I realize that we're very much off-topic but I'll add my two-cents worth.
Back in 1999, my former employer, WTVT Television, added HD to their facility.
They built a new tower because the old tower (which held the analog antenna) wasn't rated to handle the additional loading of another antenna system.
The new tower cost the company about $2.5 million. Additionally, they purchased new transmission line, transmitters (parallel configuration), air conditioning, emergency power generator, electrical distribution and switching gear.
It was a huge expense which added absolutely nothing to the station's billing. Zero ... Zilch!
I can understand how the forced conversion to digital could easily push smaller groups into bankruptcy.
We should probably bring this thread back on-topic.
I believe the relevance to the original topic, went to the history of a government-mandated transition to digital, or whatever flavor or broadcasting. The DTV migration is a good example, albeit controversial depending on your slant, to what could happen with radio during a digital transition. As you did Frank, I wanted to dispel the assumption that somehow TV broadcasters benefited financially, even perhaps on the backs of their viewers or advertisers through the transition, or that they lobbied the government to force the transition. That would the the furthest from the truth. I don't recall the DTV transition specifically bankrupting any groups, but it sure didn't help. Now a forced transition for radio to either an FM channel or all-digital operation? I can think of several mom-and-pop stations that would absolutely go under.
