The 911 and Sheriff towers are no longer listed individually because they share the same output PL at each site. They were erroneously listed individually up until a few years ago. The current listing is accurate regarding the output tones for each frequency. If you want to see the physical location of each tower, look at the FCC licenses.
Plattekill PD hasn't been on VHF in decades. They operate on NYCOMCO's MOTOTRBO ConnectPlus system. Before that they were on a UHF LTR system for years.
