Ghostrider, you have discovered the "black hole" of CB radio mods and upgrades. The lower the sale price of the radio, the more work is needed to turn up any technical info at all.
Don't let anyone give you a hard time about modding a radio that's, er, "cheap". The fewer knobs it has, the more potential for upgrading it, right?
But here's where the problem arises. Most of the mods out there are worked out by someone who does this stuff for hire. The more-expensive radios get all the attention, because those are the radios a tech's customers want to spend money to modify and upgrade.
And this is where all those mods come from. A tech whose customers asked him to work out and install the mods on their radios. If he's feeling generous, it gets written up and posted on the web.
Just one problem. The low-end radios are not the models that get these requests made. And the techs seldom work them out just for the amusement factor.
Would be very cool if someone teased out the details, wrote up the step-by-step and posted pictures to go with it.
But it will have to be someone else. Customers don't bring us many of these. More often than not the owner will simply trash it when it breaks.
My starting point for most mods is the radio's schematic diagram. That info may be out there, but it's not in my library. Simply tracking down a schematic for the lowest-price radios can become a whole project by itself.
But this is your biggest barrier for now, a wide information gap. Yes, it can be done, as soon as someone works out the nitty-gritties and chooses to share them on the web.
