hi Eric:

...what are you, totally thick or what? The MW station that was
causing the problems.

at what *frequency* is that MW station transmitting?

Of course. The R75 solves all. Can't imagine that if you use your LW
loop with another radio, that it'll outperform that R75, can you?
Come on, this is really simple. Take whatever crutches you add to
your R75, apply them to nearly ANY other radio on the market, and
it'll leave your R75 in the dust. (Notably, your dream radio, the
Racal 6790, would be left in the dust as well. What's your affinity
to radios with crappy front-ends?)

the R75 was used to drive home a point: ANY tabletop using the LW loop i
suggested will outperform your antenna. only you cannot admit you were
wrong. thinking is a crutch! rip on the 7030 and Racal all you want genius.
who could not figure out that a simple $50 homebrew LW BPF in front of
either will smoke your $4000 RX340 in terms of IP3, dynamic range, phase
noise, ultimate rejection, etc. explain how your radio will leave any
tabletop "in the dust" when both are hooked to a LW loop? quote specs.

670 kHz. KLTT. "The nations most powerful Christian voice." For
someone who keeps track of all the flaws in my past statements, you
should remember that one.

We'll see. I have no argument with using an LW loop, only with using
the R75.

Thank you, I think I will.

Tell me, phil, what's the hyping on the price of the '340? The
half-octave BPFs in the front end were only one reason I got it. Most
of the reasons I bought it were based on operating it and getting a
feel for how capable it was. Specs? You can look them up yourself.
I'm not a walking calculator. We can argue about 1, 3, 10 or 20 dB of
dynamic range for close-in spacing, but that isn't the issue. You
know that.

phil

hi Eric:

honestly i was trying to help. if you hook a large air-core air-cap [high-
Q] tuned loop to your RX340 you should be very happy with the results on
LW. you are correct, DR is not a big issue with this setup. if you hate the
R75 that is fine. one of the best out of the box units is the R8B. people
who say one cannot program listen or DX with the [insert tabletop name
here] are full of it. i've done experiments bearing this out. the tabletops
are more similar than they are different. buy whatever suits your fancy and
use the best antenna possible. i will call a spade a spade. the 7030 and
6790 have high IP3 mixers. AFA that 1000' antenna: 670-kHz is 3/4
wavelengths resonant at 1099'. radios are going to suffer from overload. i
suggest trying a series-resonant trap that: this should dump much of that
670-kHz energy to ground before it enters the radio.

phil
