The extent and nature of television reception difficulties associated with CB radio transmissions

The Federal Communications Commission's (FCC), Field Operations Bureau (FOB) has released the results of a study on interference with television reception associated with Citizens Band Radio. The report is based on investigation of a random selection of interference complaints received by six FCC field offices -- Baltimore, Buffalo, Kansas City, Norfolk, San Francisco and Seattle -- over a one year period. These complaints were analyzed through technical measurements on the complainant's TV receiver and the CB equipment, as well as through interviews with other residents in the CB operator's neighborhood. The report is unique in that it represents "real-life" television interference situations rather than predictions based on laboratory data. The findings of the study are discussed in this paper in the hope that the empirical data will provide new insight as to the causes of the CB-TV interference problem and will lead to preventative actions by involved parties.
