Default Re: Clansman PRC320 problems

PLL stands for phase locked loop.

Well, I would actually not necessarily rule out feedback right away. I’we also got the VHF little brother of the PRC-320 (Plessey PTR-1851) and it had a bad feedback problem. Try disconnecting the headset/handset/mike and key an ssb transmission using the CW key. Does it still squeak?
