TIS, or Travelers Information Stations (also known as Highway Advisory Stations), are low power AM stations that can only be licensed to Federal, State and Municipan government entities. They generally operate with less than 10 watts into a 20' whip antenna mounted on a telephone pole although they must reduce power to meet certain maximum FCC field strength requirements.
The fidelity of these station is limited to an upper audio limit of 3 KHz. That fact, along with the extremely narrow bandwidth of the short antenna often makes for poor audio quality.
530: The Connecticut Dept of Transportation (DOT) has operated a TIS station in East Hartford on this frequency since the early '90s. Originally funded to promote the new High Occupancy Vehicle Lane the station came on the air with the antenna mounted on the roof of a warehouse near Buckland Hills Mall in Manchester. The station's coverage was huge, being audible as far away as Springfield, MA, due to the copper roof providing an excellent ground plane. In the mid '90s the station was moved to the DOT facility on Silver Lane in East Hartford with a telephone pole mounted antenna.
1570: WPII600. The town of Glasbonbury operates a station on this frequency that we believe is operated by the Fire Department.
1610: The Connecticut Dept of Transportation (DOT) has operated a TIS station in Windsor on this frequency since the early '90s. Originally funded to promote the new High Occupancy Vehicle Lane the station came on the air with the antenna mounted on a pole in the DOT facility at I-91, exit 37.
