My experiments with WWVB crystal sets suggest it should be an easy
project. My WWVB crystal set consists of a long wire antenna and
ground feeding a tuned antenna circuit, inductively coupled to a
detector tuned circuit that is demodulated by a germanium diode.
During nighttime reception the diode output can be heard (without
amplification) in a balanced armature (sound powered) headset.
During daylight hours signal strength is somewhat reduced requiring
audio amplification to be heard.<br>
<br>
The biggest hurdle to overcome during the August solar eclipse will
be thunderstorm static crashes which can completely override WWVB's
signal. Whatever receiver design is chosen I suggest employing a
narrow bandwidth.<br>

" Keep in mind that not all RCCs (radio controlled clocks) are
created equal, some employ<i> advanced digital signal processing
techniques</i> that will allow them to synchronize under
conditions where other products will fail.<br>
