If you live within the coverage area and
your WWVB clock is unable to synchronize, it usually means a source
of radio interference
is near the receiver. Some common culprits are computer monitors
(some have a
scan rate at or very close to 60 kHz), noisy AC wiring, fluorescent
lamps, or nearby power
lines, transformers, or radio transmitters.
Also large soundboxes, machinery can disturb the signal.
I also experienced an unusual problem (because its unusual to have so
many receivers): I positioned 3 receivers with antennas tuned to the
same frequency in a line with a small distance between them. Then they
disturbe each other. Around 10 cm (4 inches) distance between them
solved the problem.
