Fellow Allegro listers,
 
My radio is a Microair 760 Transceiver of Australian make. Compared with what
I do hear through my head set in several other planes I flew with, the background
noise in my Allegro is much more severe.
 
Turning the squelch adjustment on the device does not change anything. I think
I must conclude that the radio is not functioning well and must be repaired.
 
Did anyone of you experience the same problem with this radio? Any comments?

Sorry, I am not familier with this radio, so I can't comment specifically. However, I will say that with any electrical system on a Rotax 912 engine, and especially if one has a radio, one needs to have at least a 22,000 micro-farad capacitor in the electrical system to act as a filter for the AC current noise generated by the rotax engine. You should check, or have someone knowledgable check to see if your engine has this capacitor in the electrical system. If you would like to know where the capacitor is located I can fax you a copy of the Rotax 912 electrical diagram and mark where it should be in the electrical system. Just send me your fax number. If you have a Rotax 912 Installation Manual dated May 1, 2007 the capacitor is shown as item 14 on page 109.

Hello T.J,
Myself Lucy Reddy.As I know the MA-760 should always be turned off, before starting the aircraft to protect the radio from transient voltages. For more information visit the url : http://www.lowcountrysoaring.org/members/aircraft/pw5/microair_760.html.
