Tait Radio to install Stanislaus County Project 25 system
Tait Radio Communications was chosen by Stanislaus County, Calif., to upgrade communications among the region's public-safety agencies. Tait's network solution will enhance the county's existing interoperability channel, expand radio coverage through difficult terrain, and replace aging equipment. The upgrade to Tait's system will also secure the primary radio tower and support the operational area's joint efforts to respond to all hazards as well as daily operations.
Implementation of the Project 25 (P25) digital network is scheduled to take place in phases, allowing for future improvements as needs arise. Stanislaus County is located in the Central Valley of California and includes the city of Modesto.

Excellent, it's nice to see a different vendor used (and another manufacturer control channel to analyze).

If it is trunked, P25 is P25!
But P25 may not always be trunked.
Anyone try to find the bid specs?
EDIT:
Look at what a Google turned up!
--------------------
Tait Radio Communications' suite of P25 products will be implemented throughout the area, with all solutions being fully P25 compliant and digital, analog and mixed mode capable with the ability to interface with radio consoles and remotes.-
-------------------------
Mixed mode is obviously conventional.

MPT-1327 is not P25.
It does not carry P25 voice channels.
It looks like "Taitnet" is conventional.
As I pointed out before, if it is P25/Analog mixed mode, it HAS to be conventional.

Is that a Tait specific limitation, because it's not a limitation on Motorola trunk systems.

It is a specific limitation of P25 trunking systems.
Older Motorola systems use their Smartnet/Smartzone control channel (3600 bps) and can support both analog and P25 digital, as well as Old Astro and old DVP/DES.
P25 trunked systems, using the P25 control channel can not support analog operation.
They only support P25 in clear or secure.

Scratch that idea. I guess the switch to trunking isn't happening yet.
My remark was based on the use of specific manufacturer OSPs that are outside of the regular APCO-25 protocol. We know a good amount about Motorola's so having Tait in the picture should add some new stuff.
Here's a PDF from the County.

MPT1327....
If they go to that they will be not liking it after a very short while. One of the agencies up in Oregon (Yamhill County) has a MPT trunked system and it has been plagued with issues ever since start up.
In fact, the law enforcement side are still using the radios, but as conventional only due to officer safety concerns and issues with the system.
In fact, 2 different consultations were done on the radio system and both consulting firms recommended getting rid of the current system and replacing it with a system that has more interoperability capability than the MPT system does.

Since it will be P25, it will not be MPT1327.

Sorry, just correcting incorrect information so to prevent others from getting confused. (and without too much sarcasm, if I do say so myself!)

I understand. I'm just trying to be preemptive. I'd rather not see us go off on an MPT tangent. |

Just to clarify, TaitNet is a name used by Tait to describe a system solution (ie. Infrastructure, Repeaters, Radios...) using their products. This can be Conventional Analogue, P25, MPT.
P25 cannot be used over an MPT network. MPT systems do work well but in my experience not really intended for Public Safety use and has to be set up properly with fine tuning to work well.
As said before, I would imagine in this case the system to be P25 Conventional.

Stanislaus County
I have located the original source document for the proposed upgrade
http://www.co.stanislaus.ca.us/bos/a...060725/B07.pdf.
Essentially Stage 1 has already happened at a cost of $180,000 and includes existing TB9100 Tait P25 repeaters. I couldn't find the original stage 1 upgrade document. Stages 2 and 3 are contained in the document above.
Other relevant documents:

PS Although I am on the other side of the world I am personally familar with Modesto, having spent a week there back in February 1986 while being billeted for a church conference at First Baptist Church Modesto.
