Aviation headset with M802?

Well, that's of the title of the thread so, that's kind of the point.

How are you going to hear if someone is trying contacting you, if it is plugged in? A question not a snipe.

Simply pull the 'phone' jack out when you aren't using the headset....

Pics....
How it looks on my 718...

Wiring of mic socket on 718 left and 801 right

schematic of hm36 mic for use with 718.

Not qualified to comment on what is involved with aviation stuff....

It’s on its way back soon.

I'd be curious what Icon would recommend. They make products for both markets.

Plugging a headset into the 802 does not turn off the speaker. That is done with a separate button combo. So it is possible to have both speaker and headset going at the same time.

Pilot Com has as bunch of adapters. I have used a couple. mostly the ones for ICOM A25.

My wife flys 787s and goes thru headsets (the lightweight kind) every year or so, so I have a bunch to work with. My plane is too loud for them but I use them often on other projects.

They all seem to work.

The Icom A25 is designed to work with a carbon compatible mic (i.e. civil aviation mic), unfortunately the Icom M802 is not designed in the same manner. It is designed to operate with a commercial dynamic mic.

Long ago (30 years?) I built an adapter to use my aviation headset on m ham VHF - worked fine. I did have to provide DC bias to the headset mic, and did so through a potentiometer to adjust the audio level. No idea where it is now, but definitely doable.

Just had another look at the issue.

Your H20-10 uses a M-7A mic https://store.davidclark.com/model-m...hone-09168p-33

If you replace it with a DC-87 Mic, it should work electrically https://store.davidclark.com/model-d...hone-09168p-88

The mic cord connector is physically the same but the mic attachment to the boom isn't. You would need to tape it onto the boom!

You will still need to sort out the PTT and connectors but that is the easy part

The attached sketch should get you in the ball park. The 9V dry cell is simply a 6LR61 battery. The rest is self explanatory.

Adjust the 40K trim resistor for 50 to 100 mV AC when whistling into the aviation headset mic.

Cool! My mic is the M-7A. The foam fell off so I can see the label. I do have a PTT button that I used when renting planes that didn't have an intercom. I still have a portable intercom as well, but I think that just splits and mixes the signals that are already present (i.e. the bias voltage for the mic).

[Coquina]

Check the intercom. Mine worked fine when not plugged into the airplane, so it supplied its own bias voltage.

Hello There.

I found a solution for this using a Heil headset and Heil PPT. This may assist you in some way
The real challenge was to get the correct plug to fit the ICOM mic jack. ICOM simply do not sell this as a part. In the end I found an old mic and cable and cut the mic off.
I have used this solution for a number of years and found it works very well.
Main reason for use is so as not to disturb the off watch if on the radio and also the general noise and crackle of the radio can annoy some of the crew when I am just hunting around nets.

This made me giggle. (Sorry)
It’s the perfect solution to this antsy grandmama making her peace with chugging along at 6 knots at 0msl, instead of at 12,000‘ and 180 kts. She can, somehow, plug her d/cs in and make airplane noises to herself while gently leaving kayaks and rowboats in her shantyboat’s wake..
That would require learning more electronics arcana than I care to know, though. Guess I’ll just have to bloom where I’m planted.
