Thanks for all the information. I will listen to the rest of the talkgroups listed as unencrypted to see if I get any activity. I don't usually listen to layer 1 as most of that traffic is encrypted. There are a few talkgroups for FWFD/MedStar that I have some questions about. I'm a bit limited on scanners as this is just a temporary setup. Can someone shed some light on or tell me what these talkgroups are used for: 5410 Fire Multi-Group, 5426 Fire Agency Group, 6806 PD Tactical, 6808 FWFD, FWFD, Medstar. I wouldn't think CareFlite deals much with FWFD as they are fairly close to hospitals but if so, how is coordination done with aircraft and FWFD/MedStar?
