Question about Galaxy Radios DX-44V 40-Channels Base CB Radio

1 Answer

Galaxy dx-44v wont power on

When I got this radio it had roughly .25 watts modulated output. I replaced the final and driver {tr43 & tr44} still little to no output. I took the radio display apart from radio when power switch/volume control shorted on chassis now it wont power on. Need help on this Thanks Kf5msu Derrick

Check near the rear of the radio.. around the power input connection and the audio transformer there should be a 1n4001 diode.. check it for a short. replace it if it is.. and it should power up.. also in the same area check for any shorted traces.. on the circuit side.. also
on the sides of rci main board radios near the bracket screws theres a transistor voltage regulator.. make sure its connected to the board.. sometimes they come loose.

SOURCE: Galaxy Dx-88 HL

anything over 10 amps should be sufficient i would assume. if it calls for a 10 amp fuse anything less than that would be under powering the unit

SOURCE: it powers up....no modulation ...output power..or

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.

SOURCE: refurbished dx 959 from galaxy no modulation? no transmitt?

If there is no transmit at all, it sounds like it wasn't fully refurbished. If it is just low modulation then just turn VR16 and VR14 all the way to the left.

If its not working at all, send it back. It hasn't been refurbished.

Galaxy 44v has no modulation


If its a used radio it could be a number of reasons.If its a new radio it could be half those reasons.. Assuming its a new radio you need to remove the bottom cover and with a copy of the service manual you need to adjust the modulation .

I have a galaxy 44v that recieves keys up but know watts come out i have put new finals new voltage regulators b754 and the one in front of it changed the 300v redish " dog tic" thats what we...


  • The Galaxy 44 has 1 final and 1 voltage regulator not "finals." I doubt it is putting nothing out although it may look like it on a watt meter. Check VR16 (low power adjustment for the amp) and VR 13 (High power adjustment) for the amp in the radio. That radio has a variable power so make sure the pots were not turned out of whack. Check VR 14 as well. this is your AMC modulation pot adjustment.

  • Test the driver as well as the pre-driver. Check your microphone to make sure the wiring is good and the PTT is functioning.

I have a galaxy 44v it transmits on fm but receives on am what can i do to fix this problem


Replace the AM final, then make sure your antenna is tuned to lowest SWR to prevent the final from burning out again.

Quiet Galaxy DX 44V


Sounds like you have lost a final or a driver transistor if so a shop or reputable repairman is your best answer. You should also have him check your cables and SWR on your antenna system as well as check for loose grounds. Sounds like you had a high SWR and blew out a final transistor. But it could be as simple as a loose component or cold solder joint in the radio. Get professional help.

Does the galaxy dx 44 v have dual finals ? thanks


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.
For locations, see the following page:

I have a 77 that has got hardly any swing anymore.it keys 3-4 watts and won't swing past about 8 watts.i used to get 25 watts plus swing out of it. i have replaced the finals and it did not help.any ideas?


Is this just on the AM side or also on SSB?
If you type in 77HML or Galaxy 77HML in your Search Block,you should have a listing for cbtricks.com. and it should say Manual.This will give you Schematics,Transistor Voltages,Parts Placement and Specifications anything you would need is on this page.There are 3 Transistors on the Back Right Corner of the Radio looking at the part side,TR-49 is a predriver for TR-50 and TR-51,which are your AM Modulation Transistors.Hope this helps you out.

Symptom:Buzzing or motorboating sound in either the transmit or receive.

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.

Weak xmit - draws excessive current


Hi and welcome to FixYa,

On your posted description of the problem, initial check would be a possible leak of either the drive transistors(TR44 to TR46) or the finals (TR43 & TR56) for 2004 and up versions. Others to check would be TR55 & TR51.

Good luck and thank you for asking FixYa.
