When some one at a shop says " I don't have the time to look at it." It really means, I haven't the slightest idea even were to begin to try and fix that radio, because I I am not really a tech, and I just sell Peak and Tunes, & snake oil.
I can't really say without looking at the radio and tracing down things, but there is sometimes a problem with a cap in the frequency counter circuit, that causes a buzzing sound.
As for the low modulation, there are too many things that could cause this. It really needs a tech, and your gonna end up paying to have it fixed. I would just call galaxy and talk to a tech, and most likely send it in.
You can look at the caps and look for ones that look damaged, or burnt. Also look for any components leads shorting on other components. If you find something that looks burnt or busted, if you have soldering skills, you can replace it with the same part.
You may solve some of the problems that way. That's the first thing you look at when working on a radio with a problem, the second is looking on the trace side of the board for cold solder joints.
From there its a lot of testing.
