Talked to a retired Navy radio guy at the hangar last Thursday and it changed how I troubleshoot

I was working on a comm panel that kept giving me a weird static on channel 2. This older guy came by to grab a tool and asked what I was doing. He said I should check the ground strap first before looking at the module itself. I always start with the module because that is where the problem usually is. But he told me in the Navy, they learned that 60 percent of radio issues come from bad grounds, not the actual radios. I tested the ground strap and sure enough, it was corroded at the connection point. Replaced it and the static went away clean. Now I always check grounding first on any radio problem. Has anyone else run into a simple ground fix saving hours of work?

And that Navy guy was totally right, I had a similar thing with a VHF radio where I swapped the whole unit before a buddy was like "did you check the antenna ground?" and it was just a loose screw.

Oh man, the antenna ground is always the last thing you think about lol. Was this a permanent install or a portable setup? I've spent way too many hours chasing gremlins on a boat where the mast ground plate was just corroded to hell. Ended up cleaning it with a wire brush and dielectric grease and boom, crystal clear reception. Makes you wonder how many perfectly good radios got tossed because of something dumb like that. Have you ever had a similar save where the fix was embarrassingly simple?
