[Elecraft] 80M on KX1

[Paul Huff]

Hi Tom,

I assume that you are talking about an easily deployable field antenna.  For 
convenience it's hard to beat a simple length of wire with a few radials on 
the ground.  I don't have 80-meters on my KX1 but I use a 42-ft wire for 40, 
30, and 20.  Of course that length won't help you, but here's the idea... 
Sometimes, because of the specific setup situation (angle of the antenna, a 
dog-leg in the wire, nearby structures, etc.) I am not able to get a good 
match with the ATU on all of the bands.  So I used some hookup wire to wind 
a coil on a plastic film canister and made taps about every-other turn.  If 
the ATU can't find a good match by itself I add in my coil between the rig 
and the antenna wire.  It doesn't take very long to find a tap that keeps 
the rig happy.  Something similar with a longer piece of wire might work for 
you.

Good luck and 73,
Paul - N8XMS
