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 on

I have an inverted L about 16' above ground with many radials on my roof.
Would the K2AV FCP be effective connected as a "radial" ? I have a DX

can tune it to any band with my 3 KW Nye Tuner so I don't want to
Last week I posted:
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

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 1

There are multiple 910's around the country, its not necessarily the
same one. Been audible for as long as I've been in CO. Googling "am
stations on 910KHz" produced 38,100 returns. The first couple pages are
all K/W stations, I didn't look beyond that.
Likely every one of them can be heard so
One way to confirm that it is the BC station is to test the antenna during
the day then at night when the (most) BC stations reduce(s) power. You
might even be able to take a valid measurement when the BC station power is
reduced.

I wonder what these BC stations run at night - my local one on 1550 runs

I have a 2KW ERP station at 1480KHz 1.5 mi north of me and a 20KW ERP at 1300

I had the same annoying problem when troubleshooting my 160M phased
vertical array. Using the MFJ259, neither vertical seemed to have a
j=0 point anywhere near the 160M band, and the readings jumped around
a bit. I concluded that it was AM BC interference. There is a local

We can be sure it is not a harmonic of an IF. :-)

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 pea
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

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