Here is an (almost) week long plot of WWVB signal strength taken with GR
and N210 + LFRX + 500 kHz LPF + 100 foot wire.  25 Msps decimated down
to 100 sps, then RMS to 1 sps.  Very strong -60 dBm signal here 500
miles from the TX, yet deep fades which are consistent after sunrise.
Surprisingly consistent reception during the day time.
