There are a number of updates and improvements to M760's since this radio
first came out. First Microair radios were real crap..no question, I in fact
refused to offer these after testing the first models but the company has as
is fairly well known changed hands also and the latest "Q" revision is
really an excellent radio, and even most earlier 2nd generation on radios
have been made to be quite good with the updates and modifications. I
recently pulled one form a glider we bought, it was essentially
non-functional, sent it in and had a total of 7 changes and updates
completed and now it is a newborn....night and day difference...Just make
sure you send yours to a shop that really knows these radios..I have seen
some really botched repairs from other shops but in the USA there is no one
better than Erie Aviation http://www.erieaviation.com/ (I in fact helped get
them set-up with Microair to be THE ONLY APPROVED US warranty center for
Micoair.)

Oddly, the A14's transmissions were receive just fine by the A4's.

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?
