Unless something has really changed, you shouldn't be so negative about
hearing SW on a crystal set.

About 1958, on a simple xtal set (antenna, coil, capacitor, diode, phones)
although I don't remember the exact stations (Quito and Radio Moscow?), I
do remember hearing LOUD shortwave signals. At the time, my antenna was
the top strand of a barbed-wire fence on wooden posts (length UNknown,
but probably less that a couple-hundred feet) and the ground was the guy-
wire to our house's power pole.
