microphone source?

Hello,

My glider came with a panel mounted microphone and I really like it.
Unfortunately while working on the panel I dropped it today and I
think it got damaged given when I press the PTT I only hear a squeal
now. I will check the wiring this weekend, but in case I need to
replace it does anyone know where I could get one?

The manual (if you call the one page instruction sheet that came with
it!) refers to it as "Sailplane Microphone h8 M2".

Any suggestions?

Happy New Year everyone!

There is a supplier of panel microphones in Germany that has regular ads
on segeflug.de. Try this link:

I would very much appreciate input from others whom have had experience
with panel mounted microphones.

Hi Mike,

I got one in my dg-600. Works great, even under conditions with high ambient
noise levels

I see them for sale regularly on the German Segelflug.de classifieds pages
http://www.segelflug.de/cgi-bin/classifieds/classifieds.cgi - Search for
"einbaumicro"

Cheers,

Thanks Peter and Lars, the links you shared were a great help. I
reached out to the person advertising and got additional information.
I also found out more about the mike I have in the panel and it is an
older model of one that is still in production. I had incorrectly
identified it as "h8 M2" it actually is "ho M2" with an umlaut over
the letter "o". The latest model on sale is "ho M5".

Now the question is which one is a better option. Anyone else has
experience with either of these microphones one way or another?

Hi Morteza
I will be very interested to hear your transmissions this spring/
summer.
If it works well, I will consider to install one too to get rid of the
boom mic.

Is there any technical info about directional sensitivity, noise
cancellation and/or other properties ?

The one linked above is an electret with an amplifier and an
integrated voltage regulators. The gain is adjustable and can be
adjusted for each installation. No noise cancellation and apparently
it has a circle directional characteristic.

The other one (ho M5) is similar (amplified electret) but I don't
believe the amplifier is adjustable. 400-20K frequency response and
600ohm. Don't have any info on its spacial response model.

BTW, I think I found the problem with my mic to be a broken power
lead. I will test it and see how it goes. But looks like now I have a
couple of sources if I need to replace it.

My fix to the old mike didn't work and I ended up ordering one from Mike Beier (advertised on http://www.segelflug.de/) and finally got a chance to test fly it on a long flight. I am very happy to report it worked perfectly. As part of my 6 hour flight I talked to three different approach controllers as well as many other gliders and everyone reported the quality of audio to be excellent. I highly recommend these.

Now the interesting question is why we don't see more gliders use the panel mounted mikes? It seems to be the perfect solution given there is no clutter with the boom mike and you just speak normally to your panel. No more bending your neck to get close to the mike!

Good question! What model did you end up buying, and how much did it
cost? I'd love to get rid of the boom mic!

I like the idea, but I'm curious about making things work with a
self-launcher.

Don't start the engine? :) I think this is not an option for motor gliders, gliders that have a lot of potential electrical noise, and ones that have a noisy cockpit in general.
