I am a ham. This is a nice, very educational project that a couple of kids could use to communicate between their adjacent bedrooms at night. It probably provides less rf than a typical noisy LED lightbulb power supply. The instructions show how to set the frequency between any local AM stations. If you are worried about neighborhood rfi, listen for it on your AM car radio in the drive and cut back on the length of the one meter antenna until you can’t hear it. Also, notice how loud the radio frequency interference (RFI) actually is between stations, due to power lines, passing vehicles, LED and fluorescent lighting, many other sources due to modern technology, and lightning and other atmospheric effects.

Communicate worldwide with Morse (hams usually call it CW, for “continuous wave”)![1] [0] https://www.ecfr.gov/current/title-47/chapter-I/subchapter-A/part-15/subpart-C#15.221 https://www.ecfr.gov/current/title-47/chapter-I/subchapter-A...
