Radio is dead... yeah. Or at least on life support.
The last time AM/FM simulcasts were a big thing, it was because FM was worthless and no one knew what to do with it but simulcast their AM signal.
Look when KOGO's current factility was licensed. How extensive was the populated area of the San Diego market?
In fact, 1240 was able to pretty well cover the market at one time. Today, the useful signal covers less than half the market population... between urban sprawl and increased interference, most AMs no longer cover their markets... including the earliest ones that are nondirectional or only moderately directional.
So, some AMs are dead and others are significantly hampered due to coverage. All are crippled by the increases in noise levels, resulting in limited listening by nearly anyone under 55 or 60.
Tell me: how are the gas stations and eateries along Route 66 doing ever since the Interstate highways started opening? This is just a change in situation that AM is just not able to survive.
