The Katrina Information Network, developed by Washington-based Flying Colors Broadcasts, will be available to Dish customers free while the Gulf Coast is rebuilding.
The channel broadcasts updates from relief agencies as well as key information such as telephone numbers and a survivors' list, EchoStar said.
EchoStar also is working with Clear Channel Communications Inc. to transmit that company's FM radio signals from Baton Rouge, La., to New Orleans.
EchoStar Communications, based in suburban Englewood, is the nation's second-largest satellite television provider.
