Got given a CB radio.. from a trucker... im in the [UK] wanting to put it in my car.. accept the voltage difference... a truck's voltage is about 24-volt's.. compared to a car.. only being 12 volt's.. i've already read on here, about people blowing the CB radio.. because of the wrong voltage... PLEASE help me with what i need... [ send a URL?] :D thankyou.

not really.Many radios come with one built into the meter on the radio. For those with none you will need an external SWR meter. I would recomend a trucker 2000.

First, lets make sure that the unit does transmit. Get a power meter and see how much power it transmits. If no power is being radiated, you need to have a technician check out the unit.
If you have power then pick a less crowded time to test out if anyone can hear you. Other people with more powerful equipments can only be a problem when you are transmitting on the same channel and both of you happen to transmit at the same time all the time. Chances are remote that this is your problem. Good luck. es

first of all ,remove what you put into it and install the original parts back into it. Now see if it still heats up.If it does what is it thats heating up? Check it out,maybe install a different transistor with higher voltage to keep heat down.Could be a transformer in there heating up .Do the logical first then procede to the next step.

sounds like your in good shape if its a 12-14v output.. the things about people blowing up radios is they use 10-30amp fuses and hook them up backwards.. + to ground and ie... make sure to use a 2 - 5 amp fuse for a normal cb.. and go + to + and - to -...

truckers also like it to have 300+ watts,, and don't tell them what you have and see the difference. lol

also the stock mic's are tinny sounding. trade it off for a good power mic like a cobra 75 $17.99 or any type of echo mic $35 i think.. those will make it sound like a big radio.., also check the SWR's !!!!! free at any cb shop to have them checked .. we don't charge unless it needs parts.

Hi Overton2525,

I used to install all these talkback and sound-effect devices in radios for the truckers, and most were so elaborate, that I did it in kit form. You must be pretty handy with soldering, so here we go with a bold little adventure. CB Radio Magazine has a nice inexpensive project that won't take very long to install.
Here's the link to their pages:

Your radio meets all the requirements for this project. Let me know how this Mod works out for you. Thanks.

Regards, Bill

The red light is a warning of antenna mismatch; when you hold the antenna, you are changing the match between the CB's output amplifier and the antenna. Try it with a different antenna or pick up a 'test light' (or test load) for CBs from an electronics dealer, I've also seen them with CB accessories at truck stops. If the test light fires off and the red light on the CB is dark, the antenna you have is junk.

go to cbtrick.com to radio information go to corba radios and you will find the mod for 11 meters.

my only idea is the frequency that Canadians transmit/recieve on is different than us down south (in the USA). I know Europe and the UK use a different frequency range so my guess is that Canada uses a different radio frequency range than the U.S. making you unable to communicate with fellow radio users. You may be able to search the frequency range for Canada vs. the U.S. and see if there's a difference. Hope this helps...and again, it's just a thought.

you need a job that you can travel they work find you just need to travel . now i just came from seattle wa and i ahave one and they work fine it actualy help me when my truck broke down on the road so dont tell me they dont work .I thank haveing one of these is better than a car cb radio lease to you can carry it wear ever you go and conect it to your car or by batter they work well any who have one need to be traveling or working on the road and you have to close to truckers to get answer to get any feed back at lease a mile a way they work in on the instate and the highway so, if you any thing to say about these come on channel 17 i be on that channel in yakima wa and some times on the road or channel 19 ok. see you. handler name jamarhase...
