How to tell if a frequency is digital

[blackcloud08]

Hi, been out of the scanner business for years but when I look up the counties how can I tell if they're digital or not? Thanks in advance for all the help.

One of the columns of information for each system listed in the RadioReference database is "mode."

"A" represents analog, "D" represents digital, and "E" indicates the channel / talkgroup is encrypted atleast some of the time.

Pull up the FCC License
Emission Designator - The RadioReference Wiki

Is using the RRDB
If it lists PL Tones - it is Analog
If it lists DPL Tones - it is Analog
If it lists NAC Codes - it is P25

Under Trunking
A = Analog
D = P25 (Digital)
E = Encrypted

As for DMR - Sorry, out of luck using a Scanner Alone.

Ok, I see the correct 'mode' in the talk groups of some counties. What if a county doesn't let me see the talk groups?

What specific system are we talking about?
If the talkgroups are known and listed then anyone should be able to view them.
