Narco MK12D

[MrSid]

I have a very loud roar from my radio. It appears some of the connections from the Cessna the radios are incorrect. We have a least two wires that are 12 VDC coming radio Don’t think that’s correct. Does anyone have a 24 pin, pin out for a Cessna 150H. Thanks

You're a little vague on the description and request. Perhaps what wires from where to where and aircraft serial number may help?

Serial #15069149. We added a 403 Flight Com to a Narco MK12D. Intercom works fine as does the transmit but I can’t hear my self when trans mitting and I can’t receive. We don’t know which connector is audio in without the pin connector print.

FYI: serial number was only only applicable if you were interfacing with Cessna radios which you are not? But try these:
