=0A= >=3B
=0A= >=3B Hi Laurence=2C
=0A= >=3B
=0A= >=3B They installed a 2.5 MW wind power plant exactly where i've done=0A= my
=0A= >=3B experiments in 2010/11. Obviously it is a good QTH when you need=0A= wind
=0A= >=3B :-) So i cannot use that QTH any more. I would need to find a new=0A= one.
=0A= >=3B
=0A= >=3B I don't want to say that the VLF times are over for me=2C maybe=0A= there will
=0A= >=3B come another season sometime. A lot can be done! :-)
=0A= >=3B
=0A= >=3B What about your location in AK? Is there no chance that YOU begin=0A= to do
=0A= >=3B some TX experiments=2C by using an "earth antenna" (uuuh=2C some=0A= excitement
=0A= >=3B grows in me when thinking back)? You should have the place to=0A= install a
=0A= >=3B very long one! You just need some wire=2C maybe 1...2mm diameter and= =0A= some
=0A= >=3B 100m long. A dipole would be interesting. Maybe you can use it for= =0A= other
=0A= >=3B bands as well! If i would live close to a forest=2C a lonely forest= =0A= (here
=0A= >=3B they seem to clean it and cut some trees here and there to sell=0A= them
=0A= >=3B periodically!)=2C i would have such an antenna and i would add 100m= =0A= pieces
=0A= >=3B to the ends from time to time :-)
=0A= >=3B
=0A= >=3B With 700m wire and 250 W RF power i made 45km in DFCW-600. So if=0A= the
=0A= >=3B dipole ends are close to your home QTH (actually you can use a=0A= simple
=0A= >=3B long wire=2C not a dipole=2C then you will need just one /p ground= =0A= made of
=0A= >=3B earth rods)=2C then you can run 1 or 2 kW (or 3 :-) ) and your home= =0A= earth
=0A= >=3B system is the first end of the radiator. 2 kW against 250W is +12=0A= dB.
=0A= >=3B Since you are not limited in time (like me=2C when beeing /p with=0A= that
=0A= >=3B small generator)=2C people can try in "DFCW-60000" or 47 uHz!=0A= Another 20
=0A= >=3B dB! :-)
=0A= >=3B And if you use a 7000m wire=2C is it then 10x the loop area? Would= =0A= that be
=0A= >=3B another 20 dB? :-)
=0A= >=3B
=0A= >=3B Maybe you can gain VE7BDQ or VE7TIL (you remember?) and some other= =0A=
=0A= >=3B stations in a range below 1000 km for first tests! :-)
=0A= >=3B
=0A= >=3B BTW without the need for a loading coil of several 100 mH there is= =0A= no
=0A= >=3B sound that nerves the XYL so it's very friendly to all :-)
=0A= >=3B
=0A= >=3B Give it a try! +100m each week!
=0A= >=3B
=0A= >=3B And keep us informed about the progress!
