Yea typically, which is why I was asking.
RID's 1840001-1840020 were seen on EMS Command Talkgroup keying up rapidly this morning. My "suspicion" is these were new radios assigned to the EMS Support & Logistics Division in preparation for the Chicago Marathon this weekend. Previously I had SLD radios with the old programming of 108xxxx Radio ID structure. Since SLD falls in the Field Division South boundaries (South of Roosevelt Road), they're assigned the 18xxxxx series. The 4 (184xxxx) would indicate it's a Specialty Apparatus, not an ambulance, which falls in line with the radio programming structure.
As of today, over 50 of the 80 assigned ambulances have the new MDT's and apparatus radios programmed to the 800 Trunking system. This doesn't include any spare ambulances, the companies are using the portables. In addition, over 30 fire apparatuses, including Battalion Chiefs, Deputy District Chiefs, Exempt rank personnel have had their apparatus radios reprogrammed.

Received this today:
"FD800/EMS800 RIG RADIO AND MDTs -
The CFD has been upgrading rig MDTs and reprogramming rig radios to include the ability to scan all
channels including FD800/EMS800. Companies will report to the Radio Shops for these upgrades.
In addition, BCs will be issued a second portable radio in the near future so that transmissions are not
missed when operating as an Incident Commander and talking on Fireground or Main/Englewood.
Truck companies started going this week. The remaining ambulances will continue until they're finished. For those documenting radio ID's, a couple errors I've made note of:
2-2-2 (RID 1402227), should be 1902227
Ambulance 40 (RID 1830407), should be 1730407.

CFD is back on the UHF-T P-25 conventional frequencies
Appears to be an issue with the Harris consoles losing connectivity. Motorola consoles are able to transmit without issue (noted by the 911xxxx Radio ID's). Heard of a similar issue this morning. Seem to be an issue at OCC as a portable is being used on CPD channel.
The announcement has been made "we're no longer on the trunking/800 system" at various times when a company is on the wrong zone. Something happened since it was initiated at 9PM last night, and don't believe this was a "planned" event. It's still my belief the Harris console link to the system is off-line as I mentioned before. Any responses on the trunking system have been on the Motorola tabs on the console because of the Radio ID's being transmitted. When I was at Midway, the Motorola tabs were not used because it disabled the recording capabilities on the 800 Trunking system, which I believe is what happened here. At this time, CFD is no longer on the trunking system.

Around 2115 Hours, all CFD switched back to the 800 due to issues with the portables again. I've been hearing companies having problems with portables and some of the southeast side companies not being able to get through at all even on apparatus radios for the past couple days. It became worse in the past couple hours.
"Attention all companies, we're switching back to the 800 Trunking system"..
"Attention all companies, we're switching back to the 800 Trunking system"..
On my end, I noticed the reception of the T-Band freqs is worse than ever. I was in Cicero on Thanksgiving and yesterday, and had a hard time receiving CFD on my SDS100 and my Icom IC-R30. On the other hand, the 800 MHz Phase II system came in crystal clear, even up here in the North Shore area.
...and they're back on P25 UHF, but for how long this time? Dangerous gamble if someone needs help, calls for it on the portable, and just happens to be a moment the portables have issues again. 
Pretty sad a large fire department's communication system performance is based on the weather.

And the game of musical radio systems continues
The same pattern is starting again on the P25 UHF system. A couple companies have portable issues, than a couple more, then it happens again ..and a few more then...get those Phase 2 Trunking scanners warmed up, might happen soon..

Anyone else noticing the portables are breaking up very badly again on CFD P25 conventional? Will they pull the trigger and go to 800, or will they wait until someone really needs help? Tick tock....tick tock..
Probably will wait until the sun crosses the northern hemisphere at just the right angle and it will clear up. Imagine a communications system that is dependent on weather conditions in the 21st Century. You don't have to, just tune in to CFD P25 conventional and wait...

They seriously can't be blaming this on sunspots or weather... Why all of a sudden after being used daily for 10 years its now a problem...Anyone else noticing the portables are breaking up very badly again on CFD P25 conventional?

It's as a result of interference from a radio station due to the conditions. It was pretty bad this morning when a Metra train hit a car it became very evident. On another incident unrelated, a Battalion Chief ended up calling them on the phone to get his message to them. A few days ago, the OEMC couldn't hear companies transmitting at all on both portables and apparatus radios for a period of time. It really is dangerous because of how it happens.
What radio station is in the UHF T-band that is causing it? Or is it stratospheric ducting from another T-band agency
I was told a radio station. don't know which one.
Not sure how a Radio station in the 87-180 Mhz would cause interference on 476-490 mhz and why is it intermittent.. just odd all the way around. They just need to do the switch to the 800 system and be done..
