Here in Western WA, KIRO/7 just ran its own crawl informing viewers that dish would remove KIRO's program signal at 4 PM PT - right around the end of the Michigan State-Duke game currently in play. Nice.
RETRANS SPAT Rule #1: Don't call dish. It won't help things.
RETRANS SPAT Rule #2: But if you do, call the station and let them have some of it.
RETRANS SPAT Rule #3: If you can, put up an antenna. (I have and I can get KIRO from a local translator station)
BTW: This spat will also affect viewers of Cox Media stations in Dayton, OH and Jacksonville, FL, both of which are CBS-affiliated.
One more thing: make sure your internet is paid up and in working order, especially if it's high speed. You may end up needing it for final four 'streaming'.
