OKWIN Rebanding Status

[K5TXC]

I'm in Oklahoma City today trying to listen to the OKWIN system. I keep getting a random talk group pop up with a frequency of 852.750, which seems to be a control channel of some kind. I have tried putting in the control channels listed in the DB, and frequencies suggested in the discussions. Anyone else having this problem?
My radio is a PRO 106 using Win 500 to program.

I probably could have been looking over your shoulder while you were doing this, as I had the same issue with mine. Thanks to Butel for updating the SW on all the covered models.

Doesn't OK have an 800 MHz nationwide channel(s) they operate on from time to time? I have an 800 MHz that we use with my local fire/police dept and the last bank is mutal aid nationwide, rebaned and non-reband...Can anyone advise if OK is part of this? I will be there in 10 days or so...

Thanks and be safe

My best guess is that we most likely have a frequency for national emergencies, probably military
or national guard affiliated. Regionally speaking, we have regional mutual aid frequencies RMA
used often.

However, I am not specifically aware of a national 800 frequency.


I am sure some of our "scholars" here could provide you with a more cogent answer.

The state/Tulsa TRS supports the I-Call/I-TAC channels for pre-reband and 8Call/8TAC for rebanded. As you note, these are national mutual aid channels for 800 MHz systems. I can't ever recall hearing them being used. You are more likely to hear the mutual aid talkgroups, both state and regional. They are listed in the database as such. These received heavy use during the wildfires this year.

I've been receiving the Muscogee traffic once I clear Henryetta going east on I-40. I downloaded the file from RR for the three-county OKWIN system, not the 31 county OKWIN system. I use ARC500 and differentiate the two trunking systems... one I call OKC DPS (31 county system), the other (3 county system) I call OKWIN. So all of the talkgroups I enter as a scannable object for the OKWIN Muscogee system, which includes Muscogee OHP, and local police, fire, and sheriff I hear clearly because they use the OKWIN Trunking system information I downloaded. You'll need to enter the Control Channel frequencies specific to the APCO-25 sites.

If I enter these new frequencies into my RS Pro-106 scanner, it should not miss anymore traffic? ....by the way, I'm up-to-date on my firmware.

So, reading this, it appears that some OKWIN sites will work post-rebanding as long as they don't use "splinter" channels in the 851-854 spectrum (splinters are the ones that have a 0 in the 4th place after the decimal).

If the DB is correct, then the following sites will still work on old scanners since they have no channels listed greater than 861 MHz:

1, 2, 3, 5, 9, 10, 11, 13, 16, 17, 18, 19, 20, 29, 30, 34, 35, 36, 37, 38

Yes, that's Tulsa there. And remember, I said "If the DB is correct". That's called a caveat.

It seems to me that since there are 36 control channels and the Pro-106 will only handle 32 at a time, if I weed out channels like Owasso that are pretty close to Tulsa and 859.9375 and one other that would have a pretty good chance of not being used, I can fit the whole system into one TSYS. Sound savvy?

[HogDriver]

And, oh, by the way, since many of the control channels are outside of the 851-854 range, will they not eventually change or do they not count?

??? I only see four control channels listed for OKWIN Site 1 (Tulsa).

Tulsa Site Details (Oklahoma Wireless Interoperability Network (OKWIN) Motorola)

A little odd that they are all marked as "primary", but only four by my count.

I am totally lost on this analysis, but it is early in the morning.

Using site 20 as an example. The current frequencies are: 856.48750, 857.48750, 858.48750, 859.48750, and 860.48750. Since the frequencies are above 854 MHz, this site has not yet been rebanded. Without knowing the eventual rebanded frequencies, how have you determined that the site will still be trackable with older scanners after rebanding?

[nd5y]

Some of you guys do not understand what rebanding is.

As far as OKWIN is concerned, rebanding means relocating the NPSPAC band from 866-869 MHz to 851-854 MHz.

Some of the OKWIN sites never had frequencies in that range and are not subject to rebanding.

Adding new frequencies in the 851-854 band to a site that currently only has frequencies in the 856-861 band is not rebanding.

Frequencies in the 856-861 MHz range are not subject to rebanding. If any of them change it is because of system expansion or other reasons not related to Sprint/NEXTEL rebanding.

[HogDriver]

So am I going to have to figure out which towers are not Rebanded and put them in a separate TSYS? One for Rebanded with a rebanded trunking table and one not Rebanded with a "normal" trunking table?

And then have to duplicate talk groups in both systems???

Sounds kind of jacked up!

In that case, I don't see them being rebanded at all because no channel is above 866 MHz.

As you said, it's early. :-)

Oh, it's jacked up alright.

But it's a little less jacked up if 1) your local OKWIN site never had channels above 866 MHz meaning it won't be rebanded or 2) it was rebanded but the new channels below 854 MHz are not "splinters" (meaning each one has a 5 in the fourth decimal place and not a 0).

I'm into listening - not big on radio for radio's sake. The truth is, as I admitted in one of the other rebanding threads, I don't understand rebanding. The whole truth is, I really don't care. I bet I'm like a lot of people on here that have two and only two interests in rebanding.

1) My scanner stopped receiving my trunking site(s).

2) What, if anything, do I have to do to make it (them) go again.

My site 8 works. The only other sites I encounter regularly are, Norman, Lexington, Arbuckle, Ardmore, and Marietta. I'm only wondering what I have to do in order to keep these sites trackable.

I'm sorta like you, in that I'd rather know where the apparatus is responding than know what talkgroup they're on, but I do admit to geeking out on the radio part.

The OKC site (8) uses splinters so you had to enter the custom table stuff in your Uniden to make it work.

Norman (40) will be rebanded at some point. If they use "splinter" channels below 854 MHz, then scanner users will need to jump through hoops to track properly assuming they have a radio that is capable of hoop-jumping.

Lexington (7) has been rebanded (per the DB) and uses splinters, so a rebanding-capable scanner will need to be adjusted accordingly. Older trunking scanners (i.e., my BC780XLT) cannot.

Arbuckle Mtn (20) appears to never have had NPSPAC channels so no change. Same for Ardmore (38) and Marietta (36).

[HogDriver]

So again I ask, do I have to have 2 separate systems loaded with duplicate talk groups? If I drive down to camp out at Lake Murray, will I pick up Ardmore on a rebanded table or is Ardmore using a normal table?

[nd5y]

The only scanner I have used on rebanded systems is the BCD396T. It only requires adding two custom band plan tables. As far as I know most other scanners are the same.

I would suggest that you read the wiki article for your particular model of scanner to determine what exactly you have to do to program a rebanded system.

You do not need duplicate systems or talkgroups.

If you add the rebanded tables and then go to an area with non-rebanded 866-869 or 854-561 MHz channels, it will still work.
