Radio basics

@rabbiporkchop did you ever go back to your thread of the EV 602 mic ? I posted a 2 pictures of a my old Telex 56 and ranger 198 uncovered, opinion please......

 

Ugh, I am correct, my CB is great and has never been scoped

 

I totally disagree with you, i like to know what's going on 20 miles ahead of me....even though i have to put up with lot's of crap whenever i get close to big cities....

Plus whenever on a cross country run i enjoy having contacts all around the world with my radio.

 

There is one way to tune a radio without a scope and I probably shouldn't say it on here but I figured you guys could keep a secret. This works with any brand of radio. The only additional part you will need, can be obtained from Radio Shack--a split-phase tuning reducer. They usually keep them in the back so you'll have to ask for it. Try to get one with a 36 degree offset but if they don't have that, a 35 degree will work.

The first step is to remove both covers of the radio. Using a small pair of side cutters, carefully remove resistors at positions R9 and R10. Then, take a drill bit and carefully widen the holes out to exactly 3/16 inches.

Utilizing two pieces of 10 gauge wire approximately 3 inches long, solder the wires in place where the resistors came out.

Next, look at the lower left hand corner of the circuit board and locate the small black chip with 8 pins. Using a MIG welder with .023 diameter wire on the lowest power setting, weld pins 6, 7 and 8 together.

Now use a couple of self tapping sheet metal screws to attach the tuning reducer to the back of the radio. Connect the red and green wires from the tuning reducer to pins JP6 and JP7.

Use some wire nuts to attach a lamp cord to the power connector. This baby is going to be pushing some watts now, so we'll need all the voltage we can get.

Plug the radio into any available wall socket, turn it on and ask for a radio check.

 

When you're westbound coming up on exit 216, the next exit after that is 202, and there's a 12 mile backup that you'll hit at 208, I'll be getting off at 216, because I have a confirmed 26+ mile range, and you won't hear my warning because I'm a mile ahead of you.

Good luck with that.

 

Glad to see that there are some who know something about radio on here. Anyone want to explain to me why some say you need 18 feet of transmission line /coax for a CB ?

 

Question for you radio gurus. Can any one recommend a shop thats worth a crap to fix this ranger rci-6300f on I75 between Cincinnati ohio and ft myers florida?
