I am impressed by Casio engineers who created tiny antenna for my wrist
watch. I don't know how, but that Pathfinder able to catch and decode 60
khz wwvb in noisy city environment. And it did even better when i was
500 km north !

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.
