One thing I've noticed while roaming on band 4, is that google thinks im offline and not connected. To do a search I have to open a browser instead of using the google app. Play store is the same as well. Everything else seems to work fine though.
I have two band 41 sites near me. Waynesboro, Pa and Rouzerville, Pa. They both have 40978 as first carrier and 41176 as carrier 2. Now Rouzerville has 41324 as a 10 Mhz 3rd carrier. I will be checking on the Waynesboro site soon. It may have a 3rd carrier too. I have not seen it yet if it does. Strange how we have 10 Mhz for carrier 3.
My logs for shentel (Harrisburg) show 5 carriers live on different sites(3 carriers on most then 2 carriers on 2 of them).
Sites that had 39874/40072 the GCIs were 0FFFF932/0FFFF93A and 0FFFFC32. Both were by I-83 between 13th and 19th if anyone is looking. Not sure the reason for these 0FFFFXxx sites might be worth looking into.
