Not everybody has a digital radio. I have a '75 Porsche with an old Becker radio that has a dial. People actually collect these things and there are at least two radio shops around who will modify the old Becker to synch with my iPhone if I want to listen to Pandora or whatever. For the new stuff, you can go on Amazon and find dozens of portable radios with dials from cheap Chinese made units to more expensive units with shortwave, police and radio bands in addition to the old AM and FM. I just bought a brand new CC Radio from Amazon with an old style dial that was a knockoff of the old GE Superradio.You can post whatever you like that is within the board rules. But those of us who disagree can post our opinions.
Again, it has been about 3 decades or so since we got digital car radios and people stopped manually tuning radios that stunting has ceased to be effective.
When the only stations in a market were all on AM and at most there were 8 to 10 good signals, stunting got noticed. Since FM became dominant and those markets had 30 or more viable signals, nobody tunes up and down the dial. They set for the favorite stations.
Obvious question: have you ever managed or programmed a radio station?
Come to think of it, there is a direct tune knob on the digital radio of my new Honda CRV that lets me tune up and down the dial all day long looking for new stations if I want to. I'm sure I'm not the only one who uses that knob.
