Absolutely correct Gary. Beverage, Hansell, and Samuel W. Dean were giants.
Hansell went to DR. Pierce, who successfully had a crystal into oscillation
in his Lab. (Pierce oscillator) Hansell got a crystal needed to heterodyne
the very low frequency of 5XX to either 5354 or 2677 KHZ. This allowed
automatic retransmitting of 5XX without level or demodulation problems. Then
he eliminated one sideband, making it the first commercial crystal
controlled single sideband
relay transmitter. Hansell also invented light fibers, that did not catch
on until more recent years.
Dean was the Radio Corporation of America engineer-in charge at Belfast when
they made the March 14, 1925 first successful double relay re-transmission
of actual radio programs from London.
Dean went on to Houlton, Maine where he installed, the first trans-Atlantic
radio telephone for AT&T. Dean was a licensed ham 1ZD (Dept of Commerce Feb
1915 NO2), and was a charter member of the ARRL. He died early in life,
after a trip back from the UK, from a strep throat that turned into a lung
abscess.
1XAO, Belfast in 1926 had three 10 mile Beverage antenna spaced 6 miles
apart. Some kind of an atenna array!
Have been researching the Belfast, station since April 2000.
