There is/was an avionics shop in Erie, PA which services Microair radios.

Agreed on the radio crapping out at low voltage.Â* You could watch the
volt meter, key the mic, and be amazed at the drop.

I’ve recently removed an old intercom and installed a flightcom 403mc used with my quite old microair 760 and rewired the input plug for the radio and seem to have gotten something wrong. The intercom works great, but the radio does not. It recieves and transmitts, however it only revieves scramble and only transmitts scramble. The problem is not with the intercom as I am having the same problem when I byepass the intercom entirely. Radio was working fine before. Any help would be greatly appreciated
Over the years, Microair has had more complaints listed on RAS than any other radio that I can recall. I would strongly advise pilots to buy only those radios that can be serviced in the U.S. - why bother with dealing with a radio that has to be shipped internationally (two ways) to get repaired? And the other brands NEVER seem to require repair!

Microair lists the minimum voltage at 10.7 V. While transmitting, it draws 1.8 A, further dropping the battery voltage; this could be a problem at the end of a long flight if you have a full panel.
