[BC] Tower Location Change For WLAN 1390

[Jerry Mathis]

This isn't the answer you want to hear, but this is another GOOD case of why a new VHF broadcast band needs to be created, and Medium-wave broadcast stations need to migrate to it. MW broadcasting takes a lot of real estate for even a single tower when you consider the need for the ground system, and a directional array only compounds the problem by the number of towers required. VHF broadcasting will eliminate the need for multiple towers and nighttime power reductions for AM stations, just as it does for our current FM band.
