Need help figuring out a frequency.

[Fishguide]

This is my first post so I hope it is in the right place. In Grand Teton National Park the frequency designated Car to Car is a mobile scene of action radio to radio frequency. It used to be 163.125 analog fm narrow frequency. Last year it was changed. Scanning that frequency yields little but the occasional digital noise. Standing next to park rangers supervising animal jams in the roadway the transmissions have the unmistakable digital voice quality. I have a uniden sds 100 scanner and I have tried scanning it as p 25 digital, which is what the Park secondary frequency is. I have the frequency programmed as 163.125 digital with the nac set to search. No success. I have also tried to close call it, also unsuccessfully. Are there any suggestions? Thanks. Walt

I'd think CC would be the best bet, assuming you'd be in the vicinity quite a bit to catch it.

Thanks for your reply. I have close called it and have gotten no hits. I am thinking it may be encrypted but there is no reason for that. No officer safety or security issues. Basically just traffic and crowd control at animal jams along the Park roadways. Since I am new at the digital side of scanning I am not sure I am covering all the possibilities trying to discover how this frequency is being used.

There is a directive that all federal law enforcement radio must be encrypted at some point in the future. A couple of parks or more have already encrypted their law enforcement nets, example, Grand Canyon. I think there is a park in the eastern U.S. that has encrypted their law enforcement net already. There are safety and security issues, NPS rangers handle more than bears, elk, bison and crowds of people. They are full range law enforcement officers and people inside parks are not always upstanding citizens. That is why they are armed. Any debate on this issue is useless anyway, the directive has been issued. It is going to take many years to comply due to the lousy budgets of the NPS, USFS, BLM and USFWS. They will have to build radio systems with a different channel/frequency for law enforcement. Grand Canyon needed a new radio system and established a law enforcement network as part of that. I think they were the first park to encrypt.

Thanks for your reply. This frequency is not used by the Law Enforcement Rangers. It is used by wildlife management personnel mostly doing traffic control at animal jams along roadways in Grand Teton Park, not law enforcement personnel. The frequencies used by the rangers are not encrypted here or in Yellowstone. There are no security or officer safety issues involved, which is why it would be strange for encryption to be used. This is not a debate on the need for or future of encryption. I am trying to figure out if I am scanning for the frequency properly. Thanks again.

I too am looking for assistance in locating these frequencies. We are currently in GTNP and I did a full scan using a Whistler 1080, with no success. The radios in question are specifically those that are being used by the NPS Wildlife Management group. I have also done a full search in the FCC license database, but cannot find anything. If anybody knows what frequencies are being use by Wildlife Management, please assist.
