Topband: RFI / Interfering Phenomenon?

[Eddy Swynar]

Hi All,

Many thanks for all of the responses to my original query of this morning...

General consensus has it that the noise here is some sort of switching power supply, possibly linked (according to SEVERAL respondents) to an exercise treadmill. 

It ONLY starts at 7:30 AM sharp, so it is most definitely NOT related to a furnace (it gets pretty cold here in "VE3"-land during the night---why would a furnace only start doing its thing that late in the morning, right...?).

The good news...? Well, if it IS, in fact, an exercise machine, I suspect that the noise will ebb, along the very same lines as the enthusiasm of the user! Hi Hi. And such enthusiasm for steady & regular work-outs seems to wane a lot faster, than it does slower...

BTW, for those who suggested it, the QTH here is in the country---NO industrial sites / facilities for many miles here, and of those that do exist, they are all miles to the south & south-west of me---and the noise peaks from the north.

I am still curious as to the exact closure of the noise, too, which I have yet to do...

Thanks again to all respondents---your thoughts are much appreciated here.
