Thanks for sharing this Wayne. That was our experience in SE Asia in
the 60's too, sans KX2 of course. If we could get the dipole 6-10'
high, we were good for both the day and night in-country nets and could
also work our HQ & Maintenance Depot at Clark AB in the Philippines 24
hrs. The problem with a 6' dipole was clotheslining a trooper in the
middle of the night. [:=)
Folks these days seem to be looking for the perfect [magic?] antenna and
are reluctant to just try a basic "non-buried conductor" unless it comes
with the magic guarantee first. I'm somewhat constrained by our HOA's
Architectural Review Committee [OK, nothing visible]. My 135' end-fed
wire along the wooden fence works surprisingly well at 100 W considering
it is just about eye level all the way. As good as 5 over 5 over 5 at
100' on 40? Not quite, but I can make Q's on any open band anytime I
want including DXpeditions where I wait a few days until the bruhaha has
settled down some.
Antennas are one of the last radio neighborhoods for the average ham to
experiment with, homebrew transmitters and receivers are rare these
days. It often could take less time to just "try something" as an
antenna than it takes for the endless arguments on email lists on what
works and how well.

I made a few small baluns out of binocular cores that are 4:1, which handle the output of the KX2 on Voice, CW and digital all day long. Typically the dipoles are strung up arms-reach-high in the field, which gives us easy 300 - 400 mile range in our KX2 nets. If we're fortunate enough to have a tree, that OCFD with a center height at 10 to 15 feet or so works perfect for NVIS, at least for us.
