Radio Schematic

Does anyone know where I could obtain a copy of a schematic for an ARC/Cessna RT-328 nav/com transceiver? Got a modulation problem and am quite capable of fixing it (that's my real life) but not without a "roadmap". Thanks for any info! Fly safe!

Re: Radio Schematic

Try calling ESSCO at 877-318-1555 (toll free) and ask them if they have the service manual for the RT-328. It will have the schematics and the component layouts.

Re: Radio Schematic

Thanks Stan. I had forgotten about them...even have their catalog somewhere. I'll give them a call. If it isn't an arm and a leg it would be worth having! Appreciate the help. -Bill

Re: Radio Schematic

Hello Bill,

My RT-328 and yours have the same trouble and like you I can not fix it without schematic. 

Do you have any info about modulation trouble?  Mine work fine in RX but in TX I heard a loud buzz like a feedback.

Thank you and let me know...
