******************************************************************
    THE S.D. COUNTY POWER BLACKOUT OF SEPTEMBER 8 -- PART III
******************************************************************

  LESSONS LEARNED AT CLEAR CHANNEL COMMUNICATIONS

  According to John Rigg, Director of Engineering, Clear Channel Radio, San Diego, 
a number of technical things went well and worked right at their facilities when 
commercial power was lost in San Diego County's massive power outage of September 
8, 2011.

  The most unexpected and disruptive thing was the inability for employees to 
travel to various locations.  The roads around Clear Channel's studio complex 
were jammed with cars and trucks.
When the power went out, just about everyone in San Diego decided to go home at 
the same time resulting in gridlock for about two hours at Clear Channel's 
location.

  Insofar as emergency power generators were concerned, John said it would be 
helpful if government lightened up a bit on its air pollution regulations.  
Those regulations have become so onerous as to limit and discourage generator 
testing that is vital to ensure reliable backup power.  Without reliable power, 
the public will go uninformed in an emergency.

  To better prepare for the next major power outage, should one occur, John plans 
to add more transmitter site remote control features.  He also passed along this 
tip: "Two-way radio is king."  When cell service vanishes, stations need to rely 
on their own two-way systems, and he indicated that might include reliable old 
radios that are so simple we can fix them ourselves.

  ELEVEN MINUTES, START TO FINISH

  It took only 11 minutes, start-to-finish, for the events causing the San Diego 
County power blackout of September 8 to unfold.  Here is the sequence of events:

  TIPS FOR DISASTER COMMUNICATIONS

  The FCC and FEMA have issued a sheet for the general public entitled, "Tips 
for Communicating Before, During & After Disasters."  In our opinion, there 
are three very important tips that stations could promote over-the-air right 
now and they are as follows:

  (1)  When disaster hits, rely on broadcasting, not broadband,
  to gather information.

  (2)  If you need to send emergency information, anything
  goes, but for non-emergency communications use text messaging,
  e-mail, or social media instead of making voice calls on your
  cell phone.  That avoids congesting the network.  Data-based
  services like texts and emails are more efficient and are more
  likely to get through when the chips are down.

  (3)  In a disaster area, resist using your mobile device to
  watch streaming videos, or doing other ill advised stuff like
  downloading music, photographs and the like, all of which clog
  the wireless networks.  Stick with simple text messages like,
  "I'm okay, walking home from school, see you about 6."

  HIGH STANDARD OFF TOPIC MATERIAL

  Can neutrinos go a tiny bit (0.002%) faster than the
  speed of light?  The OPERA data so indicate.  This would
  upend physics if confirmed.
