interesting problem with a cobra 29

[mr_fx]

the radio is a friend of mine's. He bought it pretty much new. I did a quick peak and tune for him. It sounded great according to the locals, HOWEVER 2 months after the peak and tune people said they could barely hear him. He sent it to me and it's doing about 5 watts dead key and swings to a little under 20 (PEP) (which is what it did when I sent it back to him) but sure enough people say it is quiet, muffled and almost like it's in a tunnel or something. yet I have another cobra 29 sitting here that does 4.5 DK and 15 swing and people say it's loud as the day is long.

I have not yet sat down with it, but I have a few ideas. Just wondering if anyone has any quick things I should check before I get started, just trying to save myself some work... after all this is FREE work for a friend. Well he did promise me a couple beers if I get it figured out.

I'd double check on the solder side of the board for any bad/cold solder joints... I'm almost thinking it's off frequency, and that's why it tends to sound quiet/muffled. I've ran into 29's in the past that came to me muffled sounding, and it ended up it was off-frequency due to a bad solder joint.

Resolder ANYTHING that looks like it could be suspect, and double check your work. If it's right on frequency, next thing I'd check is the mic, if you haven't done so already. Good luck!

the off frequency idea is had crossed my mind... I guess I could hook it up to the counter and know for sure
