Alright everyone, here's the news...
I monitored this system on 4 separate scanners this entire weekend to ensure that I didn't miss any kind of blips, data or voice traffic. The scanners used were a: Whistler TRX-2, SDS-100, SDS-200, and even and SDR.
For context, this weekend was Family Day weekend which I can ensure you that the city of Niagara Falls was extremely busy. From the attractions (the ones open this time of year), to the hotels, motels, and just normal traffic on the roads.
I wanted to share these results this morning, but unfortunately, I got tied up at work and I wasn't able to do so. Was that good news? Well, it depends on which way you look at it. I did get to scan the system for another 4+ hours... but the results were one in the same. NOTHING!
NOTE: I had this system in my radio as both a conventional and trunked system.
