MOTORIST AID TRANSCEIVER. VOLUME 2
CB radio, as the Class D. Citizens Radio Service is commonly known, is a vast and growing resource for communication with the travelling public. This report contains the results of a study of CB radio for motorist aid and emergencies--how it is being used, its benefits and problems, and what can be done to improve its effectiveness. The recent phenomenal growth in the popularity of CB has been accompanied by an increase in CB monitoring activities by police and public safety agencies. Full time, complete geographical coverage is still a long way from reality. Although actual emergency calls are fairly rare, it takes a considerable degree of operator attention to sort CB emergency calls from routine messages, noise, skip and extraneous communications. Additional motorist-aid channels are not practical within the limited RF spectrum presently allocated to CB. Digital signalling offers an alternative way of separating emergency and motorist-assistance calls from other traffic. Suggestions for FCC actions and other steps which should make existing and proposed Citizens Radio Services more useful for motorist aid are presented in this report. Design and test data are given for a CB digital adapter which shows the feasibility of low-cost automatic transmitter identification and digital signalling.
