I got the template from KDOT through a Kansas Open Records Request. If it has been a while, you can request it through their website and share with the rest of us any changes or additions you find.
When I got the first one from them it was by email in a PDF format document. I took them over a month to respond to my request (
I understand it caused quite a stir among the various agencies and they were trying to figure out how to legally deny the request) I then pulled the info into an Excel spreadsheet to manipulate it. That first one they released had some talk groups that didn't really need to be made public and I redacted those. Oddly enough, the ones they did redact themselves were talk groups used by the Radio Techs.... I guess the "geek squad" thought that if they didn't tell us about them, we wouldn't find and identify them ourselves....
