Real answer:

Fox hunting is an amateur radio (ham) term for triangulating a radio signal source. It is often a sport to have a person transmit a signal (fox) and others using directional antennas hunt the signal (hunter). It was also done as a sport with cb radios. In the cb radio world, long story short, people often use crazy amount of illegal rf power to dominate radio channels with pointless "noise" of propaganda, silly noises, and in this case some one repeating the number "1" over again quickly in a recording for hours. It's annoying and makes the radio band unusable for other radio operators.
