Does anyone know which law enforcment agencies in the Richmond area have radio encryption? I listen to many differnt agencies around me and Im having a hard time telling if its encrypted or not. Trying to program my scanner so it will lock out thoese talk groups and I can listen to what I want. OR does anyone know how to tell if radio traffic is encrypted or not? NOT trying to start a discussion about encryption I just need help in what is and what is not and what it sounds like. Trying to lock out thoes frequencies in my scanner so I can listen to what I want.
What areas are Encrypted OR what does it sound like? NOT a encryption discusion form. Just need help

If you have Uniden those skip it, radioshack, gre, whistlers it comes through.

Henrico, Chesterfield, Richmond, and Hanover are 100% ENC on their law enforcement talkgroups.
As mentioned above, depending on which scanner you have, the encryption may be skipped over altogether without you having to do anything.

If your scanner doesn't skip over it due to the encryption, it will sound just like a non-encrypted digital signal heard on a standard scanner, just digital hash noise. On RF, the signal is the same, encrypted or not it's only when it tries to decode the digital signal will the difference be known. There is a flag in the header that indicates the signal is encrypted but just by listening to the signal you'll never notice that. Your radio will notice since it has to read the header to know what to do with the data stream that follows. This is how scanners that skip over encrypted signals know to skip them and move on. Be aware that this is a simplification but hopefully gives you the answer you were looking for on the "how does it sound" part of your question.
State police dispatch is not currently encrypted but there is some encryption on their tactical talkgroups. Once source is saying that the state police will be 100% encrypted after a future upgrade. Time will tell.
Made a map of the encrypted counties in VA. Let me know if there are any changes to be made.
Great map you can Middlesex county to the list
Which program do you use for this map? I would like to make a similar one with NC with a small legend for major cities.

If its provoice, then I'd say it sounds like Charlie Brown's school teacher talking to the class, except sped up.
Both my Uniden BCS996XT and SDS200 stop scanning on encrypted talk groups for a second or so, and ENC flashes on the screen.
I don't know if there are any EDACS systems with ProVoice still left in Virginia. Those systems are no longer supported by the manufacturer, and generally have been replaced with P25 systems.
https://mapchart.net/usa-counties.html scroll down to "isolate state," choose the state you want. Then choose a color and just start clicking on the counties.
IS there any indication within the RR database a dept, channel is encrypted?
Yes. Under mode or mod it will have an “e” or “E.” A lowercase e is partially encrypted while an uppercase E is fully encrypted. For example:
TGID Mode Alpha Description
1205 TE PD Disp Police Dispatch
or
TGID Mode Alpha Description
1205 Te PD Disp Police Dispatch
or
Frequency Alpha Description Mod
853.4875 APD 1 Police 1 P25E

Thank you kainixon2187
Henry County and Pittsylvania County are both partially encrypted on law. Martinsville City and Danville City are in the clear.

Isn't Caroline County VA SD running full encryption?
Just spend a few weeks chatting with R2D2 and you should be in fine shape.
