I tried my Lightspeed QFR-XCc's out today in a 152 Aerobat...first

My CFI noticed I had a lot of cockpit noise on my voice during
intercom action. It was like the mic gain was too high.

Charlie,

I have no experience with the Lightspeeds, but a couple of things are
worth checking out. There may be a gain adjustment on the mic. If so,
a local avionics shop should be able to adjust it properly, or you can,
with an appropriate small screwdriver. But first, make sure you're
speaking into the correct side of the mic. It could be turned
backwards, in which case you are speaking into the "noise cancelling"
side, and the cockpit noise is going into the "voice" side.

Happy Flying!
