Ha. My friend and I had the FCC van roving our neighborhood looking for us once, back in the late 70s. A guy with a CB base station dropped a dime on us, cause we were playing with our 0.1 watt walkie talkies near his house. The guy that sold us the handhelds said “what channel crystal do you want, how about 9?” and we said sure; we didn’t know that 9 is the emergency CB channel and the law prevents its use for, for example, playing hide and seek as a 13 year old.
