[time-nuts] WWVB: measuring local 60 KHz noise

If you have a sound card capable of sampling at 192 kS/s, you don't need an SDR
to receive a signal at 60 kHz... just connect the output of an active antenna, like
e.g. the mini-whip, directly to the Line-In of the sound card, then use, for example,
HDSDR as software, setting the sampling frequency of the sound card to 192 kS/s,
the LO to zero, and the TUNE to 60 kHz.

I used this method in the past to successfully receive the SAQ transmission at 17.2 kHz
