The 146.88 Repeater Information

Location:  N 41  05.67    W 85  10.82

The 146.88 system is a carrier-access repeater located at the site of WANE-TV on West State Blvd in Fort Wayne. It’s antenna is side mounted at the 600 foot level of the 855 foot tower.

Equipment. The equipment presently in use is a GE Master II commercial solid-state repeater, with a receiver having approximately 0.18 uV sensitivity for 20 db quieting, and a 60 watt output transmitter which produces a maximum effective radiated power of 130 watts from the antenna. The typical usable range to a 10-watt mobile rig is 40 miles

Antenna System. The antenna is a Tri-Band fiberglass-covered collinear, being fed by 7/8 inch foam dielectric, solid aluminum jacketed hard-line. The repeater uses a Phelps-Dodge 6 cavity duplexer to allow simultaneous transmission and reception on a single antenna (full-duplex operation). The duplexer provides under 1 dB of insertion loss while maintaining more than 120 dB of isolation between transmitter and receiver.

Timeout: The "you talked too long" timeout is 90 seconds.

Reset: The system timeout timer resets when the input signal ceases for at least 1 sec, which is indicated by a 15 ms tone burst.

Dropout Delay. The transmitter drops out after an input signal has been absent for 3.5 seconds.

Autopatch. This machine has autopatch - please contact the station manager for information on how to use it.
