Enos,
Which way did you end up driving?
I think site #34 is Barton Peak, which is the closest site to Manti, so that would make sense that you picked it up. A couple weeks ago I drove from Gunnison to Manti and then Nephi. I rode in the back seat with Unitrunker running. I have some good screen shots from Gunnison, Barton, and Levan. At that time Barton and Levan had been rebanded but Gunnison had not. My internet at home has been down and I keep forgetting to bring the screen shots to work so I can post them, but I will remember one of these days. I saw a little bit of traffic on Levan and Gunnison, and none at all on Barton. Barton is the only signal I can Rx while inside Manti, same as you. South of Sterling I start to get Gunnison, and start to lose Barton. Maybe next time you go you could drive south and see if you get the same results.
I double checked the FCC records today and indeed 856.4375 is licensed to Barton and not to Gunnison. If you find anything to the contrary please say so. Lets both double check the next time we go there. Hopefully someone will start to talk on that site soon.
