Local Emergency Radio Service Preservation Act of 2004 - Directs the Federal Communications Commission (FCC) to revise its regulations to provide that digital audio radio satellite service (DARSS): (1) licensees shall not provide services that are locally differentiated or that result in programming being delivered to consumers in one geographic market that is different from programming delivered in any other geographic market; and (2) repeaters shall be restricted to simultaneously retransmitting the programming transmitted by satellite directly to DARSS subscribers' receivers.
Requires the FCC to complete a rulemaking proceeding to determine whether DARSS licensees should be permitted to provide locally oriented services on nationally distributed channels, taking into account, among other things, the ability of such licensees to afford listeners the same emergency and other information as is afforded listeners of local broadcast stations.
