They may have abandoned analog for digital since 2020.
Make a few Custom Search ranges in your scanner.
The first: 140 - 144 MHz , the next 148 - 174 MHz and finally 450 - 470 MHz.
Put the Audio Type to Digital Only (if you have the DMR or NXDN upgrade), take note of what you hear. It will flash the Colour Code or the RAN. Push the ENTER button to lock in the Code or RAN. Use replay to listen to the audio you heard to see if it is what you are looking for.
You can leave it on All and hear analog and flash PL or DPL if they still are analog. DMR and NXDN will be noisy in All or Analog Only.
Lastly, if you see the operators nearby, use Close Call and save your hits.
