Re: Galaxy dx99v cb radio

Did this problem occur while radio was being operated? or when it was being worked on? or a result of being worked on?

Re: Galaxy dx99v cb radio

I see no one has responded to your question. The reason may be that the information is a bit vague. The are a lot of reasons a radio won't receive. In the Galaxy 99, the mic doesn't have to be connected to receive a signal so that illimates the mic possibilities. I have found that in some of the Galaxys I have worked on, that the if section ( thats the section near the pll chip, has cold solder joints ( broken solder connections to the pc board ). You may want to look real close at the pc side of the board with a magnifing glass and see if you can find any electronic components ( resistors, transistors. etc ) loose. Good Luck

Galaxy dx959 will not receive. Speaker is working. S meter is showing incoming signal.

the over power doides may be blown. you should start there .they should be marked D-1 and D-2. you may want to replace them with diodes of a higher rating.

Will a diesel 360-3 mic ork on a galaxy dx99v

  • Hi, I can help.

  • The Diesel Electronics CB will work but you have to wire it as stated below.

  1. #1 Shield and Black - Ground
  2. #2 Yellow - Audio
  3. #3 White - Transmit
  4. #4 Red - Receive

  • I don't know if anyone before you has re-pined that mic or not so if you just remove that little Philips screw at the mic connector and then give it a quarter turn you can slide the connector out and take a look and compare the wiring. The actual numbering for the pins on the Galaxy 4 pin mic connector is as indicated below in the diagram. As you look at the mic tip make sure the indent on the mic is as it is the diagram.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

Regards, Tony

Galaxy dx99v, bad squeal when I key the mic

Your microphone wires may be shorted take the mic plug apart (small screws) Now check for frayed wires touching or twisted together!
With the wires being resolderd or taped apart put back together
with the U pointing downward you shout have :
Right corner bottom Sheild ground!
Left corner bottom Black recive
Right corner top White or yellow this is Audio wire
Left corner top RED Transmit or PTT wire

If wiring looks good the problem is in the Mic take to servicer!

I got a dx99v cb it turns on but its not transmitting or receiveing the needle barely moves.

You may have a bad regulator transistor.
