The CB industry is overrun with much technical information of dubious origin. Many users, in an attempt to improve performance, expend lots of effort & money, only to be sorely disappointed. The YELLOW BOOK was written to help readers avoid costly errors and acheive optimum performance.
The YELLOW BOOK includes 150 Illustrations; It assumes you know how to solder & are handy with tools like screwdrivers & pliers but haven't had formal classroom electronic theory training. Once you learn the material in this book: you should be able to solve 80% of all CB repair & installation problems with less than $1000 invested in tools & test equipment!

Microphone Wire COLORS: Two leads are easy to identify. One: The shield is the microphone GROUND. Two: The wire with the shield wrapped around it is the AUDIO. (Old American-Made Microphones use white for AUDIO; Import Microphones may use yellow or red or some other color for AUDIO).
To identify the other wires: test with an "ohm-meter." four wire microphones: check between the shield & each unidentified wire to see which connects to the shield in receive & which connects in transmit?
5 wire microphones: experiment to see which wires connect for receive & transmit. The wire that connects to both of the other wires (one in receive & the other in transmit) is "common," the others are "receive" & transmit."
