Finally got band 41 driving around KCK near I-435 and stateline. However, even though DEBUG says I am on band 41, signal check says I am band 26. Seems to be a bug with the latest version of signal check and 4.4.3. I notified blue, let's see what happens.
Used the new spark service indoors at several locations and this whole spark thing really boils down to being able to get decent (say 6-7 mbps) speeds indoors which is big c/w what we had previously. It does seem that I seem to wander to band 25 taking a few steps oddly enough.
