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. :-) 73, Mike www.w0btu.com On Sat, Nov 3, 2012 at 1:15 AM, Robin <wb6...@socal.rr.com> wrote: > ALL of the 10 KHz frequencies are bad somewhere in NA ...
