What is the status of the Pima 800 project. Last word was they were going to YRCS. I see they are still conventional.

Pima County

here is the latest from the City of Tucson,September 2012 was the last quarterly
report for 2012,the City of Tucson,requested and was granted a time extension on
construction from September 30,2012 until December of 2013.The last site still
under construction is the Swan site,the other 4 sites are TFD fire station
12,TFD fire station 17,PSTA,TOPSC,all under under call sign WPQA524.The City of
Tucson will begin systemwide testing on thier portion of PCWIN any day now as of
April of 2013,and following testing and completion of other PCWIN
sites,operations will begain on 1 August,2013.By December 17 2013, Tucson must
be integrated into the PCWIN system and commence operations.here are some more
interesting dates for other sites that are under construction right
now,Bigelow,beacon,Confidence,Arivaca,from 4/3/13 to 4/9/13,also the City of
Tucson plans to do Acceptance testing next month from 5/20/13 to 9/19/13 of
thier portion of PCWIN.Now this system is a Project 25 Phase 2 TDMA it empoloys
TDMA multiplexing technolgy,which fits more talk paths into the same number of
radio channels.This system will will be comprised of 27 sites consisting of a
Master site (control point),two identical overlapping eight-site,12 channel
simulcast cells operating in the City of Tucson,a four-site simulcast cell
(North County) operating primarily in the region of the towns of Marana and Oro
Valley North of Tucson.There are seven P25 trunked repeater sites which are
individual radio transmitter sites (non-simulcast)providing radio coverage over
wider area of Pima County..... Simulcast cell A and Simulcast Cell B are
composed of eight sites.....The third simulcast cell is the North County
Simulcast cell(Beacon,Library,OVPD, and Walker).The seven individual trunked
sites are Arivaca Govnet,Childs,Confidence,Haystack,Keystone,Mt.Bigelow and
Golder.

If it's Phase II TDMA, you're going to need to find a GRE PSR-800 scanner. It's the only current scanner that decodes Phase II. Good luck finding one, at a decent price, what with GRE currently being out of business.

Not ready for prime time, yet.

System is still on build out. Tower sites being wrapped up now. System testing is still months away. On air transition is tentatively end of 2013. FCC gave City of Tucson no more extensions as they have dragged there feet long enough. Pima County hopes there air testing by August.

By the time this system does see the light of day Uniden's new batch of scanners should be available. Or you can hunt down a GRE 800 and grossly overpay just to have a TDMA II unit now with nothing to listen to for a while. YMMV.

Actually, it is further along than you suggest. This is according to the official documents that they've filed with the FCC. Some type of system testing is to begin this month. Not really sure to what level, but like Tyrone, I'll be ready to catch it when it comes on line.

It's also according to the folks I talk to on the street.

According to the documents filed with the FCC, specifically, the timeline, radios are also being installed in vehicles. Again, don't know how many, but really doesn't matter as long as it is used

As you pointed out, the City of Tucson has to get a move on and they should be testing Simulcast A and B, before Pima County is ready.

I for one don't wish to wait for another scanner radio to come out, when one already exists. I just purchased my second PSR-800 and will be ready from the beginning. There are a few more local Tucson area scannerists that will be doing the same.

I've listened to some of the other systems come on line and I happen to enjoy listening to what has to be done to make the system ready over the air. It's nice to have the background on the system, not absolutely necessary, but nice.

Naah. That's what DSD is for.

I make regular trips to Tucson and will be happy to do some testing using my RTL _SDR dongle/SDSharp/DSD setup once this system is up and running. It currently decodes the RWC almost as good as my BC796D (which ain't sayin' much but what the hell, it was less than $20 outta my pocket for the whole setup!) Next on my list of new toys is an i5 powered desktop machine to really make use of SDRSharp and DSD. I'll hopefully have that in the next month or two. It probably won't work as well as the 800 would, but it also won't cost me $700+ either.

And you're going to be tied down to that computer as well, so no mobile monitoring, unless you install a laptop in your vehicle. An 800 would be so much easier. But, that's life, right?

Monopole's are arising

They just erected a monopole near my house at the TFD station 12, 250 S. Harrison just about a block south of Broadway.

Talked to the supervisor and he said that they are behind schedule but have time. Said that they will be finishing the erection and topping it off in about a week. Then contractors need to pull the heliax and then the antenna installation crew does it's thing. Said it's coming along. The new mompole is higher than the exisiting one currently in service at this site.

At station 12 they have now moved all the antenna's (TFD uhf and TPD vhf and microwave link) from the old monopole to the new monopole.

Well, I look at it this way:

What I do have is a laptop. And I have a RTL-SDR. And DSD installed and ready to go. What I don't have is $700 for a PSR-800

So.... yeah. That's life.
