DavidEduardo said:Yet that does not seem to have affected WBZ's ratings performance, which is quite superior to that of WRKO.
That can be summed up pretty briefly: WBZ's news content all day and evening local talk is locally very popular, more so than WRKO's mostly syndicated fare; their signal is strong at all times throughout the metro (WRKO is directional at night and misses 1/3 of the market). Basically, WBZ is THE place to turn for local news and traffic at all times while Entercom has cut WRKO back to having just a couple of local shows.
So, it's a matter of content AND signal. Comparing the ratings of the two is apples and oranges. But, WRKO's audio is much better because they use all 10 kHz for analog. It's louder and clearer and provides and excellent example of how a station running AM HD doesn't "sound as good" as one without it.
