>=3B
>=3B Hi Laurence=2C=
>=3B
>=3B They installed a 2.5 MW wind power plant exactly wher= e i've done my
>=3B experiments in 2010/11. Obviously it is a good QT= H when you need wind
>=3B :-) So i cannot use that QTH any more. I wo= uld need to find a new one.
>=3B
>=3B I don't want to say that t= he VLF times are over for me=2C maybe there will
>=3B come another se= ason sometime. A lot can be done! :-)
>=3B
>=3B What about your = location in AK? Is there no chance that YOU begin to do
>=3B some TX = experiments=2C by using an "earth antenna" (uuuh=2C some excitement
>= =3B grows in me when thinking back)? You should have the place to install a=
>=3B very long one! You just need some wire=2C maybe 1...2mm diamete= r and some
>=3B 100m long. A dipole would be interesting. Maybe you c= an use it for other
>=3B bands as well! If i would live close to a fo= rest=2C a lonely forest (here
>=3B they seem to clean it and cut some= trees here and there to sell them
>=3B periodically!)=2C i would hav= e such an antenna and i would add 100m pieces
>=3B to the ends from t= ime to time :-)
>=3B
>=3B With 700m wire and 250 W RF power i ma= de 45km in DFCW-600. So if the
>=3B dipole ends are close to your hom= e QTH (actually you can use a simple
>=3B long wire=2C not a dipole= =2C then you will need just one /p ground made of
>=3B earth rods)=2C= then you can run 1 or 2 kW (or 3 :-) ) and your home earth
>=3B syst= em is the first end of the radiator. 2 kW against 250W is +12 dB.
>= =3B Since you are not limited in time (like me=2C when beeing /p with that =
>=3B small generator)=2C people can try in "DFCW-60000" or 47 uHz! An= other 20
>=3B dB! :-)
>=3B And if you use a 7000m wire=2C is it = then 10x the loop area? Would that be
>=3B another 20 dB? :-)
>= =3B
>=3B Maybe you can gain VE7BDQ or VE7TIL (you remember?) and some= other
>=3B stations in a range below 1000 km for first tests! :-)>=3B
>=3B BTW without the need for a loading coil of several 100 m= H there is no
>=3B sound that nerves the XYL so it's very friendly to= all :-)
>=3B
>=3B Give it a try! +100m each week!
>=3B >=3B And keep us informed about the progress!
