I remember the VOA station in Bethany, OH very well. When I lived in
Pittsburgh, PA in the 1960s (where I grew up), I could receive their
signal slightly above the upper edge of the 15-meter band about 21.475
MHz or so. Because of their proximity to my location, I picked them up
mostly on back scatter. However, every morning, I could hear some
meteor scatter on their signal. The meteors created a "whooping sound"
on their signal (because of the doppler shifted-signal heterodyning
against the backscatter signal). The reflected signal would rapidly
decrease in frequency. Once in a while, there would be a "blue whizzer"
-- the doppler shift would go down to zero, and their signal would "peg
the needle" for about 5 seconds or so.
Another effect I noticed on their signal was echoing. This happened
about 10 - 11 AM in the morning -- their signal would circle the Earth
three or four times. It sounded like they were in an echo chamber.
Yes, I had a good station back then -- my antenna was a 2-element
triband Mosley cubical quad. Those were the days (sigh).
