[R-390] OT: 15 MHz WWV Spurs

[Tom Norris]

Mildly off topic, but at least radio related to a degree.

For the past couple days, NIST has been running a dirty transmitter!

Folks on various other mailing lists are reporting reception from all
over the CONUS of spurs at +/- 26 KHz from WWV's 15 MHz
frequency. I can hear them here at 14.974 and 15.026 at about S2
to S3, making it only down only around 40 dB from the main signal at S9.
( My HP 8640B generator confirms the S meter to be sort of mostly
accurate on my Icom 756 Pro, I double checked) Heck of a strong signal
for such a boo boo, VOACAP calculates S2 to be around -8.16 dBuV, that
calculating out to be about -115.5 dBm, or around .39 microvolts. (I was
bored, sorry) Especially bad is that NIST is the one making the boo boo.
Maybe I am being so hard on NIST because I work for a cal lab, dunno.

Take a listen Friday during daylight hours and see if it is still there.
I it is on its 2nd or 3rd day of being there,  and you'd think they would
have it fixed by now.
