Philadelphia Area Repeater Association

Remote Receive Site

146.160 MHz W3PHL/R

EAGLEVILLE, PA



Technical Information

The "remote input" or "link" package is basically a cross-band repeater. It receives on 146.160 MHz and re-transmits on the UHF "link" frequency.

The 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.
