Where are you seeing those? A look at the Official Feeds page doesn't show any CFD feeds, just CPD.
Strangely, they kept disappearing and re-appearing on the desktop site. They were visible on the Scanner Radio Pro app and of now it looks like they completely disappeared from both.
I don't know anything about Broadcastify and what they have set up. It could be "possible" that the OEMC has the same arrangement as far as providing an official delayed feed? Since the frequencies that are going to be in use are not known yet, not sure how that's possible?
I streamed and listened to them last night, and heard audio from the 800 MHz P25 system. It didn't have an extra delay like the CPD streams.
I think the Broadcastify feed is independent of CFD and OEMC.
They had the same red and white star as the CPD streams indicating that it's an Official Agency Feed.

I thought this was about the upcoming change to the 460 Mhz. P25 Conventional system since it was on this thread?

I didn't know what freqs/system were being streamed which is why I gave them a listen and stated that it "may not" have anything to do with it at all. My assumption (and fear) was they were going the same way as CPD (ENC, but with delayed streams). But since they're gone now, I'll just sit back and wait for your/other's updates on their new freqs. I'm DONE with this, let's move on, and I apologize for even bringing it up here.

I was confused and since Broadcastfy had the CPD P25 Conventional information up prior to it going live, that's why I responded the way I did. I thought you were on to something since I didn't have any frequency information on the new system. The stream was the CFD 800 system...got it now.

Was it ever determined what or where the interference was coming from that was causing the issues with the T-Band frequencies? It seems that it became more of an issue in the last few years. They have been UHF T-Band P25 since when 2013?

There was an article I was sent on how the FCC was allowing radio stations to utilize part of the spectrum they were using for the input frequencies that started around the same time the interference started. New York had issues is what is was about. If I can dig it up I'll link it.

No cause of it yet as far as I'm aware. I'd rather have them stay on the 800 System then go back to Conventional.

No time frame update as of yet. Obviously September has come and gone so that didn't happen. I'm still monitoring during the daytime hours for any testing on all the licensed 460 Mhz. and added the two 462 Mhz. frequencies (462.950/462.975) in P25 Conventional/OFT. Companies are still going to firehouses for "radio upgrades", which would lead me to believe it was going to be awhile.

Until the information is verified, then we know if the document is legitimate. No testing on any of the 460/462 Mhz Chicago licensed frequencies as of today (going back on topic😁).

There has been testing and multiple keyups on several of the above listed frequencies. Mostly on the Fire Main and some on Citywide fire simulcast.

CPD Officer wake/funeral precession and detail. Old citywide fire frequently in use during events. 460.600 analog has had a persistent "clicking" on and off for some time. Nothing new here, 800 still in use.

Before anyone gets excited, during the CFD 0900 morning radio check, they checked the "old/back-up" Citywide Fire channel (476.6875) which is showing as "Simulcast Citywide Fire" on the list. This channel is still in the Zone FD800 code plug. CFD is still on 800...
