Really the only thing you can do to the radio is make sure it is aligned, and that it is receiving on frequency. Although this unit has a frequency counter that will tell you where it's receiving, you cannot successfully put the radio on frequency unless you fully align the radio. In order to align a radio you need a volt meter, watt meter that reads avg watts, and an oscilloscope.

A volt meter and watt meter is easy to come by, however the oscilloscope is an expensive piece of equipment to attain.

You can just as easily tune your clarifier to the correct receiving frequency on the counter.

An easier way to improve your receive on any radio is to make sure the antenna is tuned for best SWR. When an antenna is tuned to the proper length for the best SWR your receive will get better because your antenna will be on Que.

There is also a Schottky diode upgrade that can be done. This consists of changing the detector diodes in the radio to schottky diodes as well as changing a transistor. This mod improves receive in most galaxy radio a great deal.

You can get these as a kit with full instructions on ebay fairly cheap.

You need to replace diodes D1, D2, D23, D24 with the schottky diodes in the kit, then replace TR-17, with the transistor that comes in the kit. Then remove TR-14. and them remove TR-19, and put the transistor from TR-14 in the TR-19 spot.

The Transitor that goes into TR-17 is a 2sc2999. I can't remeber what the Schottky part number is. But like I said, they sell the kits with complete instructions on ebay.

Here you will find all the technical information about your radio, as well as alignment guides.

Here is a link to ebay with an upgrade kit and instructions on ebay.

How do i peak and tune my galaxy dx 55v


Rather than turning it up ,buy yourself a small 200 watt linier and connect it to your radio.That way if you don't like the way it sounds just take off the box and sell it .Your radio remains the same.

Get or have someone Set the SWR's on your antenna.That is the first thing you should always do before even talking on the radio.. Check the antenna.
--------
You will need an SWR meter to check your antenna. FIRST.
I would find help at a local cb shop.. They SHOULDN"T CHARGE to help you SET the swr. only if you need a part or something ..
I don't charge to SET SWR"s .. only if the cust needs a insulating washer or another antenna, or new coax, so-239 etc... I would be glad to help you.. let me know if we can -- CB Shop Temple, TX

Hello Heidi, if you are not receiving very good, make sure you have good clean grounds to start with. Also have you checked your SWR ? What kind of antenna and where is it mounted on your pickup? You may need to relocate the mounting position. Let me know what you have and we can make adjustments.

I have a Galaxy DX 55v cb radio...The problem I am having is that when I key the mic the radio does key up but will not modulate.I have tried several different mic's...I also have trouble receiving but if...


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.

How do u turn up a galaxy dx55v.


Hi, my name is John. Welcome to FixYa. Take off the cover, with the circuit side down, take a plastic tuning tool, you can get one at your local electronics store. turn your channel select to midway of the band. make sure your modulation is turned off. Key your mic and tune VR13 to the Maximum on the watt meter. this is for the power. Next, locate VR14 turn the modulation up, and say ahhhhhhhhh, repeat if needed. Thanks for choosing FixYa....John
