hi Eric:

Oh, I don't argue *that*, I just argue that it wasn't resonant.


if you knew that then why use this antenna for LW?

Not that it matters, really, my WR-G303i reports its signal strength
as 30 mV 120 miles away on a 400 foot wire broadside to the antenna.
Flamethrower, indeed.


30mV at what frequency? can you fault the R8B and R75 for overloading?

Dunno. I don't keep up with the local doings of the broadcasters
much. I assume they are in the old standard TV UHF band; 47 CFR 369
says that from 470 to 890 MHz, field strength on Table Mountain must
be less than 30 mV/m.


that PAR LPF should severely attenuate UHF. spectral analysis of that wire
is needed. low frequencies or potent RF energy can cause PIN diodes to
rectify.

No radio is perfect; the '7030 wouldn't hold up out there... To me
the question would be whether or not the '340 would.


the 7030 uses an SD5400 first mixer and has 40 dB of attenuation on tap...
add a $50 homebrew LW BPF: your RX340 will overload first. either way an
R75 hooked to a LW loop will hear more NDBs.

Eric, you remind me of Captain Ahab, fighting that whale of an antenna,
Moby Dick. man versus nature, a classic... but the SOB already bit off your
leg. shake the obsession... build a LW loop.

regards,
phil
