Hi Everyone,
I know that I have a few posts on here about various radios. One of them has parts ordered and one of them I am in the step by step process with it. Today I have a Cobra 139XLR that had some PLL mods (extra channels) as well as a strange clarifier mod. I removed the channel and clarifier mod and did the following clarifier mod https://grumpy.proboards.com/thread/7846/unlock-clarifier-uniden-upd858-chip. The radio will align perfectly on AM and LSB but USB will only get to 38.9877XXMHz. So, it only gets to about 300Hz when adjusting CT4. The correct cyrstals are in it and the radio has been re-capped. Any thoughts as to why USB would do this?
Thanks!
