These frequencies cover the State College, Pennsylvania / Centre County Region.

Previous version of this page can be found here.
Update - Feb 2019: For many years the Commonwealth of PA has operated a much-maligned, proprietary OpenSky state-wide radio system, and previously-heard services such as State Police and PennDOT have been impossible to monitor. As of 2019 things are changing as the State moves to a standard P25 Phase II digital system. Not much heard in Centre County as of early 2019, but we will continue to follow the progress. More info here

While much of the local public service traffic is on the Centre County P25 digital trunked systems. As I monitor and verify frequencies, I will add them to this page.


Local Public Safety - P25 Phase I Digital System

 

The public service trunked radio system in Centre County moved to a simulcast P25 Phase I digital radio system with conventional UHF analog simulcast of Fire and EMS dispatchs in 2013 (article here.)

According to RadioReference.com the system consists of a group of transmitters that cover the "outer region" (Mingoville, Bald Eagle, Howard, Kylertown, Pine Glen, Rhodes, Rock Run, Sandy Ridge, and Woodward), a group covering the "Centre region" (Center Hall, Little Flat, Pine Grove Mills, Port Matilda, Pine Hill (Philipsburg), Purdue, and Rattlesnake) and finally one on the Penn State area at the Ford Building on campus. Transmitters in these three regions each operate on a different set of frequencies. Traffic on the Penn State transmitters seems to be limited to campus users while the Centre and outer regions are supposedly carrying similar traffic. I can only pick up the Penn State and Centre towers so cannot verify what is carried on the outer region system.

Center Region Simulcast: 855.7375, 856.9625, 857.4625, 857.9625, 858.4625, 858.7125 (alternate control channel), 858.9625 (alternate control channel), 859.4625 (alternate control channel), 859.7125 (control channel)

Outer Region Simulcast: 854.9875, 855.9625 (alternate control channel), 856.2125 (alternate control channel), 857.2125 (alternate control channel), 859.9625 (control channel)

PSU Ford Bldg: 856.2625, 857.2625 (alternate control channel), 858.2625 (alternate control channel), 859.2625 (control channel), 860.2625 (alternate control channel)

The PSU Ford Building towers are easily heard at my house using an 800 MHz rubber-duck scanner antenna, but in order to reliably decode the Centre region I must use a 900 Mhz home-made yagi antenna pointed at the Pine Grove Mills transmitter site - if I use an omni-directional antenna I get far too much multicast interference. Also, the Centre towers come in best when the antenna is on the second floor of my house - the first floor location doesn't seem to have enough signal. I am using the RadioShack/GRE Pro-197 digital scanner.
