Per DSD, it's running Enhanced Privacy/RC4 too, as of 30 seconds ago. Why? I have no idea. It's usually active on the Perrysburg site only, from my findings at least. I thought, I could be mistaken, but I thought it was running Basic Privacy for a while.
I'd be hard-pressed to believe ECSO would be switching to SaiaNet. They have upgraded a lot of their portable radios from XTS1500's to APX4000's over the past few years, and I've even seen an NX-5300 kicking around that I was told they were testing.
When they converted, they were using their XTS1500's in analog, and were for years. When they upgraded, they didn't fleetwide buy new radios. It was just a programming thing.
