Hi Sharp,
I don't know much about radios, but I do know, to some of us our radio's are our life line to the out side world. Some even say their radio is like a woman, finicky as all get up. I depend on my radio and don't just want any Joe Shmoe working on it. Although from what you say you need done, just about anyone can run new coax and match it up with an SWR meter, and not hurt the radio, unless the match is off. I know alot of guys that say they are good radio doctors,---- BUT -----lets just say they have yet to prove it to me. Another thing to keep in mind, is that there are alot of drivers that buy radios and don't have a clue what they are buying, then let some a-hole work on it to do something as simple as set a match, then hit him with a $100bill. You can run your own coax, then go to a CB shop and have them balance it in for you. If you buy from them, most CB shops will match you up for free. There are a cuple of shops at the truck stops in Toledo, on 280, and 420, but I wouldn't recommend the one called the Stony Ridge CB shop. He is in the Petro. The other is south of him near the R&J Trucking yard, alittle passed the TA, on the east side of the road. Don't know much about him.
As for the power, you have to know what it is you want the power for. Do you want to talk louder (greater modulation), or receive better (variable power, or high drive), or reach out and touch-talk a longer distance,(low drive)? It is important to match the type of power you want with the kind of radio you have. There are some radios that will not work with any kind of power. Then some radios already have power built right into them. Do you want a 250, 350, 500 or so on? In my opinion one of the better power sources would be a Texas Star.
