The Bridger Telemetry Communications System provides Frequency Modulation (FM), Very High Frequency (VHF), radio equipment in order to transmit digital hydrometeorological data from the Bridger Mountain area north of Bozeman, Montana, to the Electronics Research Laboratory on the campus of Montana State University, Bozeman, Montana. Either a voice or data mode may be used. The voice mode may be used to communicate in both directions over the link for maintenance purposes and in normal operation is very seldom used. The data mode provides for transmission on 171.9 MHz of digital data in one direction only -- from Bridger to ERL. The equipment is entirely 110 volt AC operated at the ERL end of the link and at the Bridger Data Center. The ridge transmitter is operated from a 12 volt car battery which is kept charged from a trickle charger. (Author)
