It's funny that it broadcasts the local time, with adjustment for daylight savings. This makes the receivers extremely easy to build, which mattered a lot in the times that the signal was first broadcasted. And a lot of receivers have been manufactured over the decases, probably tens or even hundreds of millions.
Today even the most basic microcontroller could easily adjust the UTC time to the user's timezone. If this was built today people would laugh at the idea of broadcasting anything else that UTC.
- foobarian 5y agoI love that it took a 35 horse power transmitter (with what, 20 making it out as EM radiation) to do it. That kind of power in a radio signal is just wild to me, especially because of what kind of components it takes to build the transmitter.
