Who among us is surprised? Almost all of the new technology tools (SDR,

make QSO's that would not otherwise be made. I personally have no interest in
working DX that way. It removes some of the challenge that drew

I was unable to get the antenna working today. Not really sure why because it
was tested extensively at home. Could be interaction with the tower. Maybe
just as good as some strong rain storms are moving through the area. I'll make
another attempt at it tomorrow.

Exactly right. Isn't small government wonderful? That's really not the
problem. Many federal agencies, including the one I work at, have plenty of
money and personnel. It's more a function of priorities and who sets them.

Seems like this is a matter of personal preference, where our
individual interest lies, and what motivates us to operate.
Some of you may know my attempts to activate XW on the lowbands these
past few years. My success on Topband to the US, most difficult path,
has been limited at best. It
Greetings - I thought I would share a few comments from the recently

Hi Gang - I was fortunate to be part of the HS0ZAR M/2 team for CQWW
DX CW. I arrived at the station on Tuesday afternoon, hoping the days
leading up to the contest a couple of us would be able to hand out
QSO's on the lowbands. A lot of work needed to be done in preparation
for the contest,
Hi Henk - we are using an 18 meter Spiderpole at ET3AA. It supports a
wire, using a Unadilla 80 meter trap (no longer in production), so
that it works on both 80 and 160 meters. I found while using those
traps at XW4ZW, that they cannot handle more than 900 - 1000 watts.
That is not an issue in
A couple of issues I see. It depends which direction(s) the noise and
desired signal are coming from. You may null the noise and signal.
Also, the loop is bi-directional.
I've been playing with a DX Engineering RF-PRO-1B at ET3AA and it
works. Thanks to Tim and the gang for their support. But
I would favor using an inductor. Tune it for the lowest part of the
band. Then using a relay or two, you can short out turns if you want
to move higher in the band. Although I think you will find using Rohn
25, it will be pretty broad.

Areas of my yard have a lot of stone. Six inch staples were a pain to
use. Four inch worked better, in case you have similar soil. Also, if you
are going to install a bunch of them, do yourself a favor and buy the
staple driver tool which makes it a breeze.

webSDR's are really fun to play with and great for testing purposes. But
you can bet the mortgage they are also being used for other less than
honorable purposes, especially on our beloved Topband.
