Now you are trying to dictate to me what to do. That
has not worked in the past. Are you dangling from your Kite and when do you
expect to land !!!!!!!!!!!11

We all know that vertical antennas, as high as possible,
are the best choice if one has the place and if there are not to much trees
and buildings. No need for discussions. If there would be something better:
The commercials would prefer it. And of course QRO gives a better signal than
QRP, trivial.

I do not have a wideband RX so cannot help with
your request. Wrong! You have a PC with a Microphone
input that covers 0...24 kHz, wideband! You could simply take your RX loop and
feed it into the soundcard, maybe with a AF transformer for decoupling, just
as the most hams do it. The record distances above 2000km distance were
achieved by such systems so they obviously work. Instead you prefer a 10s year
old VLF RX that is drifting several Hz and feed the signal into the soundcard
at 1 kHz using SpecLab. WHY?
On VLF my max BW is 3 Khz, ideal for my
needs. But your RX has no noiseblanker and/or clipper
and thus you loose several dB in sensitivity! In summer you will loose >20
dB sensitivity without noise limiting.
All that can be arranged in
SpecLab and most are using these advantages!
It can't be to difficult
to take the cable coming from the RX loop and connect it to the cable of a
headphones plug and put it into the soundcard input, isn't it?

You have certainly got me puzzled.
!!!!!!!!!!
Earlier on this morning at 0253z you congratulated
Toni and Jay on their TA qso.
I was congratulating you on your achievement
with your TX Kite antenna and the distance covered and you
OBJECT.
Again the best signals so far generated and distance
covered have been from Vertical antennas, ie KITE, BALLOON and large Static
Ex Broadcast tower.
I have not yet heard/seen any VLF/LF signals from
EARTH TX induced or induction propagation. Are you telling me I
am wrong?
Has you Oscillator drifted off frequency
?

Re: LF: Antennas es power
Mal,
Are you bored? What's the motive to start that
thread? Making some stress and anger on the reflector?
Watch some
TV, look what's going on on HF, take a walk until its dark or take a
bath... There's much one can do :-)

A cave DIVER is someone who decends underground
for exploration. I was not referring to Sea/Ocean divers
I did say Cave Divers.
