Chicago EMS Digital!

[SCPD]

Wow, Chicago EMS sounds great! What a huge improvment from their old analog system! The only thing is the dispatcher sounds VERY loud and distorted. Why is this? I haven't heard anything on the old analog channels 460.600 and 460.625 for about a week? Are they FULLY switched to the digital radio system?

Also, this is a conventional radio system or trunked? I've heard both. I've head that at first they'll use the repeaters conventional and then when CFD and CPD go digital it will go to a trunking format.

Last Question: Are these repeaters programmed for 0 hang time? After the tranmission the repeater shuts off right away. Almost like you'd be hearing if you were hearing time on direct, or the input! I love it

Thanks soooooooooooooo much for the help everyone!

EMS is fully switched over Fire in June. Its a simucasted repeated system. No trunking CPD just narrowbanded all the Zones so they arent going anywhere for now. Thats the way P25 sounds no repeater hang.

Honestly I like the old analog system better. I monitor them on a motorola XTS5000

Here's a post I made to the CARMA list a few days ago...

CFD testing on their UHF system this morning.

Channel 1-477.7875 ($ 293) Main
Channel 6-476.6875 ($ 293) Citywide Fire
Channel 11-460.6250 (156.7) METRO 4
Channel 12-477.9875 ($ 293) Joint Ops

Sorry, I don't have the other channel numbers/names/frequencies. This was all I could catch over the air before I went to wok. They still have access to the analog UHF channels. I heard them on 462.975 today.

I've been keeping regular updates in this thread. "Channel numbers" aren't always going to be accurate as thier are approximately 28 "zones" in our radios and each "zone" is set up differently. Common channel number is 4 ("New UHF Simplex Fireground) in both EMS and Fire Zone. I'm also trying to keep the database updated..

I know you weren't "cruising for compliments" but thanks for this effort, Dave!

No , not at all. I just figure its easier to keep it all under one thread.
