Has anyone had any luck getting decent audio from
the stock electret microphone element in the David
Clark H10-40 Headset? I got decent audio from mine
using my Ten-Tec Paragon, but when I tried it
with a TS-950 it sounded awful (very distorted).
In both cases I was using 12V DC bias with a 1.8K
series resistor, and a 47uF blocking capacitor to
power the electret mic. Any suggestions?

Thanks,

Mike, W4EF
