Hey guys, how important is this guy? This is a bit of trivia I picked up 
about December 24.
My home town is Fessenden, North Dakota so ...
In 1906, Reginald A. Fessenden, a Canadian-born radio inventor,
broadcast the first musical program, accompanying on violin a female
singer's "O Holy Night," from Brant Rock, Mass. He discovered the
superheterodyne principle, the basis for all modern radio receivers.


Now where would we be without super heterodyne receivers? Let alone the 
concept of transmitting using a crystal controlled oscillator and a variable 
secondary frequency. That's what the Drake lines used, and a good reason 
they were so stable.
They had crystals for bands of coverage of 500Khz per crystal, both 
transmitting and receiving. :)
