Topband: Looking for 160m narrow beam RX advice - an interesting combination of ideas

[Mike Waters]

A couple of thoughts here, good or bad:

1. I can see the case for an array of loops. However, wouldn't it be less
time-consuming --not to mention less expensive-- to just get an additional
MFJ-1026 to effectively null the second noise source? Null out one noise in
the first 1026, and then null out the second noise source in the second
1026? (If not in this case, then in other situations?)

2. I'm well aware that a separate noise antenna placed very close to the
RFI source can be extremely effective. However, if that's not possible,
then how about two identical RX antennas fed into a 1026? At one time, I
was toying with the idea feeding my main Beverage, and a second, parallel
Beverage, into my 1026.
The idea was to try and phase out distant line noise, among other things.

I have a 1026 here with most of Tom's mods, but I've never used it since I
moved here 10 years ago.
