Yea, that’s what I thought, too.
Want to know something really funny?
Back when commercial radio started, hams had access to what is now the AM band - and frequencies below.
When the US Navy (who was the first federal agency given control of the airwaves) decided that only medium and low frequencies were of use, the Navy took control of about 2MHz and below, and gave everything else to hams.
Sadly, we hams then went on to show the government bureaucrats just how useful the higher frequencies were, and they came back for them.
And a lot of those ‘ham’ stations morphed into commercial stations, once the industry matured a bit, and the Commerce Department began to get the idea and issue commercial licenses.
In the meantime, one of the Commerce Department’s not-so-forward looking ideas at the beginning of the 1920’s was to put all stations on exactly 360 meters (833 KHz,although they used wavelength back then). I guess they didn’t foresee that more than one party every thousand miles might become interested in setting up a radio station. Of course, they got past that idea pretty fast.
