Soar Truckee where I am based has Microair radios in their fleet of 4
ride gliders. They get used frequently and to the best of my
recollection they have not experienced any problems. I have a 2 year
old Becker radio and transponder in my glider. The radio will need to
be sent to the factory because of low modulation even after trying
several mics and turning up the user adjustable gain level in the
radio. The first time I turned on the transponder when it was
installed by a Becker distributor it started to smoke from behind the
display. The code selector switch, which I thought was a low voltage
device, melted and was rendered unusable. Becker replaced the
transponder quickly. Given the relatively high rate of problems in
glider avionics in general, my preference would be for the company
that provides the best repair service.
