460.100 MHz in Union County

[Analogrules]

I've been having problems monitoring this frequency lately. Normally, it's not used. HOwever, the other night I was hearing, what sounded like P25 or encrypted transmissions on it. Does anyone know if they are using encryption or P25 on this frequency now, or was I just receiving interference?

Also, the other night I noticed a couple of unmarked vehicals, white Crown Vics, cruising around the area with a long (29 - 50 MHz) antenna on their roof. At first, I thought taxi since some of them use the lower band frequencies still, but their cars were unmarked. Since they kept circling around, I figured they possibly could be federal. I also saw them at the train station parking lot earlier, with clearly visable portable radios. Any ideas??? I couldn't close-call anything on my handheld. I figure, if they weren't feds or FCC chasers, then they might have simply been Ham radio operators. I just found it odd, since I never saw them around before.

460.100 was at one time the Union County PD's primary dispatch frequency and also served as the county's crime "hotline" for transmitting crime alerts. UCPD subsequently went to the trunked radio system. County crime alerts are now also transmitted over the county's trunked radio system. They were, for a while, simulcasted over 460.100, however when UCPD moved into their new headquarters the simulcast stopped.

Each county police department is now equipped with a trunked radio and all crime alerts are recieved over this radio. Since the move to the trunked system, activity on 460.100 has been almost non-existant. The county still maintains 460.100 for inter-agency police communications, or mutual aid use.

Many sources still list 460.100 as the county crime "hotline" but this is clearly no longer the case. No alerts are being transmitted over this frequency.

Thanks for the info Chris. Even with the severe windstorm yesterday, it wasn't being used. The repeater is definitely still up though because I hear a morse code identifyer transmitted on it every now and then. I imagine they are only keeping it maintained as a last resort frequency for a major disaster. Same being true for their former 453.050. I still keep them programmed in my scanner, just in case.
