[Elecraft] Elecraft] KX2

[Phil Wheeler]

There is a terminology issue, Charlie. The "EFHW" 
I use is this one: 
http://www.earchi.org/92011endfedfiles/Endfed6_40.pdf 
and is fed via a 9:1 UN-UN. Uses the coax shield 
as a counterpoise and seems to work well over the 
bands of interest -- depending on the length of 
wire used. An ATU is generally essential, and the 
one in the KX2 is very capable.
