[Lf] AMRAD LF Active Antenna

[Frank Gentges KØBRA]

Hi,

As many of you are aware, several of us in AMRAD have been working on an 
active antenna for LF.  That project has produced a design that we think 
can be built by the  Radio Amateur or LOWFer in his home workshop with 
ordinary hand tools.  We have arranged for PC boards to be made available 
from FAR circuits to simplify construction.

A construction article is scheduled to appear in the September issue of 
QST.  We have added a new AMRAD LF Active Antenna web page to our LF web 
page with a sneak preview of that article as some of you have been asking 
for more information.  We will add more information we have.  QST ended up 
giving us a whole lot of space but as always, there is still more... file 
folders more.

You can see our new AMRAD LF Active Antenna page linked off of our LF web 
page at <http://www.amrad.org/projects/lf/>.

In addition, we have permission to post the technical manual for the Cubic 
R-3030 from the fine folks at Cubic <http://www.cubic.com/cci/index.html>. 
The R-3030 goes from 5 kHz to 30 MHz and works really great down at VLF and 
LF.  It is available on our web site for download and is almost 6 megs in 
size.  It is worth the download just to study their design.  They do show 
up at hamfests so keep your eyes open.

Frank
