You'll find 11H in the Utah State Agency Radio Call Identifiers now. You will also notice that I have changed the format for that particular table because I have had to make edits to it on four occasions and to add a call sign requires typing the whole thing from start to finish. Anyone who has worked with Wiki markup language will see immediately that the changes I have made will make it much easier to do edits in the future. It may not be as "pretty" as it was before, but it is functional.
I'm sure you are probably right about this being Tribal Police, but that brings up an interesting question because all other Tribal Police Departments in the state carry a Federal Call Sign (i.e. 7B - Ft. Duchesne Indian Police, 8B - Mexican Hat Indian Police, 15B - Goshute Tribe Indian Police).
Are we sure this is an Indian Police Force? Please correct me if I'm wrong, but doesn't the Goshute Tribe inhabit the area around Ibapah? Funny they wouldn't use 15B as a call sign if that is the case...or is this like a town marshal?
