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.

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.

Can you turn the rf gain pod up for better receiving


Yes you can turn up VR pot inside to recieve max level but will cause noise to be max too. I don't rightfully remember which one does it but I'll refer you to Defcom cb radio mods for a spec sheet
or Snakedoctors cb radio mods google site. Go to these radio mods sites on Google search and type in radio model. It will tell you what Vr inside to turn up RX of RF gain. Turn up modulation and written instruction if you are handy with solder gun how to change a resistor or cap to make it more sensitive recieve. How to replace final stage and resistors to 1/2 watt size for 6 more watts output and spread coils 1/8 inch apart like a comb for 100% microphone loudness or swing output. say 3 watts to 40 watts output. More windshield wiper swing in meter makes loud voice and extends range with Power final boost. Most people prefer to keep a mobile at around 11 watts swing to 45 watts.(but on generic radio meter will show 2 to 5 watts-its not accurate just a cheap indicator you are forward swing). Even though factory says 4 watts FCC hogwash. They come tuned from Cobra with 11 watts to 14-22 watts.Cobra really peaks them babies so competition doesn't beat them out like new louder radios made by Galaxy 55. Even though law says blah blah (corporations bend it)sales pitch Galaxy very heated with Cobra on the game(rich can do what they want)Galaxy is 20 watts factory with big promise to 40 watts dual finals. So Cobra updated and said "screw it we will break the law too" Now Cobra is loud as ever and offering their own super mod versions and dual final radios with 45 to 65 watts output with ranges on SSB & USB of 1500 miles on a strong good outdoor antenna.

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 cobra 25 ltd classic that I bought from a CB shop it was fixed to have 50 W .you can see all the changes made on it .I have it hooked up with two wips 4 ft 1000 w fire sticks and a power mike it...


either he over tuned it and burned the radio out this can happen just cause a radio transmits 50 watts dosent mean the circuity can handle it and it will burn the radio because of overload. another factor is if you are running high swrs with that kinda out put you will fry it sounds like its getting hot and radios dont work well when they get hot take it to a tech tell him what was done to the radio and what it is doing. you can test the radio by buying a watt modulation meter it will tell you excacley what the radio is putting out I doubt its transmitting 50 watts that is a single final radio unless he modified the final.good luck.

cobra 29 has a 12 watt final, doubt you will be doing 30 watts. 25 if your lucky. Use 18 feet of coax, you will get better broad band.

If the antenna comes with the whip in it already, its been tuned at the factory and you shouldn't change it yet.

If not, half way is okay. It still needs to be tuned on a meter. either the one in the radio or an inline.

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.

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.

Low output power


On the meter you are using, does it mesure Average power or peak envelope power?

This is very important to know when you are measuring.

AVG measures basically your dead key. It usually will very little if at all.

PEP measures your peak output, or swing. Modulation.

So even if you have a radio that has been peaked, on a meter that reads AVG, it will still read around 3 to 4 watts. And, if it has a swing kit in it, it will read even less. A swing kit lowers the dead key it increase modulation. Higher PEP.

For example. I peaked my cobra 29 and it does some where around 22 -25 watts PEP. I have variable power in it as well, but usually run the dead key at 2 watts because I have a linear. The Radio alone, when mesureing on PEP with key up at 2 watts, and then when you talk, swings to about 22 -25 watts.

If I flip the meter to AVG, it stays at 2 watts even with talking.

If you have one of those cheap pyramid meters, etc, they usually only read AVG.

Get a meter from radioshack. They have a fairly decent radio for the money. It reads both PEP and AVG and has SWR as well.

If the radio has been peaked and it has a swing mod, it will most likely be swinging to some where in the 20 watt range.

On a side note. According to FCC regulations, a CB radio is only allowed to transmit with 4 watts of final power. Most times the manufacturer will have it a hair under so that they are leagal.

Basically it is illegal to use a CB that puts out more then 4 Watts.

But its a free for all these days. There is no more funding to the FCC for monitoring CB radio, so they do not want anything to do with it. As long as you don't over do it, have over 50000 watts and terrorize a small community with RF, you can do what you want.

Now a days most cb radio's bought have already been peaked if you got it from a cb shop, or off a website that does it.

148gtl, Taiwan when you modulate the meter swings backwards


In the back is where power mods have been added...It sounds like a swing kit 1/2 watt deadkey to 25 watts which is a powerful modulation exceeding 100%. Its a 220uf capacitor in place of a jumper J1 or J(x) J something in some radios. if you replace the jumper and remove the capacitor 220uf or 470uf one.(near finals it will return to around 4 watt dead key) The result of 4 watts is modulation is flat;where if you adjust it to 2 1/4 watt to say 20 watts it will be very loud and modulation is at 100%.

Question about my cobra 200


no need to increase power output. you can take a radio with 100 watts and a radio with 10 watts that had had a modulation kit installed and the 10 watt radio will out talk the 100 watt radio ALL day long. the best thing to do would to put a mod kit in it and have the dead key cut back to 1/2 watt then put as little amp behind it. with those mods it will be loud and clear. hope that helps
