...flowing in at the rate of 10,000 a month. Unlike the skilled ham operators, whose higher-powered sets can span oceans and continents, CBers need take no tests or otherwise exhibit a capacity any more technical than the ability to sign their names. What's more, CB radio frequencies are so limited (23 channels, from 26,965 megacycles to 27,255 megacycles) that they must be used on a shared basis, like a telephone party line.

Adequate CB equipment, consisting basically of two transceivers (combination transmitter and receiver) and antenna, is marketed by a long list of reputable manufacturers, including Lafayette, Hammarlund, Halli-crafters, RCA and Heath, averages out at a cost of about $300. A typical, medium-priced transceiver operates on eight crystal-controlled channels providing locked-in transmitting frequencies in much the same manner as pushbuttons work on any radio...

In walkie-talkie form, this is no problem, since these little portable jobs do not carry very far. But come summer, the FCC plans to tighten its rules for owners of the big. multichannel CB...
