DC 460MHz New Talkgroups

[tvalenti]

As i was scanning last night I found new talkgroups that wernt listed on RR, they are:

19280
20144
20080
19664

Anyone heard them before? If you have the chance to stumble apon them listen in and see if you can find out what they are used for. Im very interested as they possibly sounded like detectives, but dont wanna put them up on RR until im alittle more firm on my answers. Heard the from Bethesda, MD in Montgomery County. Can anyone provide any help?

Are you using the tone code to keep other systems out?

No, Im currently usign a pro-96. From listening to 20080 last night im absolutly sure thought that its coming from district 6. These are definatly new talkgroups.
