"WWVB is hard to detect w/ a 3-foot diameter HP shielded loop w/ integral
preamp & 2 stages of mechanical filters. (HP 117A). The other half of the
time it was undetectable. Paul S uses a loop that is much larger."

I am near Chicago and I have 2 60 kHz antennas. One is a ferrite
rod type and the other a 5  foot diameter loop. Both are tuned 
and feed identical 2 transistor preamp. The loop does work better.
