Jefferson County possible Re-Banding?!?

[bob-the-scanner-man]

What in the heck is going on??? When did the 700mhz system come into effect???? I thought they were REBANDING to 15Mhz lower than where they were, now they're going to a 700Mhz system? So basically, in a few months my Pro-96 will be useless? Is only Birmingham moving to 700mhz or is the County also moving?

I guess I was in the dark as to what rebanding was. I thought they were just moving down about 15Mhz in the 800Mhz band, I didn't know they were going to a new system. Pro-96, my friend, you were fun while you lasted.

we dont know yet if the county will go over or not the question is if they are way are they rebanding, my guess is for a backup system, these freqs they are testing on are not even lic.no where, its now just a waiting game my friend, i have not yet heard anything on the 700 freqs

 

[dave911]

The frequencies I found were just from searching the 700mhz band. I have a Pro-96, so I can't trunk track the 700mhz band. If they do move there, I'm buying a new scanner.

 

[medic9351301]

dave just currious about yoour pro 96 did you do a mod or something to allow you to hear 700 cause according to the specs it does not pick up any 700mhz stuff just wondering oour unidens wont go bellow 793.000

 

[puzzleriddle]

medic thanks for the chart. odd how the fres from 792-796 are not listed? makes me think what I am hearing may be rf intermod

 

[medic9351301]

ok guys i have researched this stuff for a while and it appears to me that the channels that have been posted on here appear to be in the commerical part of the 700 mhz band see this chart

http://wireless.fcc.gov/auctions/data/bandplans/700MHzBandPlan.pdf

i found a great deal at a pawn shop on a pro 96 would have bought it but according to radio shack specs it does not work on the 700 mhz band 25-54, 108-174, 216-225, 406-512, 806-960, 1240-1300MHz range if read right dave 911 has a pro 96 or i might be wrong

my 996t only covers these bands 764.000-775.9875, 794.000-805.000
according to this chart public saftey is here

http://www.fcc.gov/pshs/docs/public-safety-spectrum/revised700ps.pdf

this is getting really complicated i have found some other docs i post later from the fcc website

 

[bob-the-scanner-man]

So does that mean that they aren't going 700Mhz? Is it possible that the 700 freqs were from something else?

 

[medic9351301]

bob i dont know if they are or not but as you can see in te chart them freqs are not in the public saftey part of 700 mhz a question that was brought up was why did jeffco reband and not concentrate on 700 band i would think that just maybe bham would go and it would be a simulcast or patch site since bham is in the high 800 range all my radios at the station are 996t and we can not afford to buy 30 new radios at 500-600 dollars a pop all i know is that a while back all the radios in he city of bham were reprogramed to support changes i dont even know if the astros rados will do 700 mhz only time will tell us i would be currious to know what radio dave 911 is picking up the channels on there is only a select few radios that will cover the whole 700 mhz band as of this time no radio shack handhelds will that leaves only uniden and gre i would recomed the uniden 396xt,

REbanding is a Requirement & NOT a choice

From the Public Safety/Private Partnership link I posted:

"The PSBL and the Upper D Block commercial licensee will form a Public Safety/Private Partnership to develop a shared, nationwide interoperable network for both commercial and public safety users."

This all fits the way I'm reading it. It explains the lack of a local agency license and it explains the use of commercial frequencies in the band by public safety agencies. Public safety has preemption capability/ priority in case of emergencies. Otherwise, that part of the band is shared:

"Providing for shared infrastructure will help achieve significant cost efficiencies while maximizing public safety’s access to interoperable broadband spectrum. "

Thanks again Eddie. does anyone have an XT scanner to program these freqs in Conventional Mde showig radio ID's so we can figure out how & who is suing them? the RS/GRE scanners do not do Id's on conventional frequencies

I have a Pro197 & GRE PSR500 BOTH cover the whole 700mhz band?? and the latest RS radios are GRE inside ONLY the name is different.
pro 197/106

i am tired of trying to figure this crap out i have my 996 searching the entire 700 band and its picking nothing up so the heck with it goes back to the old saying (IF IT AINT BROKE DONT FIX IT) i now a guy that has a 396 xt i will try to borrow it for a couple of days and see what i can get, also i understand about rebanding but if they were going to switch to 700 it seems to me they would have just concentrated on the 700 stuff.

 

[CyberGoth1440]

If you configure the pro-96 for "Extended" frequencies using Win-96 you can monitor 700Mhz, but not trunk-track it. I've always heard 700Mhz traffic when I play around with that band, I think it's a "birdie" thing
because the 96 really isn't really designed receive those frequencies. The new CC 854.6375 seems to work fine for me.

 

[CyberGoth1440]

The 700Mhz frequencies are just a "birdie" type thing peculiar to the '96 when you use the extended frequency mode - they are all exactly 61.975Mhz below the actual 800Mhz frequency.

JeffCo/Bham Rebanding

Here's a thought - just a thought, mind you. Could they be testing the 700 mhz band for propagation and reception data with the possibility of switching to the 700 mhz band at some point in the future? There may be some questions about whether the 700 mhz band will give better coverage or not. It may have something to do with upgrading the dispatch capabilities - i.e. - going to doing all the dispatching by using the computers in the cars?

 

[CyberGoth1440]

Birmingham City is still using 3 of the old KSQ471 UHF frequencies for mobile data - 460.175, 460.375 & 460.475 - note the two UHF antenna's on most of the patrol cars. As for the County, check out this link -
Jefferson County, AL Sheriff's Office - radio-ip.com

 

[bob-the-scanner-man]

So basically, we've all kind of jumped the gun on things? I mean with the "moving to 700mhz" deal? I hope so. Also note that I haven't had any problems recieving anyone Birmingham or JeffCO on 800mhz.

 

[CyberGoth1440]

If they do move to 700Mhz, I'm not buying another $500.00 scanner. Next thing will be encryption or something else that would make my "new" scanner obsolete. BTW, looking at the spec sheet for the Motorola XTS5000 HT's it looks to me like the model they use supports 800 & 700Mhz. http://www.motorola.com/staticfiles... Files/R3-4-2009F_XTS5000_new.pdf?localeId=33

Concerning my previous post: the 61.975Mhz thing seems to apply to the 854.6375Mhz CC only.

Medic... I use Win96. You can enter 700mhz frequencies with it.
