A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

This is basically how radio controlled models using FM TX/RX pairs were coordinated back in the day, there would be a board with each frequency crystal that you would use for your transmitter, and you'd plop the matching one into your model. Reason being that if someone was already flying something and you turned your radio on to the same frequency, they would immediately crash.
