    Not everyone has the same use case.

    As opposed to a chart.

    I get what you mean, but look at it. It's horrible.

AM radio, FM radio, amateur radio, and television broadcast have quite a lot of spectrum real estate. Are they being used enough to justify this allocation?
- christiangenco 2y ago
  Television in particular seems ripe to be reallocated. Didn't we go through a whole analog-to-digital conversion over a decade ago that led to TV going through wires instead of through the air?
  - jvanderbot 2y ago
    The digital signals are still radio-carried, but yes, that would technically allow condensing the spectrum some.

    Much of the TV spectrum has already been reallocated. Channels 70 to 83 to 1G cellular in 1983. Channels 52 to 69 to 4G cellular in 2008. Channels 38 to 51 to 4G/5G cellular in 2017. The current allocation is channels 2 through 36. Channel 37 is not used.

      Huh I didn't realize that. I grew up watching Fox on channel 49, one slice of history gone.

        Virtual Channel Numbers let a station pretend to be on a particular channel number. The actual RF channel number doesn't need to match. But the channel number you key in using your TV remote does need to match the virtual channel number.

        If I'm not able to watch my "Creature Double Feature" on the real actual channel 56, I just don't want to live any more.
