I don't listen to this TG, but after a little research it appears this is Lake County Quad 3 FDs. 3200s are Lake Zurich FD, 3400s are Wauconda Fire District and 3600s are Barrington FD. All dispatched by Lake Zurich, it appears.
Wonder if a change was made to the Lake County simulcast site. The Phase II decode on that TG is WAY better today than it has ever been on my TRX-1... same location, same antenna... night and day compared to Friday the 22nd.
Also, Barrington must have just been added over the weekend... they were still on their old analog Quad 3 frequency dispatched by CenCom as of Friday evening.
They still are dispatching on VHF and I still hear quite a bit of routine traffic on there also. They do switch to Red Firegroud often. Probably like most other FD's who have made the switch to Starcom for primary dispatch they are keeping the VHF patched for paging since many still rely on call back and Paid on Call personnel to cover their undermanning
The red fire ground use is the local fire departments are stuck on the 800 mhz cell phone not working within buildings. Many Northwest Central dispatch units go to red fireground and with the trunked fire ground the transmissions come in nice and clear, no break ups that i see as the others claim.
