Thanks for the info! Along these lines, how much to I benefit from =
having a
really good ground with my long steel wire antenna and my little DX-398? =
I
asked for a grounding rod last weekend at the hardware store in Spooner, =
and
I was a little surprised to find that it was about 9' long! I'll =
certainly
drive that sucker into the ground, but do I want to save this for when I
have my beacon put together? Or will it make a significant enough
contribution to my reception that I should hook it up right away?

Thanks again! What a great group!

PS

Ham University is a GREAT program! The method of instruction is perfect. =
I
was going to write a computerized, learning theory based Morse course to
teach myself, but I see it's already been done. I have been making =
steady
progress, and am even hitting about 50% correct on the Technician class
questions from Ham U--without having read any prep books yet! If my =
Morse
gets good enough, I may just go right for the General license!

	Steel wire shouldn't be a problem at all.  in Watt's "VLF
Engineering" there's a description of a huge VLF (~20 kHz) German =
station
(Gigante?) built during WW2 for communication with subs.  All galvanized
steel and the quoted efficiency is very good.
