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.
