[Discuss-gnuradio] WWVB monitoring with GNU radio

[Louis Brown]

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.
