Frequency changes in the Douglas County MPT1327 system

[DCMon]

I have submitted some changes to the frequency plan of the DC MPT-1327 system today. Four sites have one or more frequency changes. Info should be up as soon as my update comes up for posting.

DCMON is there any new updates on vhf system new freq ect? and is DFPA 151.160 on the county vhf system now?

thanks

DCMon, thanks for the updates. I've posted them as of now. Please let me know if there are any incorrect entries.

Also, next time, can you list the frequencies one per line, like this:
01 453.33550
02 457.21750
03 452.16750

(yeah, I know the frequencies are bogus, just an example).
In this format I can just cut and paste instead of having to switch between windows

Thanks.

Dc Mpt-1327

When was this system suppose to come online? I was told by another source that the MPT system was going to be used by public works and other admin people. Nothing about Police/Fire. Im a volunteer firefighter with Glide FD and they havent mentioned anything about switching.

Your right FD and PD are staying on Vhf. They just adding freqs to the MPT system for pW and others useing it.

Yes the DFPA is on parts of the county system now. Nothing new going on in the vhf channels.

There are no alternate or secondary data channels on this system. The frequencies that are colored blue should be black.

According to Ray Duncan County 911 Director, the MPT1327 system is to slow for emergency communications. They ran some tests and they feel it takes to long to enter who you want to call and etc to be safe for field units. Seems like something that would have been check on before hand. Also, they cannot sell space on the MPT system because it is an emergency system and the FCC will not allow it. Even Douglas Electric which uses the system had to apply for and receive special permission from the FCC and they are considered an emergency service. So much for the system making money for the county.
While were picking the updates apart, I also heard the new digital paging system isn't working out and may not be used as the only paging system for the county. Must have been some salesman that sold them all this high priced stuff.

gotcha, that'll be fixed here in a few minutes.

Thanks for posting the updates!

With all the geography there UHF trunking just doesn't make much sense. Wonder why they ever went that route...

A uhf trunking system would work in Douglas county if it was Motorola Type 2 and if they planned the system out and added more sites them what they have. But i think if they put in place a Vhf Motorola Type 2 system up they would have like it a lot better. Sounds like Douglas county throw away a lot of money on a bad system, MPT1327 system never work. They should of talked with Yamhill county before they got theres.

thanks DCMon for the updates.

Here in Glide were using both pagers, the little digital ones and the Minitor II & IV. Some of the longer standing members got the Digital Swiss Phone pagers. Fire dispatch tones both out, voice and digital. Talking to some people at the FD everyone in the county hates the digital pagers. Looks like another failure for the county like the MPT-1327 system. The VHF system in my opinion is probably one of the best ones I've seen. If its not broke, dont fix it.

MPT systems arn't really meant for Public Safety operations due to the low (in todays standards) 1200 data rate the system has a slower access speed than say Motorola Type 2 at 3600 and 9600.

Typical call setup times are around 0.4 of a second for single site whilst a large muti site call setup can take up to 1.5 seconds.

These MPT systems can and do work well and are alot cheaper to build out than Motorola and of course being an open standard it offers more choice of user equipment, but are better suited to non-time critical users.

Money wasted here like usual

I think the main problem we have here is that the county was "taken" for an expensive ride. They were told it would be the system everyone would want and so many private users will want on it you make huge sums of money.
You are right it does work ok in strong signal areas and if you have the time to dial up who you want to speak with if you hopefully have the right number. This system here is so bad the main user, Public Works is using cb radios for contact once units are close enough to reach each other on work sites. Whats up with that!! 100 million dollars and climbing for 10-4 good buddy on a fifty buck radio.
This is what happens when you give the wrong people control to decide and spend. All the way from dumb Commissioner Kittelman down to the guy that forgot to wire two sites for electricity - DUH!!

Interesting document on both the VHF and UHF trunked systems:

Also allot of the problems with radio systems arn't with the technology, they are often found in user training, system setup & fine tuning. There alot of companies out there that sell a system , switch it on and then leave without fine tuning it to the customers needs or providing training on how to use it.

We've got 22 site VHF MPT Systems here that run smoothly and sound great, I put it mostly down to a good understanding of the technology and willingness to spend time getting it right in the first time.

Thanks citylink uk for the info about Douglas county. Looks like the more updating to come in Douglas county. Lane county in the works to put in a Uhf P25 trunking system county wide. It sounds likes like it be good system but over on the coast and east of county they may have trouble..

Just heard 1005,(Looking Glass Fire) ask for radio check, little scratchy, but very readable. Said he was down South on the Rougue River. You wont get that from a UHF system.
