PSP has and uses frequencies across the VHF-High, UHF, 700 MHz, and 800 MHz spectrum. In fact, they still have some VHF-Low still in use in some areas.
Most recently, they are re-building the VHF-High system.
I saw a lot of PSP Channels today in the FCC database. Just renewing old frequencies? Most are licensed for "state-wide" use.
State Correctional Facilities. Granted, not PSP now that I think about it. I think PSP still has some 42 MHz frequencies licensed.
PSP has no lowband equipment. Also, the DOC statewide lowband is being replaced by STARNET. Do you hear traffic on the DOC lowband channel? They've got 800 radios in any transport vehicles I see.
I've heard activity there within the past couple years, and activity on UHF in the past couple months (haven't listened to LB all that often recently).
Oh, and I said above it wasn't PSP.
I notice some of the new PSP VHF trunking lost there FB08 after being granted. Now the old VHF channels just got rebanding for trunking few days ago. Also notice new channels for UHF being added along with Harrisburg farm show getting new channels and PL codes
while patrolling I84 in the Milford/Westfall/Matamoras area at the NY border, which is the busiest section of the Interstate in the county. That's unacceptable that the engineers couldn't even get the coverage for the Interstate figured out, and transmitting on mobile radios no less.
I just ran a quick search of the ULS for YE licenses in Pike County, and for what it's worth there are 9 sites and 13 base frequencies licensed under 8 call signs within the county's borders.
As far as the interoperability issue, those VHF mobiles in the troop cars are really the only way they can communicate directly with local law enforcement in Pike County. .
