Blue Ridge Parkway-Updated!

Listeners along the Blue Ridge Parkway in Virginia and North Carolina have started to report that the US Park Police that patrol the BRP have switched over to new P-25 digital repeaters for their patrol operations.

While vacationing in North Carolina I came across at least one new P-25 frequency that appears to be the Blue Ridge Parkway patrols. I heard 172.7250, N120 while traveling from Charlotte to Asheville, NC. They appear to have stopped using their old frequency of 167.1750 MHz that used to be heard all over the area.

Here are a list of the frequencies that have been reported as active along the route of the Blue Ridge Parkway:

172.4500
172.7250
172.7500
173.7625

UPDATE 1: While in Asheville, I believe I heard the BRP Patrols on 172.5000 MHz, N4c5. Also, traffic on 172.7250 MHz was alternating between P-25 and analog while listening on December 27th.
UPDATE 2: The 172.7250 MHz P25 channel has been confirmed as Great Smokey Mountain National Park, not the BRP.
