CP200XLS error SYN UNLK

Post by arlojanis »

I have a CP200XLS VHF that display shows SYN UNLK. Yesterday, I removed circuit board for visual exam. All looked OK. After reassembly, now radio is OK. Any ideas about what is going on?

The synthesizer can't lock likely because the reference oscillator crystal is not running. Chances are, impact damage or a bad solder connection in that area. IF you find a defective crystal, the radio will need alignment if replaced. Poke around in that area and see if you can get the radio to go bad again. Also look at all your shields and ground contact points.
