Some good links:
 

There was a post in RRS
http://groups.google.com/group/rec.radio.shortwave/browse_thread/thread/888a9daeddf2e52e/6d8a3c96169dad8c#6d8a3c96169dad8c
and the link to the Konsffjord DX page, which is a treasure trove!

In the section titled "The Dallas Files", files of projects by Dallas
Lankford, has several very
interesting and usefull items.

I found these links to be extremely interesting:

And RHF should find these links interesting. It was all I could do to
not run out and start
experimenting. But a T-storm is moving into the area so antenna
exploits will have to wait.
