Stepping in before these rumors of old / expired / outdated / illegal use of channels take hold and grow roots:
The state Office of Parks, Recreation, and Historical Preservation's VHF-Low Band frequencies for the Palisades Interstate Park Commission's New York side...
39.440, 97.4 Palisades Administration
39.880, 97.4 Palisades Parks Talk 1
39.560, 97.4 Palisades Parks Talk 2
37.940, 97.4 Palisades Operations
are NOT expired (WPEX799,810; WQTF208, 209) and, in fact, are quite active. To my understanding, the only State Park Police asset capable of the low band channels is Station 901 (aka "Bear Mountain") for monitoring purposes should a facility or maintenance unit require public safety resources.
The VHF-low band channels are used by the rangers, maintenance and administration to talk among themselves and are only a small part of a complex radio network overlaying the Park Region. The other parts are
- the Rockland PSCS trunked talkgroups, used as detailed in post 13 above,
- the UHF linking system (WQRL742), and
- the legacy VHF-high band repeater that's used by:
== State Park and DEC EnCon Police units out of range of the Rockland PSC system and
==outside agencies (e.g.: volunteer ambulance corps) responding to incidents in PIPC parks/facilities, for coordination purposes.
I hope this helps put to bed some of the inaccurate information being bandied about.
