Don Root, from the California Governor's Office of Emergency Services is interested in any details available about the reported "failure"
of the PDX trunking system last evening. He's not on nwscan, and asked me to follow it up. Anyone have info/anecdotes to report? Has PPB or the media put out anything yet? Was it a "disaster," inconvenience, or just a bump-in-the-road for the IMPORTANT folks...the street officers?
Speculation on my part follows:
This was first noticed by me using a MTS2000 - I could hear carrier but no voice. I turned on my 245 and could hear the control channel buzzsaw -- indicating that the trunking controller was still working.
Scanning the 20 frequencies in conventional mode, I observed the same behavior; but on scanning the other "zones" of the SmartZone system I could still hear conversations. I suspect, and this is only speculation, that what happened was a failure in the Line of Sight Microwave receivers at the simulcast towers.
Note that MDT traffic was still working properly, as was the trunking controller during this failure. Conventional frequencies and SIMPLEX were working just fine as well.
When the failure finally cleared itself (or got repaired), the simulcast towers went into the Site Trunking mode -- meaning that the other zones of the smartzone system were not "in sync" with the primary (simulcast) zone. At that point, mobile and portable units could hear each other, but units at base stations & consoles could not... but slowly (very slowly... a talkgroup at a time almost) the consoles and base stations came back bringing the failure to a close just about 50 minutes after it started.
So, like I say, it was probably a problem with the microwave equipment or the master system controller.

Now, I wonder if this will make the city of Portland think twice about the 800 system, that they have, with that nearly 1 hour failure that occured, lastnight??
I have heard that the City of New York has gone back to a conventional system and have ditched the 800MHz System there. Since no one was able to get out on the radio's there. That's what I've heard. But, I do, know that City Brass wasn't to happy with the Morotola 800 trunkin'!
PDX's, system has been broke before, now, it might come to light that maybe this radio system is not what they think it is??

Looks like it was a total failure of the voice side of things. From what I've seen and heard, looks like they had intermittant problems from about 11:30pm and the complete failure occurred at approx. 12:20am thru about 12:35-40am. MDT's and computers appear to have been up so that is the good news. Now BOEC can try and say there was no failure but Intelligence sources confirm that they had a complete failure of voice. From what Rick says, sounds like they may have gone to "failsoft" in Gresham.
Maybe they did a reboot of the system because no other problems occurred after that.

Anybody hear any traffic this evening about the full voice-failure on the PDX TRS tonight? About 2350 or so the voice repeaters were giving carrier only (on the simulcast sites) but no voice traffic on them.
This affected Tri-Met, Portland Police, Fire Bureau, etc.
Just wondering if anybody heard anything about it once the problem (whatever it was) was corrected (about 0031 or so).
Radios went into "site trunking" about 0035 -- which means that not all of the repeater groups were talking to the main controller.
