troop h

i didnt have to do anything to my scanner but enter in the new lower freqs and it works fine i'm recieving them better too..

They are rebanded systems and, at least with the Unidens, have to be entered as such. Simply entering the frequencies will not necessarily work. You will miss 25% of the Troop H site traffic if you do not use the correct band plan.
The CSP schedule for rebanding is not something that I am privy to. When G & I stop working for you, then it is likely it is done. A search on rebanding on this site will give you more than enough information on how to reprogram your scanners.

CSP Re-banded B,D,H

at least with the Unidens, have to be entered as such. Simply entering the frequencies will not necessarily work. You will miss 25% of the Troop H site traffic if you do not use the correct band plan.

This is really interesting, since after trying to mess around with "band plans" and "custom rebanding" in programming, I scrapped the idea and simply entered the new rebanded frequencies for the 3 re-banded systems. Works great - on both a 396XT and 996XT.

I confirmed that I am receiving traffic on all (5) of the frequencies using Unitrunker AND by changing the option in the scanner to display channel data (Mode 1).

Troop D is too far away, but works on the handheld from the road.

At first, I simply put in both sets of frequencies, for example 853.6125 and 868.6125 - then I simply deleted the upper frequencies after re-banding.

Sites are ALL set up as 800 Standard Type II.

I am in Middletown near the complex.

Firmware is 1.04.00

Don't ask me how or why it works - but it does. Maybe I'm "special".
I'm glad I went "Uniden".

I use Freescan, ID Tracker and Unitrunker with a Discone about 45 feet up.

On another note, I'm not sure why sites are listed as C727 in the RR listing, when they all show 4B16.

Happy Scanning.

Update to my last post

From:

Software Support for Uniden Rebanding - The RadioReference Wiki

* XT version scanners already have the firmware updates to support rebanding. Non-XT scanners will need to undergo the appropriate firmware updates. Note that systems that are true P25 types would not require entry of the table values below, as they should get all the necessary information from the control channel.

And good news for Uniden XT owners...

I'll let you all know if this continues to be true.

so do we just subtract 15 mhz from what we have in the scanner now or are there actual new freqs as well? Also did/when are troop G and troop I changing and I could have swore I saw something posted awhle back where troop g has some 700 mhz channels listed but then again i may be wrong.

Yes on subtract 15mhz.

You may be getting a lot of traffic but I am very confident you are not getting all the traffic.

Motorola systems work by the control channel telling the radios to tune to channels based a predefined list.
If I program CSP Troop H as a standard system I will hear traffic. Why? Because the first 2 voice channels assigned are channel 37, 851.9375 and channel 56, 852.4125, you will not miss traffic. Those channel numbers are unchanged by rebanding. When we get to the third simultaneous user on the system, it uses channel 455. A standard Motorola system will tune to 862.3875 when it is told to go to channel 455. A rebanded Motorola system will tune to 851.4000. The fourth simultaneous user goes to channel 70, 852.7625, also unchanged by rebanding.

Why might you not notice it?
Since rebanding started, channel 37 and 56 have each received around 12,000 transmissions each. Channel 455 has had 800 transmissions. (Channel 70, only 198). So you not noticing 800 of 25000 transmissions is not surprising.

I will correct what I said earlier about missing 25% as I didn't realize the desparity could be that much. You stand to miss about 2.5% of Site 9 traffic based on these numbers. Site 4 and Site 7 have similar numbers. However, when Site 5 is done, you will hear only 5500 of 865,000 transmissions as 3 of the 4 voice channels will have the affected channel numbers (over 440)

"cg" is correct, here in ILL when my town rebanded i had to use "Band Plan1 and 2 to hear the 853mgz freqy's because the scanner is choosing the wrong "#" freqy cause of Motorola's new lineup #ing scheme....It looks like your hearing all but there are times you miss the call back....

Keep in mind that CSP is not a true P25 system. It used a 3600 baud control channel with P25 audio. Therefore you do need to enter the custom table numbers to track the system correctly.

Please refer to the twiki:

BCD396TFirmwareUpdate < UnidenMan4 < TWiki

After you setup the scanner, you should hear all of the traffic on a rebaned system.

As CG said, you will miss 25% of whats going on.

Just because the firmware has been upgraded in the new radio, it doesnt mean that its set up.

Can someone point me in the direction of a good site that will show me how to reprogram my psr500 for the csp re-banding? Something like re-banding for dummies lol.

Use the bottom table and your software.

If you use WIN500 you can just change the frequencies and then select the "800MHz Rebanded" table from the list.
From my limited testing so far, I would say Troop H is definately working better for me.
More to come....

Troop G is being rebanded today. Expect completion around 15:00hrs or so. (they do have an extra channel at G).

chris

 

[w2csx]

I'm not sure,but it looks like Troop C & K is being rebanded also today?

 

[cg]

No, it is not

chris

 

[cg]

It looks like Troop G is switched over (as near as I can tell from the north end of the state). They are using Ch 549, 853.7500 as the PCC.

Yes they did about 13:30 this afternoon. There was about 5 min. of no CC on 868.750 or 853.750, but all of a sudden the 853.750 popped up.
Heard the techs on the SW Comm talkgroup all morning tuning up the transmitters. That was the first hint of the switch.

[Dave520]

They seem to be using 853.500 as a channel also. (not a control channel)

 

[cg]

That is the 5th voice channel on Site 1. Several of the other sites will have an additional voice channel eventually. It had been iin service as 868.5000 previously.
