In this document, the Federal Communications Commission (FCC or Commission) partially grants a petition for partial reconsideration of the Emergency Alert System (EAS) testing requirements that apply to Satellite Digital Audio Radio Service (SDARS) providers filed by XM Radio Inc. (XM), as subsequently modified by XM's successor in interest, Sirius Satellite Radio Inc. (Sirius XM), and amends the EAS testing requirements that apply to SDARS providers.
