Re: [IRCA] How local IS WBZ?

["CHARLES HUTTON" <charlesh3@xxxxxxx>]

IBOC is touted as having a power advantage, as it should be. The question is 
only how much of an advantage.

And indeed the hybrid mode doesn't support using 1/2 the analog power. The 
hybrid mode isn't even a fair comparison for coverage as too many technical 
limits are there to protect the analog mode. I extrapolated the power used 
in the hybrid mode and pretended IBOC performs the same in all-digital mode. 
That's a stretch, but good enough for a rough guess.
