Thanks for the info so far.
Regards the sock, the latest DC comes with a foam cover, is that enough?.
Tuk Tuk there's no adjustment for gain on the M-7a Electret mic from what I can see. The gain adjustment you mention is on the Dynamic type mic, so this kind of suggests Dynamic would be better. Have you had a look at the Electret type?
The reason I mention the Dynamic mic and Electret mic is that the DC H10-56 Passive came with Dynamic (probably carbon amplified) and this was built specifically for heli's. Cant seem to get hold of one of these sets either so went down the h10-13.4 route.
Other issue could be the avionics, badly installed maybe. Speech seems clear, and maybe a faint noise that I pickup before start-up
Does anyone know if you can still get h10-56 headsets. I have the option to return the DC H10-13.4's, but not sure if thats the right way to go.
Thanks again
