The 443.900 repeater has now been put back into operation as of Mar. 2007 in Noblesville, IN.  It now utilizes a split antenna set-up which combines it with a multi-channel UHF trunking system.  One antenna is used for 7 receivers and another for 7 transmitters.  The receiver antenna is connected via 1 5/8" hard-line to a multi-coupler that feeds all the receivers & the transmit antenna is connected via 7/8" hard-line thru a combiner system for all the transmitters.  The receiver is made from a Uniden business mobile radio board that has been fitted into a 19" rack mount cabinet along with a pre-amp and tone control boards and the transmitter exciter is a Icom business mobile radio.  A Motorola RF amplifier deck completes the package to give us around 110 watts output into the combiner unit.

The repeater transmits a 77.0 Hz CTCSS tone ONLY during an incoming received signal.  No reset tones or ID's will be heard if your radio is setup to decode this tone unless ID happens during a QSO.

This repeater is also a part of our 900 Mhz system providing connectivity of both the 900 repeaters and the 2 remote receiver sites.
