Connect to a meter. if there is rf power on a watt meter at full wattage. then the am regulator transistor is bad. less than $5 part.

SOURCE: I have a Galaxy DX 55v cb radio...The problem I am

sounds like somebody has tampered inside it , knocking out alignments. There is a resistor and very small transistor near back that controls transmit+receive. I don't know which number resistor it is on your model. I know where it is on Uniden/Cobra models(recommend Cobra 25ltd) Take to Cb shop or service repair place. They may help you. Just buy you a Cobra for cheaper and go with it.

Microphone not working


I think it is safe to say 90% of radio problems are microphone. You get a cheap one when you by just about any radio. I believe you are seeing the meter move but not getting audio from your talkback. No matter remove the mic jack plug from radio. For you particular radio looking at the end of the jack notice the small raised numbers. These female connectors no matter the mic type wired for this radio model has the following wires connected or in your case disconnected. 1-(Ground) 2- (Audio) 3-(Transmit) and 4- (Receive).
A RK56 mic would be my suggestion Astatic 636L the second choice a little cheaper but audio it not a crisp.
Don't waste your money a repairing the mic or buying a diesel or road pro or even a cdl mic like a cdl 56 or that Skythumper they are RoadKing 56 wannabees. Sorry about the rant my point is RK56 is Quality.

Galaxy DX 98VHP meter stopped moving . There is no swr reading, nothing. Even with a seperatye meter atached or a dummy load, the meter on the galxy is not working. Did I lose all power?


You appear to be aware of you antenna system with the separate meter attached so the tells me you dont punish a radio with an high swr. I am just guessing red wire/solder in mic cord at plug given that it is a side mic mic jack.
Stock mic
1- Shield (Ground)
2- Yellow (Audio)
3- Red (Transmit)
4- White (Receive)

My radio shows power but its not transmitting out and shows only5 watts on a meter


Don't rely on that meter. use a good Known external meter to check.. make sure your mode switch is on am... not any other mode. also try a different mic. New mics start --RK56's$38.99/Stock mics$6.99...

Radio stuck in transmit meter needle is slammed all the way to the right as soon as you turn unit on


Have you recently changed mics ? if so it is wired wrong, if not I would check for a shorted wire in the mic connector or the mic itself.

Lost channels in a galaxy 66v cb radio


as far as the transmit frequency changing while you have the mic keyed this is normal, the transmit frequency is a little different than the receive, as far as the lost channels go you need to check the galaxy website and check to see if thier is any fixes listed. if none is listed then you can send the tech's a e-mail and tell them your problem and they will advise you on what to do.
