FC-347 causes radio's transmit frequency to jump around when plugged in.

I don't understand why anyone would want to install one of these when the radio already has one.

Galaxcy DX 66v freq counter and radio slide up and down 3-5 clicks. Not all the time. Nothing I do seems to help

set your mode for AM with frequency counter reading 26.965 mhz on band E. ( channel 1 ) Now you have to adjust VR 1 for 26.965 mhz if its not reading it already . Now set the counter and the radio to 27.405 mhz ( channel 40 ) check for 27.405 mhz . If its off by .003 to .005 thats really nothing but if its off by .3 to .5 thats when it really off frequency .

I have a Galaxy Dx 66 that has real low audio, squeals for about two minutes when you turn it on an you cant hear anything on the talk back, I took it in to a shop an they said they didnt have time to look...

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.
