Changes to the Code Plug and APXS000 HXE Portable Radio CODE PLUG CHANGES:

UMETRO 3 & 4 removed.

City Wide Fire frequency changing
470 to 460.

Removed the Direct Zone.

Removed PDD zone (CPD non-encrypted channels)

Old dispatch channels (470) becoming Back Up channels. Three new zones were added for Back Up Channels, Back UP FD, Back UP SE, and Back UP EMS.

New dispatch channels are being developed for our dispatch channels. FD, SE, and EMS zones will be the new channels on 460 frequencies.

UMETRO 1 & 2 now in UTAC Zone.


No confirmed information on new frequencies.
Battalion Chiefs have been reporting to the radio shops to have their "radios in the box" reprogrammed to the new frequencies. The field is being told they will start using the new frequencies sometime in September. No further updates from previous posted information.

For the Chicago Marathon, CFD used the new FD Event-1 (TGID 1017) and FD Event-2 (TGID 1018). Both channels were self-identified at various times and the OEMC was communicating with the Command Post on FD Event-1 for any received 9-1-1 calls. The JHAT/Haz Mat (TGID 1011/Encrypted) also was in use as it was in previous high-profile events.

A couple of exempt ranks were testing the range of the simplex Special Event 1 (478.500), Special Event-2 (481.500) and were describing that these channels were in the Special Events Zone (New). This confirms what I've been hearing the last few weeks...the new Special Events Zone being reprogrammed will be a mix of the 800 and conventional simplex channels currently in use.

CPD was using PD Event-1 (TGID 5411) and partially encrypted. This talkgroup was also self-identified during the check-in's this morning.

The "soon to be old" Citywide Fire (476.6875/P25 Conventional) was being used by the Command Post to communicate with the cart teams, bike teams that were on the course.

This system Radi-Link (Capacity Plus Multi Site) Trunking System, Chicago, Illinois has been primarily used for many years now. Superior Ambulance was using talkgroups this year and not the Diga-Talk system. Any race activity, injuries, security issues, Aid stations etc. is here.

This system, does it host all marathon operations communications? Or just superior’s? While on site today at the marathon I noticed marathon staff using radios from comm direct, are those set up on that system, or an independent marathon specific system?

I heard many complaints from superior crews about the radios not working well. Is this system known to have issues? Could it have been the specific radio models they were using(XPR6550)?

I don't know what else I missed other than what I described. Don't know about Superior's radio issues, but heard a couple of their units dispatched for medical incidents and no one complained on the radio. Radi-Link has been leasing their radios for various city events for awhile now and haven't heard any issues being mentioned.

Companies have been reporting to various houses for "radio training" and concentrating on the "Mayday button" and a general refresher. A friend of mine who attended it described it as "nothing really new except don't press the big button on top unless you need it!". As I previously mentioned, by doing so, it transmits a "dead key" over fireground until it can be reset and if you happen to be in range, your scanner will lock up on Fireground.

Another item of interest was the 460Mhz changeover timeline. While nothing is set in stone, January 2024 it is expected to be fully grid tested, and a "soft" migration. That usually is code for EMS first, and if it works well, then Fire. The conventional channels are in the code plugs as they are now. Admin, Fireground, Ops channels, Fire Tac are retaining their channel position. As it's been noted, Fire-Citywide's frequency is changing, just not the channel position. EMS Zone will have the Fire channels on the upper channels, while the Fire Zone will have Main and Englewood Fire on the first 2 and last 2 channel positions as before.

In the other thread: Chicago Fire Department 460Mhz. P25 a contributor posted the flow sheet for radio programming. While I wished the input information would have been redacted at least, it appears that it was accurate and I'll leave it up to others to decide if they want to add it to the database.

I'm so confused why the city decided to put the TMA on the DOA TETRA system at O'Hare and not on the OEMC system like they did at Midway.
The "original plan" was to mirror the way Midway was set up. That's the reason for the two stand-alone sites at the airports and the assigned talk groups that were posted on the database. However, CDA (Chicago Department of Aviation), wants total control of O'Hare, but CPD and CFD were already committed to the city's P25 system as well as all of Midway. The ORD Radio Shops are controlled by CDA and not the OEMC. Midway used to have an OEMC radio tech on premises during business hours, but CDA put an end to that and he retired. That's why radio ID's don't follow the OEMC's programming structure on the P25 system also.

The Water Department was performing radio tests on all the known talkgroups listed in the database today with RID's in the 475xxxx and 481xxxx. I don't know if they're going to start using the system a little more often than they do now?

"800 Radio Update

The 800 radios will be a fixture in our department well into
2024. There has been a supply chain issue cited as the reason
many receiver sites are waiting to be rebuilt to utilize our new
frequency."


In summary, no changes in the near future. CFD will be remaining on the 800 trunking system for awhile.

They should stay there seems to be working for them
Agreed, but I still believe the money tree is bare when they shake it, and since they have a working radio system, it's no longer a priority like before. "Fund reallocation" perhaps?

Doesn't matter, except the 130+ house scanners they bought 10 years ago are useless since they can't monitor P25 Phase 2 talkgroups.

I had recently asked someone who is "in the know" why the persistence of CFD to move back to the UHF band for dispatching ops and the answer I was given is because the command staff can't scan (reliably) between the dispatch talk groups and the analog fire ground channel.

They have issued them two radios to use on the fireground a couple years ago. The 800 radio zones can be set up to scan multi-bands if they reprogrammed and a "box was checked". They hold up the Command Vans too soon in many instances.

I'm very familiar with the programming and capability of the radios and so is the one I was talking to, but scanning between trunked and conventional still leaves some to be desired, especially on Moto radios.

I mentioned two radios, not standing in the street, etc... and they don't want any of that. One radio that scans is what they want, which means they have to go back to UHF. At least that's what this administration says...

I'm familiar where this is coming from, but they aren't going to UHF anytime soon.

Why would they do this when they have a house full of actual Motorola radios? Just grab a spare radio for the fire house. About 20 years ago I would sit in station 58 in Los Angeles during busy nights monitoring the field action on the plug buggy radio through the vehicle PA system. Or walk around the station with a spare STX 800mhz portable

It's the CFD way, to have a scanner blaring in the background...LOL! But...that's what they're doing now, leaving a portable on in front or in the tower to listen, but not all the houses do that.

Any reason they couldn't move Fireground to an 800mhz freq? Seems much simpler...

While there are a lot of places that are using trunked talk groups for tactical/fire ground channels, theres a lot that goes into need to make sure you have good in building coverage with the system. I can only imagine all the work that would entail in just the many high rises downtown.
