Good information. Another 23 meters would certainly help with building shadowing. There aren't too many 100 meter buildings in Minneapolis. From wiki: "Minneapolis, the largest city in the U.S. state of Minnesota, is home to 245 completed high-rises,[1] 34 of which stand taller than 300 feet (91 m)." http://en.wikipedia.org/wiki/List_of_tallest_buildings_in_Minneapolis The station transmits out of New Hope. If there is a tall building between you and the transmitter that explains the problem.
