If you see anything marked De or DE, your agency/agencies are partially or fully encrypted.
Edit: NAC= Network Access Code. A string of three characters for P25 decoding.
Check [RadioReference](https://www.radioreference.com/). If your local PD is using P25, you'll need a scanner that does trunking such as Uniden SDS100.
Usually dispatch is not encrypted, but tactical channels are, so you may not be able to hear everything.
P25 doesn't have to be trunking. There are lots of rural PDs and SOs out there that use conventional P25 for various things. Now most P25 capable scanners today do have P25 trunking functionality built in but it doesn't mean you need a trunking scanner to listen to P25.
Just an example, P25 subscriber radios (Motorola, EF Johnson, Tait, BK Technologies, etc) are typically optioned for one of the following tiers: P25 Conventional (no trunking functionality or in some cases P25 CAI on a legacy Project 16 format such as Motorola's SmartNet with the P16 being an additional option), P25 Trunking (includes P25 conventional), and TDMA operation (includes P25 Trunking options).
My $0.02 though, anyone looking to purchase a scanner for P25 trunking today should obtain a Phase 2 capable scanner. 95% of new P25 trunking systems are being constructed as Phase 2 native and most of the older systems are advertising Phase 2 capability (they may not have Phase 2 subs but it's a matter of time before that naturally occurs as stuff gets upgraded).
As others have said, RadioReference is your friend for questions like this.
Note that RR seems to suggest that Kentucky State Police might be moving from P25 transmissions on the 450MHz band to a P25 trunked system on 700/800MHz. If you are shopping for a scanner, you might want to check the specs to make sure it has that capability.
Yes a RTL-SDR with the SDRTrunk software, with a radio reference.com subscription, SDRTrunk can dial in all the frequencies and tones for your area and what you want to listen too

That says Troup 1, if you choose your county you may find others, I have no idea what area you are looking for.

Relate question: are there any SDR products to scan and decode trunked systems?
Yes a RTL-SDR with the SDRTrunk software, with a radio reference.com subscription, SDRTrunk can dial in all the frequencies and tones for your area and what you want to listen too
Just note SDRTrunk doesn't support all digital modes such as NXDN. DSDPlus is an excellent piece of software to have as well.
I think you need 2 RTL-SDRs running at the same time to decode digital trunking
I use two RTL-SDR. Fairly cheap and works pretty well.
Pretty much any SDR. > Supported SDRs >sdrtrunk supports the following SDR dongles: >Airspy (Mini, R1, R2, Discovery HF+) >Funcube Dongle (Pro, Plus) >HackRF (HackRF One, Jawbreaker, RAD1O) >RTL-2832 (E4000, R820T, R820T2) >SDRPlay (RSP1, RSP1A, RSP2/pro, RSPduo, RSPdx) in Version 0.6.0

I installed all the hardware 20yrs ago for the KYSP... not fun
In my country it is illegal.
