Re: Signal Communications Corp R535 Receiver
Hi Andrew, we like this sort of thing!
Biggles has a good point to look for PLL reference frequency - definitely before touching the CX7925B!! Absolute last resort there.
The reference frequency comes from a crystal - in an oval metal can and with part reference Y2. I have highlighted the location on the main RF board here.
Mostly these have the frequency stamped on the can and are easy to read. See if you can pick up that frequency on another receiver.
