SOURCE: power was reversed now radio keeps bowing fuse and will not come on

Most cb radios have protection diodes that are made to burn out to save the radio in this situation. Usually you can replace them with a rectier diode between 1n4004 and 1n4008. They can be purchased at Radio Shack, or if you need more stuff, you can get them from Parts Express. This unit is the same as a cobra 29. If the pc board layout and numbering is the same, then the protection diode number is D23, which is located in front of the pa speaker jack on the main pcb. If you need more help, feel free to email me at rollincbmods@yahoo.com.

SOURCE: trying wire a superstar dm-452

Hello bubba, the wiring code for the radio is
Mic Wiring
Stock
1- Shield
2- Audio
3- Transmit
4- Receive

Galaxy DC-521S (4 wire)
1- Shield
2- Yellow
3- Red
4- Black

If this is the power /echo mic like it looks to be from the Workman catalog, then I can't remember what the wiring code is for the mic. I do know, that the audio wire has the ground/shield wire wrapped around it.Could be just about any color. Put the shield on pin 1 and the audio wire on pin 2 and all you have left should be 2 more. If you get it backwards, then the radio will key up as soon as you turn it on. You'll have to key it to hear the speaker. Just reverse the 2 on pins 3-4. Hope this helps as it's been over a year since I've seen one. Let me know,,, Mechanic

Hi and welcome to FixYa,

Have you tried VR5? Not much on the mods other than adjusting L8-10 for AM power.

Good luck and thank you for asking FixYa.

Customer has lost his power supply cord. where can he purchase another cord. power cord is three prongs.


  • Hi, I can help.

  • For the Radio Shack TRC-447 this is just a standard 3 PIN DC cord. Many CB's use the same cord and they are interchangeable. Some Cobra, Uniden, Radio Shack use the same cord. Texxcomm is a great place to get parts from.

How to turn the power down uniden pro 520 xl


For this radio you adjust power through coils in the back of the radio. Using a watt meter and a plastic screw driver push coils L201 and L202 together and the power output will decrease. If D203 (modulation limiter) has been removed you can replace that as well. This should get you fixed up. Good luck.

NEED TO KNOW HOW TO FIX A RAIDO UNIDEN GRANT RAIDO NEED TO DETUN MY RAQDIO


Probably VR 10 on that radio. You are not really de-tuning the radio, just reducing the carrier power on AM. If you're driving something else, You may also want to adjust VR 11 for a reduction on SSB

I have a uniden pc68ltw cb radio and it keeps blowing the 2amp in line fuse i tried a 5amp but still blows the fuse.i hooked it into another truck to test it but still blew the fuse. something wrong with...


Hello,

have you been using the uniden pc68ltw cb radio without the fuse blowing before?

If the uniden pc68ltw cb radio has not been blowing fuse before, then might be a problem from the radio. This problem should be a power related problem.

The fuse blowing means there is excess of current. So while your trying to refuse, thicken the wire.

Best regards.

TWO TRANSISTOR IN THE RF OUTPUT STAGES ARE MISSING.....TYPE? CIRCUIT DIAGRAM? PRO 501 XL.THANK YOU


Hola santipatag!
I have found two schematic diagrams that are very close to your radio. one is a lessor model and the next is one that is a bit fancier than yours. I would think the output stages would be about the same with maybe a SWR sense function.
Please email me and I will return the diagrams directly to you..... Here is my email

Uniden 520xl makes humming noise when mike is keyed


if you have a power mic , you might have it turned up to high. next make sure you have a good ground on your antenna. if that is ok and you still have the same problem have the swr checked. this should fix the fm radio noise.
