Topband: RFI / Interfering Phenomenon...?

[Eddy Swynar]

Hi Guys,

I wonder if what I've been experiencing here is strictly a local case of RFI, or if others are hearing it to, especially at stations near southern "VE3"-land...?

Specifically, since roughly early December (when I first noticed it), at precisely 1230Z each day, & at around 1820-KHz, a loud "whir-whir-whir" noise suddenly starts up that is very raspy & broad...it can be heard at roughly 21-KHz spacings each way, up & down the band, and the entire "progression" very slowly moves down in frequency...

It's hard to put into words: imagine the whirring police siren from the film "Smokey & The Bandit", only with a very raspy / rough tone, and very broad. It peaks here with my K9AY that's pointing due north, causing me to suspect that it may well be some automatically timed gizmo that my gadget-crazy neighbour several hundred feet north of me may have acquired & "...put into action."...but then again, it could be something else, emanating from who-knows-where...

Is anyone else experiencing this right at 1230Z, or am I the sole lucky winner...?   :o)

My operations on 160 are not especially affected by this, as I usually pack it in around 1230Z, anyway---still, it HAS piqued my curiosity...
