Hi Dave,
If you want to check in with anyone in Oregon you may want to
change the orientation of your antenna. You are at right angles to the
main land or Asia with that wire the way it is now. There just aren't a
lot of folks north and south of you. Accept geography and try another
direction :)

Hi folks,
Newbie HF Dave here again with an end fed antenna design question.
I have an EARCH (Emergency Amateur Radio Club, Hawaii) end fed 6-40 meter
multiband HF antenna. Part of the design is the 9:1 UNUN (unbalanced to
unbalanced) toroid matching transformer. I have replaced the 30' wire with 66.5
feet of 18AWG Wireman silky 532. My end fed is in a horizontal (slight slope)
orientation, east-west. The antenna is about 50' above the ground (I have a 3
story house and pine trees close by).
I do not have an external antenna analyzer, yet.
Using the ATU in my KX-3, I have the UNTUNED SRW values below. With the KX-3
ATU, the KX-3 DOES tune all of these bands with no problem.
Question: Should I do anything to improve QRP performance, shorten/lengthen the
wire, or should I just go with the flow, hang loose and not worry and just
enjoy my rig?
REMEMBER, newbie Dave, be gentle. I've been tracking the long wire discussions
on the list, there is lots of fervor.
