In 1972 the Coast Guard undertook an ambitious two-year project to install a VHF-FM communications system on the Western Rivers. Completed on schedule, this system became fully operational in July, 1974. From some 30 high-level transmitting/receiving sites, the system provides VHF-FM radiotelephone coverage of the Mississippi and its principal tributary Rivers. For the first time, a commercial towboat pilot or a recreational boater can pick up his radiotelephone any where along these Rivers and contact the Coast Guard. The 30 High-level sites are grouped geographically, and remotely controlled through a network of leased landlines from five Coast Guard communication centers. Two of these control centers are located along the Mississippi River at St. Louis and Memphis. The other three are situated on the Ohio, Missouri, and Tennessee Rivers, respectively. The five control centers are linked by a common teletype circuit, and each control center has a "phone patch" capability.
