Bad Freq Synth
About 50 years ago I turned a hobby (ham radio) into a living
and worked repairing all kinds of electronics equipment, including 2-way portable radios. Now I'm retired
and can revive an old hobby again. Now I don't have to be pressured into fixing stuff fast and can take my time again.
The old Motorola CP200 that I've been working on programs fine. I downloaded the software from this site and bought a programming cable. The frequency synthesizer doesn't lock and the steering voltage is way off. Either the VCO is bad or the frequency synthesizer chip doesn't work anymore. I was able to remove the chips from the board without doing any damage so my soldering skills are still in good order even considering my advanced age.
Unfortunately I haven't been able to find a place to buy the necessary parts. Anyone have any ideas? I have able to purchase volume controls, channel switches, and other routine repair parts. Maybe I have to be a Motorola dealer. Never did that, but I was a GE two-way radio dealer many, many years ago.
