If you are in the area, and have a scanner, try listening in on the following frequencies:
Subcategory: Tulsa County Fairgrounds/Tulsa County Fairgrouds/ Expo Square Details (Entertainment)
www.radioreference.com
453.9000 WRAB304 127.3 PL Fairgrounds 1 -- Primary Tulsa County Fairgrouds/ Expo Square
453.4000 WRAB304 127.3 PL Fairgrounds 2 -- Secondary Tulsa County Fairgrouds/ Expo Square
454.4125 127.3 PL Fairgrounds 3 Tulsa County Fairgrouds/ Expo Square
They have received a new license for a trunked system (
ULS License - Industrial/Business Pool, Trunked License - WSEN283 - Bearcom Operating) (and I don't see them setup on the statewide Trunked system OKWIN) , but I don't know if that is up and operational for this event yet, and even if it is, they will probably have the feed going to one of those older frequencies. I'm betting that they are still using the ones above.
Trunked system:
Mobile radios:
451.5125
451.6875
451.7375
452.0125
Portable radios:
456.5125
456.6875
456.7375
457.0125
If you have a scanner, you could be listening in to the channels this week to see which ones are live and which aren't as well as getting a feel for what "chatter" is flowing over them.
I don't know about taking a scanner in to the fair, as that may set off alarms for them, but that may not be a bad idea if the fair is a large enough venue and if an issue crops up on the other end of it, it may give you a few minutes more time to get out.
Just a thought...
