Bradley,
? Let me see what I can find. This was an X9000 but hardware wise at the point he made the connections the X and the X9000 *should* be the same animal. You will need service manuals for both to pursue the project.
He basicly severed the uC's data/control lines to the synthesizer and injected data calculated by his arduino from info Mike B. shared about the radio's divider/synthesizer operational process.
Again, POC. It would still take a fair amount of designing to hammer out the details and make an operational radio that doesnt resemble an alien autopsy.
