I know this suggestion is one that is going to require a lot of work but I think it may be helpful to many people in deciding what to buy or not buy scanner wise over the next few months to a year or so. Here it is, on the 800 trunking systems could there be a place to indicate if the system is going to require rebanding and the status of it?

Any 800MHz system is going to have to be rebanded.

If you want to keep on top of things, be sure to follow the FCC Rebanding Discussion thread in the Scanning Discussion Forum
or browse over the latest news on the home page.
There are some very vigilant members who submit the latest in scanning
related developments. You should be able to stay in-the-loop that way. :wink:

Not "Any system"... there are some that will require no changes at all.
For example... the Sarpy Co system I primarily monitor has 20 channels. 14 of them require no change, and the other 6 are in the expansion band and do not have to change if they don't wish.
The hospital I work at doesn't have to change frequencies either.
Douglas Co and their brand new umpteen million dollar APCO 25 system with some 2000+ users.... has to change everything.
Who says there's no justice in this world! :twisted:

Okay, I think this is an excellent time to point out some things.bsavery said:
Whereas the Sarpy County Public Safety System does not change frequencies, nobody in this rebanding gets away Scott-Free. They are being rebanded, although it is only for channel changes. Take for example the lowest frequency channel on the system at this point, 856.2375. That is presently channel 210, after rebanding that is channel 320. So this requires reprogramming of all radios and of course your scanner will no longer work properly unless you upgrade (if possible) or reprogram it (if possible.) BTW, Sarpy County is in the 2nd wave of rebanding which according to the FCC schedule should start in 2006, 3rd Qtr.
So, all of you out there who are considering yourself lucky that your favorite system isn't going to change are just not understanding the rebanding issue properly. All 800MHz trunking systems will be affected to some extent by this.

Yep... Don Starr pointed that out elsewhere in an excellent post explaining how Motorola trunking works. I should dig that up and send it along as page one of the wiki on trunking!
The part I was missing was the renumbering of the channels. I hadn't seen anywhere on the FCC or 800TA saying the channels would be changing.
The FCC usually doesn't change a period in the rules without a ton of notice and a zillion filings and such. After digging further followed by more digging and searching... I finally found reference to the new sections of Part 90.613.
Haven't actually found the new regs, but I did find a FAQ that stated they would be in effect after rebanding.
Oddly enough... still the only place listing the new channel/frequency assignments is Motorola's web site.
But to be honest... I did quit looking after several hours... :?
I figure what is going to happen, happens when it happens and nothing I can do will change it. In the meantime, my scanner works and I'm sure at some point, someone will have a scanner that works post-rebanding..... hopefully! :wink:

A very good tool. That's what got me confused and started my search for answers... under the listing for Sarpy Co... it stated "No reconfiguration required"
AT THE TIME.... it also didn't list anything in the old channel column and only the frequencies in the expansion band showed a new channel number (with a note saying PS can opt out of reconfiguration).
Now it's all filled in and actually makes sense!

Thanks for the link. Now looking at these two pages it seems to me the frequencies stay the same just the channel number changes. Do I understand this right? Call sign: WNKA279

I am no expert, but I think since they hold license as "YP" they are going to have to move or change license type.
The way I read this, the current "YF" licenses get the lower part of the spectrum first. Since no "YF" licenses are currently located in the present first 120 channels, as they are the ones being moved down from the 230 channels located at 866.0125 thru 868.9875, they get the new first 230 channels being carved out of the present 120 channels from 851.0125 thru 853.9875 and generally are just moving down 15MHz. Everybody currently located in the present first 120 channels (851.0125 thru 853.9875) are going to have to move, including Manatee County.

Rebanding will not affect your scanners as far as EDACS is concerned, other than you are going to have to enter the new frequencies in the proper LCN position. The rebanding issue, in regard to scanners, is what is going to happen to the Motorola systems (or APCO-25) since they use channels numbers assigned internally in the radio as opposed to the ones that you put in yourself.
On either CC (EDACS or Moto) the scanner receives an instruction to go to a channel number for a voice conversation. In EDACS, you the user, are responsible for having the proper frequency in the proper channel number. With Motorola, the radio already knows what frequency goes with what channel, except of course with the rebanding, all the channel numbers are changing.
