Topband: 1820 spur

[Shoppa, Tim]

At my QTH (suburban Washington DC FM19ka), I do not hear a steady carrier at 1820, but instead would describe it as a raucous cacaphony of buzzsaws from 1820-1827 or so, especially in evenings.

What's funny is that right below 1820 it clears up. So for example the Thursday night sprint which happens around 1815, I am not at all affected. But it in the Stew Perry, there's a lot of not-strong-signal activity between 1820 and 1825 that I have to miss.

It is vaguely similar to the NJ 1810 noise cleared up last week, but much broader and not nearly as loud and for me. Unlike the NJ 1810 noise it seems to go away during the day.

1820 kHz is also 4 times the common 455 kHz IF.  You could be hearing
your own receiver(s).

As a teenager, I used to listen to a 910 kHz AM station in Portland, OR,
and some of our household 5-tube AM radios had beat notes from 2 x 455 kHz.
