[BC] need a NON-technical explanation

With broad-band spark transmitters, your frequency was the resonate  
length of the antenna...

A 300 meter antenna radiated best at 300 meters. And even then the  
spark energy wasn't a carrier wave ( implying cycles or Hertz )... it  
was more like IbUZ.

Therefore, "I'll be on 310 meters" was where the antenna radiated best.
Everybody ran different length antennas to keep from interfering
