[Discuss-gnuradio] WWVB monitoring with GNU radio

2014-03-15 Thread 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
