I just received a couple of the KB-5 units from
a gentleman in Maine who makes them. As you
mentioned, I don't think the QB-18I transformers
are in production any longer. I got them on Ebay
many years ago. They are an 18:1 unit. The s/n
difference was what was really pronounced. I
live in a noisy area, which influenced my choice
with the ALA 1530ln. Living as far inland as I
do, I anticipated the need for amplification, as
quiet as practical. The ALA 1530ln was so quiet
compared to what I was accustomed to, that at
first I thought something was wrong with the
antenna. Further evaluation revealed that the
s/n of that antenna is simply head and shoulders
above anything I had used in the past. It was
just behind the Conti loop as far as apparent
gain and equivalent in the s/n category. I would
add that I thought that the s/n of either the
KB-5 or the QB18I was also degraded by the
introduction of the DX Engineering RPA-1 preamp.
The "cleanest", most intelligible signals were
with either the ALA 1530ln, or the other two
transformers without amplification. This was my
first go at a vs b vs c testing, with me
climbing up a ladder switching out antenna
transformers during the brief window of TP
signals present at this location. I must confess
that a Grayland session right after the 2006
IRCA Convention hosted by Pat Martin at Seaside
left a sustained and indelible interest in TP
dxing on me! While health and other
considerations influenced me to move back down
to town from the mountains where bogs and EWEs
abounded, I will continue to squeeze all of the
blood out of this "turnip" that I can, hi!

Interesting results
Craig.   It sounds as if the FLG-100LN isn't
functioning properly. (first thought...power supply?)
When you say "outperformed" was it in raw gain, signal to
noise or ?
I'm not familiar with either the KB-5 or QB-18I.Â
Are these no
longer in production?
best wishes,
Nick
