OK. CBS decides to take 105.1 dark to protect KGIG. When would you figure KGIG might garner 1% of the audience in their coverage area?
Also ; wouldn't you figure that the 1% HD listeners of 105.1 are more than any possible numbers KGIG could ever get?
It depends on KGIG's format and how well they serve their community, I guess. Some LPFMs have decent listenership numbers from what I've gathered, if they're doing something unique and community oriented, or at least providing music not available elsewhere. It's entirely possibly KGIG has more listeners on 100 watts than 105.1 does in HD anywhere in the valley.
I'm curious by what the OP meant by "turn up the hash" - was the station already running HD and completed an upgrade for more power, or did it go from analog only to HD?
