First time poster, accidently discovered this site, now I am hooked on sensorly.
I have a very good hunch as to where some signals are coming from...but might possibly be way off on this.
The sight on manhattan near harvey blvd could very well be the tower that belongs to the firestation on manhattan, 3824 is the exact address.
I also am looking at a tower by the other fire station for the same fire company, its address would be 2240 8th street. There has been crews working on this tower, although I do not know what they are doing. I am currently sitting about 100 yards away from it and not getting any LTE. Tomorrow morning I will check out the other tower at 3824 manhattan and see what I can find.
It's amazing how a simple "when will I get 4g" google search has turned in to an all out scavenger hunt; as if I didnt have enough hobbies already.
