When the SP upgraded their equipment years ago they got the ability to repeat. When they were chasing Bucky Phillips all around Western NY a few years ago, when ever they had a spotting they would repeat the car to base frequency of 155.535 out on 155.505. Apparently they would disable the local receiver of where they were transmitting from and repeat any selected receiver site in the troop.
This gave them the ability to repeat at the Zone & Troop level. The only other time I heard the repeat mode
engaged again was when they ran targeted raids with other agencies inside the City of Buffalo. These raids lasted maybe a month and everytime a Trooper needed help the system was turned on.
SP Middletown also uses car-to-car as a dispatch frequency when the 155.535 /154.935 are too busy, or if the troop car isn't getting good reception over those frequencies. They are also known to dispatch over the county's EDACS system on Intersystems.
Most, but not all, SP stations have a base radio. These radios are essentially the mobile Orion/M7100 in a GE-Ericsson-M/A Com-Harris base radio enclosure. Typically are programmed to mimic the mobile radio channel lineup but is only programmed for the specific zone frequencies needed. So you may hear a station call a car on the "car to car" channel; yeah it's a bit of a misnomer in this respect!
Coverage issues may be resolved by a Troop Control Point calling cars on State frequency if the Troop frequency is either busy, a tower is down, or coverage is spotty. You won't hear a TCP call on "car to car" though because their consoles aren't programmed for it. If you're hearing a TCP on a county or non-SP radio system, chances are it's another base radio setup next to the primary radio console.
Thanks. I never realized that. I always thought everything was done off of the consoles. In Orange, I believe SP Middletown has a lot of capabilities not normally used, because they are the rollover 911 center.
I believe they always were. What you are probably thinking of is the backup 911 center, which is operated by Orange County and is used in case of fire/evacuation/tech problems at the main center.
The rollover 911 center is where calls would get sent to if all of the calltaking positions are busy with other calls. Also, the state police is one of the few agencies in the county left with a PSAP system, from when they answered cellular 911 calls.
