Hi Laurence,

They installed a 2.5 MW wind power plant exactly where i've done my=20
experiments in 2010/11. Obviously it is a good QTH when you need wind=20
:-) So i cannot use that QTH any more. I would need to find a new one.

I don't want to say that the VLF times are over for me, maybe there will=20
come another season sometime. A lot can be done! :-)

What about your location in AK? Is there no chance that YOU begin to do=20
some TX experiments, by using an "earth antenna" (uuuh, some excitement=20
grows in me when thinking back)? You should have the place to install a=20
very long one! You just need some wire, maybe 1...2mm diameter and some=20
100m long. A dipole would be interesting. Maybe you can use it for other=20
bands as well! If i would live close to a forest, a lonely forest (here=20
they seem to clean it and cut some trees here and there to sell them=20
periodically!), i would have such an antenna and i would add 100m pieces=20
to the ends from time to time :-)

With 700m wire and 250 W RF power i made 45km in DFCW-600. So if the=20
dipole ends are close to your home QTH (actually you can use a simple=20
long wire, not a dipole, then you will need just one /p ground made of=20
earth rods), then you can run 1 or 2 kW (or 3 :-) ) and your home earth=20
system is the first end of the radiator. 2 kW against 250W is +12 dB.=20
Since you are not limited in time (like me, when beeing /p with that=20
small generator), people can try in "DFCW-60000" or 47 uHz! Another 20=20
dB! :-)
And if you use a 7000m wire, is it then 10x the loop area? Would that be=20
another 20 dB? :-)

Maybe you can gain VE7BDQ or VE7TIL (you remember?) and some other=20
stations in a range below 1000 km for first tests! :-)

BTW without the need for a loading coil of several 100 mH there is no=20
sound that nerves the XYL so it's very friendly to  all :-)

Give it a try! +100m each week!

And keep us informed about the progress!

73, Stefan/DK7FC
