What happened in this section next to the camera flash? Did that cap blow up all over those other components? That cap doesn't look bad. This20241004_122658.jpg radio has other caps that blown but they just dumped on the PC board from the bottom. Or is this one of those sections they covered with glue?20241004_122043.jpg

Dang that corrosive glue! ;) Just scrape/clean what you can off. Don't gotta go overboard but usually I just use my fingernails to scrape off whats on the resistors, and I got some soft wooden picks for the others. By the looks of it, its the Sears Roadtalker SSB radio that is basically a Cobra 146 GTL. :) Last of the SSB rigs from Sears. Before that, they were all Hitachi boards.

I think it's the early '80s model. By Uniden?? It's the non wood grain straight faced SSB.

Yes, good old Sonybond, it's great stuff for the first 20 years and then it turns into something that slowly kills radios as they sit stored away.
Looks like they dribbled a little there.
Go over the whole radio and make sure you get all of it, that stuff will eat traces up and component leads after a while.
The solvent LC posted is great for helping soften it up to clean it off.

I think I have 4 of them total. The one here with me developed an issue where the audio during transmit at peaks sounds distorted. It may be a cap issue since it still has all the originals in it. I might try it again to be sure. Otherwise the radio was fine.
