  MEDIA BUREAU TO PERMIT USE OF ENERGY-SAVING AM
  TRANSMITTER TECHNOLOGY

  "By this Public Notice, the Media Bureau (Bureau) announces that it will permit

known generally as Modulation Dependent Carrier Level ("MDCL") control 
technologies or algorithms, have long been used by international 
broadcasters operating high-powered AM transmitters...."

  THE MT. WILSON REPORT BY DENNIS DOTY

  In terms of things happening on and around Mt. Wilson, roads crews are 
working on Upper Big T.  They're resurfacing it (again) and that means it 
should be open soon.

  On the other roads, CHP is still busting a ton of motorcyclists on the 
weekends.

  Enjoy the change of seasons and watch out for the other guy.

  two patents at the center of a legal dispute between radio
  broadcasters and the company claiming to own key automation
  patents:

  the tower often needs to be detuned to avoid warping the AM

  TV

  o  The FCC's deadline for LPTVs and TV translators to
  go all-digital is September 1, 2015.  That hard date has
