From the Highland Park Fire Dept.:
As part of our dispatch consolidation, the Lake Forest Fire Department in conjunction with the Lake Bluff Fire Department, Highland Park Fire Department, and Glenview Public Safety Dispatching Agency will be moving all radio traffic to the East Shore Fire Network effective Tuesday, January 27, 2015. The system is composed of 3 repeater sites and multiple receiver sites which communicate through T1 lines and microwave signals.
The Lake Bluff water tower site is scheduled to go online in early April but comprehensive testing has shown that the Lake Forest Water Tower site covers the Lake Bluff response area with no problem.

o Lake Bluff Primary (Lake Bluff water tower)
- 151.2125 MHz, PL 7A (192.8Hz) Receive- Pending FCC Approval

Does anyone know if RED Center is still dispatching for Morton Grove, Niles and North Maine? Have not heard them toned out recently on 159.6600.

Does anyone know if these frequencies are correct? I have had all of them programmed into my scanner for about 3 weeks now and haven’t heard anything, including today. I have only heard Highland Park Police traffic on 154.8825. They currently have a working fire right now and I can’t hear any of the radio traffic at all. Anybody know the frequencies besides the ones already posted?

No, what this allows is one input but the simulcasting of the signal. As stated above, “The system is composed of 3 repeater sites and multiple receiver sites.” WHat this means is that a voter (radio system computer) determines which signal is best received then rebroadcasts that signal on all three frequencies. To simulcast on the same transmit frequency requires costly technology to prevent reverberation. The dispatcher hears the input signal from the voter. The companies all hear the output of the repeated regardless of the frequency they are on.
RED Center uses a similar set up on Fire North which has east and west channels and the same with Fire South which also has east and west channels.

So the transmit frequency is all the same but the recieve is different. So does that mean they’re all on different Channels.
