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.

   Another point is the noise that current high Voltage power transmission systems generate reduces 
the effective range of MW transmissions to far below that of FM transmissions.  Around here, central 
Florida at least.  I can listen to FM stations in the Tampa area all the way to Inverness to the 
North and Sebring to the South far past the AM stations.
I believe 100% of the 4,200 Volt distribution circuits (to all pole mounted transformers) have been 
replaced with 14 kV circuits.
   The proposal certainly has my vote.
