Microair Mic Problem

I have a MicroAir 760 for 5 years in my glider and another club member
before me
Never problems

We have a Microair in our glider. It has never worked properly in
spite of a round-trip to Oz. We have given up on it, and now use hand
helds.

Cheers anyway, Charles

I keep hearing of problems with Microair radios, but mine worked
flawlessly for the past six years, or maybe rather 5 as the first year
I was fussing with home built mike system. No problems since I got the
Microair boom mike.

The only "problem" I ever experienced is related to battery. As the
battery goes down you reach a point that you receive just fine, but
there is no transmission. I cannot compare sensitivity to battery
charge of Microair radio to others, but I bet it is not significantly
different.

In case o significant problems, first thing I'd check is antenna
connection and antenna tuning.

There were four MicroAir radios in our club. Two that
were in club ships have been replaced with Becker radios.
They just gave problems, even after going back to
Oz for repair.

One in a private ship will be replaced soon, but I'm
not sure what with.

I have one in my ship. It's been back to Down Under
once. It still works, but from time to time, the transmit
will become garbled. We found out when that happens
to turn the radio off and back on again and it seems
to clear up.

By the way, does anyone know where I can buy a microphone
foam muff? The local music store wants about $4.50
for these $0.37 items!

I can relate. We have one in an L23 that's just taking
panel space. It's
been back to Oz too.

Check the type of fuse(s) used between the battery terminals and the radio.

On my first glider it took me months to realize that I had a slow blowing
fuse that dropped the voltage about 0.5 volts and made transmission
scratchy.

My name (mrsoaring) has been used re Microair boom mics I notice

I made about 1800 boom mics and about 1/2 of those were sold thru Microair
but for the past 12 months they have made their own.

The original mic (mine) was electret. Their new mics are amplified dynamic
mics using aluminum fill. I once used aluminum fill - big mistake as it
work hardens and springy. For the last 1000 or so mics they have been brass
fill (11mm diameter) If you have one of those springy mics then best
contact me direct and will do something for you (guess 3+ years old).

I now make amplified dynamic which work with Microair, Xcom Icom Terra etc
Genave Terra and a dynamic only for Becker Dittel etc

Setting up in field I adj gain so it works well 1 or 2 cm from lips but does
not work well when 10 to 15cm away. I listen on another radio 30m away.
This is essential in open cockpit aircraft such as Tigermoth and open
ultralights

I am no longer listed as a Microair dealer on their web site but all I say
is never take no from Microair till they get it right!! They do not like
low voltage - I recommend use of 16g aircraft wire especially in big 2
seaters like ASH25. -18g is OK for single seaters - I recommend dual
batteries and a good switch to use is C&K7211 with bat1 bat2 and OFF. Also
be careful with voltage loss across those glass fuses -contacts can play up.

Please fee free to contact me off line - go thru mrsoaring.com site
