R-2200B Service Monitor Problems

Post by SonicSounds »

Hello All!

I have a R-2200B service monitor with a few problems. I normally just use this for frequency error, so I have no idea how long this other stuff hasn't worked. I notice that deviation alarm, power meter reading, and actually the deviation reading (period) doesn't work. I have the service manual and have traced the RF power voltage to the analog interface board, where it supposedly gets flipped to a multiplexed signal from what I can tell. Somewhere on that board, I don't think thats happening. Just thought I'd throw it out here and maybe somebody has a few ideas.... I can/will measure anything that would be helpful.......
