ALL of the 10 KHz frequencies are bad somewhere in NA, and the same issues apply to the 9
KHz spaced MW stations in other parts of the world.
Second harmonic, and regular ordered products abound. Example 980+840=1820
These products/harmonics are generated in lots and lots of things, from our
At my QTH, many of the local (just a few miles away) AM BC stations cut back
power a lot at sunset.
The cleanup is remarkable on my transmit Marconi. Before sunset and without any
reject filters, I literally have 50V RMS between antenna and ground. It can
light up a neon light on modulation

We can be sure it is not a harmonic of an IF. :-)
1820 is a particularly bad frequency because it involves 2nd harmonics of a
popular

There are about 116 AM broadcast stations in the U.S. using 50 kW
transmitter power during the day. Some of them reduce power at night,
however KFMB (760 kHz)

I did a search and haven't found any previous comments on this reflector
about the Shared Apex Loop Array.
Has anyone tried it yet?

Topband reflector -
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

I put up a 160m dipole but now need to tune it. SWR at low end of band is abt
3 and at top end abt 5. From what I have read this means I need to shorten it.
My question is how much should I take off? A foot off each end?? Any good links

Hi, Tom;
Perhaps you can take a portable transmitter and manual tuner to the site. At
the point where you wish to place an L network, attach the manual tuner and
transmitter and adjust the tuner for a good match. Take the tuner away from
the source of interference, put a 50 Ohm dummy load
