Over the last couple of weeks on our TLARC Radio Net (Wed, 7pm, 442.1) I've
been making a quick mentions of technology topics that might be of interest
to others.

BACKGROUND: This week I quickly described the benefits of utilizing a
receive-only antenna on HF to improve reception while using the main antenna
for transmit. I learned of this technique from W5JAY, a friend who has used
it quite successfully on the HF bands. Based on his illuminating direction,
I purchased the ARRL book called "Receiving Antennas" and enjoyed it
immensely. But alas I thought that a large farm-like field was necessary
for such a 'beverage receive-only' antenna, and I quietly set the book aside
in my technical library.

However I recently came across a mention of a small R-O antenna detailed at
the KK5JY site. So this week I've been experimenting with his 15'-square
loop on the ground (LoG), just laying on the grass in the small-lot backyard
that I have here. Along with an easy impedance-transforming box, I was able
to plug this LoG into the back of my K3 and ... I indeed experienced an
improved SNR on my QSOs. Quite unexpected, but it works for me in a
somewhat RF-noisy neighborhood.
