(AP) — These days, it isn't uncommon for a satellite channel to get into a beef with a carrier over whether its signal can be included on the menu. But not so usual for a channel to ask its viewers to get Congress involved. That's what's going on in the battle between The Weather Channel and DirecTV. TWC claims it could be a public safety issue if the channel ends up being dropped from DirecTV's lineup. The contract with DirecTV expires at the end of today. The Weather Channel is asking for  what it calls a "negligible" increase in what DirecTV pays to air the channel. For its part, DirecTV says it has other ways customers can get weather forecasts, including Weather Nation, a service DirecTV itself has launched.
