Hi Chuck, 


Its nearly impossible to hide those old Wullenweber arrays, even if they've 
been dismantled for nearly fifty years

I was in the radio direction finding group at the U of IL in the early 60's which had a Wullenweber site just west of Champaign-Urbana IL 120 antennas in a circle outside a screen supported by telephone poles. The locals had colorful ideas of what it was all about. You could listen to WWVH, Hawaii and WWV in MD separately on the same frequency by rotating receive about 180 degrees. Very impressive.
