Oddly, the A14's transmissions were receive just fine by the A4's. However, the
tow plane's Microaire reception was "unintelligible".

A little off topic but I too have noticed that the Microaire is picky
about what it receives and some transmissions are unintelligible but
are intelligible with other receivers.

I thought for a long time that the problem was that the Microaire was
designed for 8.33kHz and had a narrower IF passband than needed to
25kHz spacing. The problem could then be caused if a transmitter was
off nominal frequency. I no longer think that is the problem but
don't know what the cause is. I could perhaps be that the Microaire
is far less tolerant of overmodulation than other receivers.

I know mine will receive every tracon, ground, atis, awos, tower
frequency etc I have ever tuned with perfect clarity but some glider
radios are completely unintelligible, and it's always the same ones.

Did anyone experiencing this problem find the reason and a fix?
