These are the two they use most often. When they have an emergency situation on ch1 (TG 30366), the other units will continue regular dispatch on ch2 (TG 30367).

I've heard 453.950 (103.5), old NPD 2, used in the last few weeks by what sounds like the Park District. Sometimes you will hear an ISU unit key-up on 458.900 (103.5) which can accidentally activate the 453.950 repeater. I haven't heard anything on 460.025 since NPD switched to Starcom21 in Feb 2006.
Correct. Since the NPD 453.950 and ISU PD 453.900 repeaters are only 0.5 MHz apart and use the same PL tone, sometimes an ISU unit transmitting on 458.900 will activate the repeater on 453.950. I've noticed this happening for a few years now, and it seems to happen most often with the ISU PD radios that transmit the MDC1200 chirp. I believe the bleed-over may be one reason that when NPD switched back to UHF in 2001 they chose to use the 460.025 repeater instead of the 453.950 repeater that they used to use prior to METCOM.
daleduke17: Did you happen to catch which TG NPD used during the 4th of July Fireworks at Fairview Park? I know BPD used ch2 at Miller Park and I also monitored their Park Dist 453.100 (118.8) repeater.
That's cool. Were you listening to the traffic this afternoon/evening after the first sets of storms went through? Sounded like a lot of 10-50's across Normal. They also went into Bloomington to help out a bit.
I didn't catch the storms. I used to listen online frequently when Starcom21 was getting rolling in McLean Co via the streaming audio at www.mcleancountyema.org, but I haven't been tuning in much lately.
