Noise spectrum around 9330 kHz, 21:15 UTC 4 Aug 2012



Usually I don't loiter around 31 m in the afternoon, especially now that there is no DRM from Sackville on 9800 kHz, but during a quick scan I came across this weird noise structure. Can't imagine it's some electronic interference as I couldn't find any harmonics.



While I'm here, some comments about WBCQ out of Monticello Maine. From the waterfall, it looks like it's trying to do upper sideband with carrier. But there's still a visible LSB, about -15 dB relative to the USB. Unless it's suppressed by like, at least another 10 dB (-25 dB total), I don't see a point other than to troll anyone who doesn't have synchronous / product detection.

Then again, most of the content comes across as a giant troll, but it pays the bills so whatever.

Also, the carrier is not even on 9330 kHz. It's usually about 33 Hz higher, but it can sometimes be below target. And lastly, it experiences complete loss of audio for several seconds at a time, as if a resettable fuse is constantly tripping. Run more bible thumping anti-science/anti-government/anti-anything programs and get better broadcasting equipment. Or don't.
