Bundini,
Which Dav Clark mic did you use. The converter (8 to 150 ohms impedance) I got from Flight Suits.com has a high pitched squeal each time I key the mike. They have tried to resolve that but no joy yet. We are on our third converter.
When you say plugs right in do you mean that the com block on the mask will plug right into the connectors for the mic at its base? Have you had any degradation of the mike over time due to moisture build up in the mask? That was the reason it was recommended that I stayed with the M 101 military mic.
Before you are totally comfortable with your fresh air source please run a CO monitor pickup in the mask during taxi and shut down. Your exposure is definitely less than the rest that are doing nothing except going flying for sure with your current arrangement.
The trumpet was where I was going to pull fresh air from to run the CO scrubber system from. Since there was no interest in that system, the idea was dropped. If there is interest then I will resurrect it.

Oh wonderful One of Socialist State of Mexifornia!
I ran fresh air from back side of air compressor air cooling horn into cockpit where I plug in my MBU-5 oxygen mask for nice cool fresh air from front of aircraft. Used 1" Scat hose. Put brass filter screen where I placed hose onto horn with little 1" flange thingy so I eat no bugs in process. Replace mask mike with mike off David Clark, plugs right in. Its works perfectly, and the funny thing is when I take off the mask in flight for a candy break I can easily smell the odors surrounding me. Brass screen is a must to cut down on air pressure to mask, now it works just like a pressure oxygen mask.
I tried everything else, sealing up all the nooks and cracks, sealing up around the oil cooler, everything, still smoke system smoke in the cockpit! Theres just no way to stop it coming in, or at least none I can figure out. Then if the canopy is cracked open, even more!
Easy with the mask program. No applause, just send money.
