I saw this on another forum
Note to self: teach morse code to friends, communicate SAT answers with friends using 18khz tone.
Now if kids did that, they would truly be resourceful and they would at least learn CW morse code. Of sourse bands have been known to hide CW messages in a high pitched frequency in their albums before.
BTW - Solution to the above problem is obtain device that translates high frequency sounds into lower frequency sound that us old farts can hear and can detect loction of sound source.
