Keep the 800 system a keystroke or two away, as they'll be back on it before too long. Same weather conditions that caused these issues are expected again, in the coming days.

As predicted they had Fire on FD800 from early this morning until 1000 Hrs. EMS remained on the UHF Conventional from the time I started monitoring this morning. Hopefully no one gets hurt if during one of these "atmospheric anomaly's", someone needs help or assistance in an emergent situation. The OEMC dispatchers only clue something is up is when someone reports "did you hear me on the portable" and the obvious answer is no. While it's not unusual for a portable radio to be out of range at times, this would not cause any notice until more than one company reports problems or a Battalion Chief is attempting to give a progress report from in front of a building. This is the danger in this tug-of-war of whomever is making these decisions. I know quite a few on both EMS & Fire and this is becoming a bigger concern on the street as more of these issues occur. The portable vs apparatus radio programming is one of the possible hold ups is what's being told out there , and while I understand the inconvenience (and also had to work on portables when they switched from analog to P25 Conventional in the past), I'm sure if it's working, they'd rather stick with that. As I posted, some apparatus radios have been programmed previously, and as time progressed last week, a little searching on the radio found the proper zone.

Boy I understand the serious nature of the situation. I do have a question(s). Have there been any issues with the simplex fireground channels? And are most of the current issues related to the repeater systems?

Just the repeater UHF-T frequencies are affected that I'm aware of.

Fire-Englewood and EMS-Englewood are currently utilizing the FD800 & EMS800 Zones due to the same issues previously mentioned. So far...Main-Fire and Main-EMS are still on the Conventional UHF system.

They use the same fireground and other uhf tac channels when on either uhf conventional and the trunking channels.

Hearing the radio shops on the Englewood talk groups
Yes..a couple fire companies were reporting their radios were "beeping", but no issues reported by any other companies, EMS Englewood, or Airport talkgroups who all use the same site🤔

The OEMC tested with quite a few Fire and EMS companies and from what I heard, no issues on the FD800 or EMS800 Zone. I'm wondering if the "beeping" was actually the low battery warning, and since the APX8000's are new to them, maybe emits a different tone than they're used to?

Anyway, they switched back to the UHF P25 conventional, and I'm already hearing problems with some of the portables on both Main and Englewood. Wouldn't be surprised if they're back on the 800 trunking system before the sun rises.

As some of you might have been following along today, the day started out with Fire-Main and Fire Englewood utilizing the FD800, till around 1500 Hrs. and Fire-Main switched back to the P25 UHF Conventional channels, but Fire-Englewood remained on the FD800.

In the past 15 minutes or so, EMS-Englewood is now on EMS800, Fire-Englewood remains on FD800.

Starting to hear complaints on the Main Fire and Main-EMS on the P25 Conventional system, starting to have problems again. Last night at this time, I started hearing the same thing, and by the morning, they were on FD800.

Last week, companies were reporting to different locations for "radio reprogramming". I've had people tell me they have no intention of switching all operations to the 800 too. So, as happened when we went from VHF analog to P25 Conventional, some people swore up and down we weren't going to digital because of 9-11 in New York's radio issues. We will see I'm sure.

I gotta ask for some help on this...it's driving me nuts!! I have a Radio shack pro-197...I programmed this new system in several weeks ago and was able to listen to CFD on 800 no problem...HOWEVER...this most recent switchover to 800 all of a sudden the radio would not pick up any traffic..I know this because I have a different radio that was working...I'm wondering if something was changed on the 800 system that made my original programming invalid? I downloaded the system from Radio Reference so I can't imagine it's a transcription error...The one item I'm not sure how to classify in my software is site type...the download shows MOT p25 standard in the scanner software..I tried some of the other choices like Motorola 800 Type II but that didn't seem to work either....Another question.... should an older Uniden Trunktracker IV be able to work on this new system? Seems to me it should as it works on the current uhf system..Any insight would be appreciated.
