There are microphones with built-in amplifiers that can be purchased to increase modulation on rigs that do not have internal adjustments for microphone amplitude. Another approach is to try and find the service manual for your radio and see if it has procedures for setting the modulation.

This should be a typical Midland pinout. If you are using a generic 4 pin mic that is wired to cobra/Uniden, all you have to do is switch pin 1 & 2, then 3 & 4.
Not all mics are color coded the same with their wires.

Buy a magnetic mount CB antenna ($35.00 for a K30 magnet mount cb antenna) and put it on the fridge, or microwave, or a appliance thats heavy in metal (gives good ground) and it'll work fine. A base antenna will be even better though. www.copper.com for antenna's and radios

SOURCE: lookin for info on midland cb 13-830 and 77-824
Both radios are AM only, the 13-830 is 23 channel and the 77-824 is 40 channels. Of the two the older 23 channels is a better radio and is able of more frequencies.
