When I lived on my ranch, 2,500 FT above sea level, I had
a 2,000 Ft rhombic. I picked up all sorts of sounds on LF and VLF.

One of them was a 10Hz shift - but it was going at CW speeds, not
RTTY or something like that.

Trouble strikes in "series of threes" - but when
working around the house the next job after a
"series of three" is not the fourth job -- it's
the start of a brand new "series of three".
