:-)) I have a 8 motor drone but can fly
only 20 minutes with one Kg payload.
A kite or baloon is better.
Seriously
speaking, the difficulties are very big,
as rightly says Stefan 160 meters
band, has a very different behavior but, do not forget that
in 1901 Guglielmo Marconi received a signal across the Atlantic at a frequency around 500 kHz and with a receiver that in comparison with
those of today was a tack. Ok were "only" 3500 Km.
Today what are we doing more
with our ultramodern equipment?
Today we have SDR, filters, DSP,
noise reducer, Marconi at Signal
Hill had a drop of
mercury.
Today obtain
a considerable power is
relatively easy and inexpensive,
114 years ago there were only Ruhmkorff coils then, how much power was actually radiated
no one ever taken the trouble
to measure it.
But as they did then my compatriot to get those great results: trying, trying and trying again
trying to improve
something every day.
The important thing is to think that nothing is
impossible, maybe improbable but not impossible.
Tonight I
bored with the history of telegraphy...:-)

Use a quad drone to hold ant wire up
More stable than a kite

Hi Stefan,
It would be interesting try to transmit
a robust CW signal
on 472 KHz,
eventually with a lambda/4
kite antenna on the saltwater.
It is a bit of
time I'm thinking... ;-)
Some years ago I made several
QSOs on 160m with VK and
ZL from my home
with the same 25m tophat antenna that I use for 630m.
Why not try also on MF ?

Hi LF,
It's time again to try attemps to leave
traces in VK. Edgar is running his grabber at https://dl.dropboxusercontent.com/u/101251787/testIDC.html
Starting
18:30 UTC, i will attempt to leave a trace in DFCW-180 there. The best
result so far was that: https://dl.dropboxusercontent.com/u/19882028/LF/Dk7FC%20ver%20o%20spec.png
Will
someone join in?
