Topband: 1820 spur

[Mike Waters]

I understand that. I have heard weak spurs on multiples of 10 kHz that come
and go on the low end of 160 ever since I put up Beverage antennas here.
But the one on 1820 is the strongest I have ever heard, and it's there
often.

And several times in the last few weeks, weak DX stations have chosen 1820
to call CQ. :-)
