MEDIA BUREAU PROVIDES GUIDANCE FOR CONTINUED PRESUNRISE AND 
POSTSUNSET OPERATIONS DURING MARCH 2008 BY AM STATIONS
IN AREAS WITH DAYLIGHT SAVING TIME
Daylight Saving Time (“DST”) commences at 2:00 AM on March 9, 2008.  Certain AM stations 
currently operate with Presunrise Service Authorizations (“PSRAs”) and Postsunset Service 
Authorizations (“PSSAs”).  Licensees with PSRAs and PSSAs located in communities with DST should 
use the April DST “Advanced” powers and time periods for the period between March 9, 2008, and 
March 31, 2008.  This adjustment is necessitated by the enactment of the US Energy Policy Act of 2005 
which extended the effective period for DST into March for the first time.
For additional information or to report potential interference which an AM station believes to be 
the result of PSRA or PSSA operation by another station during the DST portion of March 2008, contact 
Charles Miller, Susan Crawford or Son Nguyen of the Audio Division at (202) 418-2700.
