SES-LIC-20080714-00933, SES-AMD-20080822-01086 and SES-AMD-20090204-00145 Dear Ms. Dortch: Sirius XM Radio Inc. (“Sirius XM”), pursuant to Condition 197(d) of the above-referenced earth station authorization, hereby notifies the Commission that it performed emergency on-station telemetry, tracking, and command (“TT&C”) operations in the 4/6 GHz band. On Thursday, February 19, 2009, Sirius XM’s Quito, Ecuador earth station lost power at 9:47 p.m. ET (1/20/2009 02:47 GMT) and as a result both antennas in Quito stopped tracking and the telemetry and command links were lost. An antenna on the Ellenwood, GA earth station assumed the TT&C functions to the FM-3 space station (call sign S2105). The power to the Quito, Ecuador earth station was restored at 12:04 a.m. ET (1/20/2009 04:04 GMT) and the Quito antennas were returned to service shortly thereafter. Respectfully submitted, /s/ Robert D. Briskman Robert D. Briskman Technical Executive P.E. (DC) #8279 1221 Avenue of the Americas, New York NY 10020
