I just started hearing that here at the stadium on Saturday. It is the LE-4 frequency with the N68F NAC that all the NIFOG federal interop channels are using. And it's been all encrypted...I found one I've never heard in this area. Not sure who it was though.
168.1125 1/27 9:00am P25 and fully ENC.
I have it from the NIFOG as Tac LE 4.
