I had the same problem today 8/08/10 was installing a brand new galaxy dx 949 , i used a car lighter adaptor with positive and negative just to test the radio , wow the static was horrible, i think these radios need to be grounded well and power may need to be direct. am trying new installation in the morning will post results.

Is this In your home or car? If home you are probably next to a power transformer outside your home and its picking up the signal from the leaky power transformer. If its doing it from your car perhaps you need to better ground your system. Antenna should be properly grounded as well as your radio. If this does not work let me know............

Can i use rg6 on my dx 949 radio that i am using as a base?


RG6 Cable is a 75 ohm cable and is generally used in residential settings for UHF/VHF off air antenna, cable & satellite TV signal feed lines.

The transmitter you have - like most CB, Amateur, etc. radios ant associated antennas have 50 ohm outputs and outputs. This is for a reason. Ohm's law says Maximum Power Transfer occurs when Resistance In equals Resistance Out. In order to achieve this, all the components must have matching (or close to it) resistance values. Inserting a 75 Ohm cable in a "balanced" 50 Ohm circuit can cause a mismatch or high SWR. There are ways around this - but it's too deep for here.

Your best bet would be to either try the RG6 and adjust the antenna for lowest SWR, or if unable to get it down to an acceptable value (less than 2:1 is the worst I'd accept - but 1.5:1 is significantly better), purchase a high quality 50 Ohm coaxial cable assembly instead. Good luck!

Trying to find the right size linear amp to hook up to my Galaxy dx 949. I want max in/outputs. tired of being talked over. I have a Golden Eagle 150w amp, but have not connected it


That linear will be good for 100 watts of clean power. It has two MRF455 transistor which are 60 watts a piece. The cb will drive it with the carrier or dead key reduced to about 1.5 to 2 watts but i suggest that you read the linear's power while adjusting dead key not exceeding the 100 watts pep with voice. An NPC mod would be a good addition to get the modulation up with a low dead key.

Before you start the projection make sure you antenna system is in good condition high SWR will smake you linear in a hurry.

In factory condition 949 galaxy with a 3.8 carrier it will drive a 667v TexasStar. It is a low drive linear that will end all disputes as to who has more power. 8 out of 10 birds that escape will die of cancer withiin 72 hrs. Ok could not help myself. I would not suggest that unless you just want to damage other peoples receive. The v is for variable power. Hope this was of help.

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.

Will not transmitt after triple 520 final kit install,will receive fine


rather than use a small linier you decided to break your radio instead . It still sounds like a cold solder point to me .

It powers up....no modulation ...output power..or receive....just static...galaxy dx 949...


Sounds like the PLL may be toast. Either that, or someone has **** with the wrong potentiometers or tuning slugs in the radio, causing to to no longer resonate on the correct freqs.

GALAXY 88 HIGHT STATIC IN THE RECEIVE ..


Hi,

If the antenna for the other properly operating radio is used with the radio with the noise and you are getting the static then we can assume it is the radio. If you hear signals with the static, that is, it does receive communications at the same time, there may be a problem with the noise reduction circuitry, or a defective component(s) in the receiver. Without knowing your experience I would suggest taking to a radio shop.
