Philadelphia Area Repeater AssociationRemote Receive Site146.160 MHz W3PHL/REAGLEVILLE, PATechnical InformationThe receiver Carrier Operated Relay (COR) keys the transmitter Push-To-Talk (PTT) line. Unlike a normal repeater there is no "hang time" on the COR. The receiver "audio output" is coupled to the transmitter "audio input" through a buffer-amplifier. This audio coupler has a "repeat audio level control" built-in. The receiver is a GE MASTR PRO with a Motorola Micor pre-amp to increase it's rf sensitivity. The transmitter is a GE MASTR II running approx. 5 watts. The audio coupler is from a GE repeater panel. The receive antenna is a Hustler G-6, mounted about 35 feet in the air, and gives an omni-directional receive pattern. The transmit antenna is a six-element UHF yagi, mounted about 20 feet in the air, and is pointed at the Worcester site. The remote package runs on +12 VDC which is supplied by the County's +12 VDC/Battery Back-up System. This assures that we should have un-interupted operation even during a power outage. Our host at this site is the Montgomery County RACES organization.
