Bruce - I'm on a 1 acre lot in the desert about 6 miles from downtown
Tucson and I have 2 AM stations within 2 miles of me. At night the
power drops and they don't create any problems. I do get some LW
intermod interference during the day but the preselector helps. I'm
using an old Grove TUN3 passive preselector with a few mods and a Ralph
Burhans design LW preamp between the preselect and receiver. It seems
to work quite well. I'm trying to figure out how to lay out a 1/2 mile
long wire into the local wash but I would have to cross someone else's
property! If you have a 100 foot or longer wire, hook a series
resonant tuner composed of a 365 pf varicap and a 5 to 10 millihenry
choke in series with the antenna and the receiver. It will do wonders
for impdeance matching and intermod.

Euro and N. Africa longwave was active again last night after 9 PM
local MST on 153, 162, 171, 180, and 189 kHz. In some cases there were
hetrodynes with multiple stations on a freq. with uneven, slow fading
such that one would dominate at times. Same story this morning with
the eastern Russian stations on 153, 180 and 189 kHz. The same
programming was on 153 and 189. Very strange rock music in English but
Russian announcer.

R70 with 150M long wire, LF preamp and preselector.

Hi, Frank - being in Tucson, are you relatively remote from most
domestic AM stations? Does that preselector help a lot?

I would love to listen to LW, but being near several blowtorches simply
does not help, for many reasons...
