I have a Mircoaire Rev N radio in my glider, purchased as a "Gllider Kit"
kit with mic, speaker, and wiring harness from Aircraf Spruce. It has
worked fine for me. Folks report my transmissions are clear and strong, as
long as my glider is not pointed straight at them (antenna in trailing edge
of rudder, most of which is carbon fiber). I mentioned it was specifically
a "glider kit" since the modulation has been fine.

Our club has another Mircoaire Rev N in a 1-26 that works fine, but has had
to have the mic gain adjusted.

If battery voltage is gets low, the transmission does seem to get garbled.
I fly with 2 batteries so I can switch a fresh one in late in the day if
needed to get good radio transmission.
