I have a galaxy DX 44 that on the AM side after it been on for like 10mins the AM side goes out but the FM side don't

check the am voltage regulator. you should have 12vlts on pin 1 ,4volts on pin 2 ,13 vlts on pin 3 . go to ( CB tricks .com ) its the same board layout as galaxy 44 . http://www.cbtricks.com/radios/superstar/3900/graphics/ss3900_sch.gif if you are looking at the board on solder side ,knobs faceing you ,it is located on top left hand corner ,about 1 inch down you will see the slot cut into the board .if you have vlt on pin2 less than 4vlts or higher than 8vlts its bad.

Have you tried another mic. First guess microphone wire broke or broke solder for audio wire in mic jack at mic cord.

Do you mean the FM Deviation or Detector Adjustment? I haven't found a schematic on the DX29HP yet but it may be the same as the DX33. NO GAURANTEE! The DX 33 has VR5 as the FM Deviation. You'll want to borrow or buy an FM Deviation Meter to adjust that. The FM Detector is L5. You'll need to Connect an AF VTVM or scope to IC2 Pin 7. In FM, Set FM RF Generator to 26.965 MHz (CB Channel 1) and at a level of .5uV deviated 3 KHz with 1KHz audio tone.
Reduce the volume as you need to. AGAIN!!! THE DX29HP MAY NOT BE ANYTHING LIKE THE DX33. If you are not sure, please pay someone to make the adjustments for you. It's a pretty nice little rig.

VR 10 , 11 12 PLUS L40 42,43,AND 44. YOU WILL NEED AN RF POWER METER TO DO THIS. sORRY ABOUT THE CAPS.

check the board maby you have cut or short somthing

I really wish I could help you on here but if you don't have the right equipment then you WILL really mess this radio up.I'd tell you to call Don @ 814-898-1046. He does all the factory repair for Galaxy,Connex and The Generals he's the best tech out there.

The Galaxy DX33HML does not have backlighting. If you mean you have Nitro knobs that don't work, you should take it back to whoever installed them. There is no way to tell how they were wired.

No, the Galaxy DX44V is a single final radio. It is a 1969 transistor (tr43) mounted on the rear chassis in between the RF driver amp transistor (tr44) and the antenna jack.

DX 2517 and DX 2527-
Symptom:Buzzing or motorboating sound in either the transmit or receive.
Problem: TR602 is oscillating
Cure: Replace C602 with a .01uF cap {Cap is located in the power supply board}.
RG 66,99,DX2517 Replace Q54 2SB754 60watt 7A with a higher power 2SB817 100 Watt 12A. Derating of this component will cool operation, provide better voltage stability,decrease wobble, allow voltage increase to 14.5 volts comfortably. (replace 10 volt caps in this section of the radio to a minimum of 16 volts before increasing supply voltage to this level)and provide faster swing rise time, Replace Q37 2SA473 to a 2SA1012-0 or ECG153 this will improve the clarity and volume of the modulation and it will also run a lot cooler.
