Here's a follow-up about Duncan from Dan Edwards, W5XZ who lived a time in
Folsom and now in Dallas.

W5DC, Duncan Carter. SK 6 / 6 / 12
Duncan was an EE; he worked for Collins, and Hy-Gain; later, he started
If you didn't know him, he was one HELL of a great guy...
First time i heard Duncan I was in Optometry School, in Forest Grove,
75m SSB. He was ridiculously loud and working JA's. around 1976, or so. I
idea we would later meet. I also did not know he was using a pre-cursor to
popular "4 square". His version was a parasitic array, with 2 driven
2 reflectors; spacing was equal at 0.2 wavelengths, and the array was 4
a square. " it minimizes the ground losses..." he used to say. 4 1/4 wave
tied in parallel at the center, and relays at the elements to select a
loading coil and
short a feedline, or select a feedline as a driven element.
Later, when i moved to Baton Rouge in 1979, we met. He liked the low bands
cw dx contesting, so we hit it off immediately. Duncan had a pre-cursor to
Flag' at that time, for 160m. He used a rotary pair of small, resonant
and introduced me to what is now called 'cross-fire' phasing. Mounted near
level, the 2 loops were on a pvc boom, which was rotated with a Ham-M. He
had a pattern like a 3 element yagi.....on 160m !!!
Duncan was a master at locating huge rolls of low loss feedline, and
Even though Duncan was a 'quad guy', he encouraged me to explore the
W2PV designs. I still contend Lawson's 4 element, 3/4 wave boom designs
the most db's for the least dollars. Duncan warned me about gamma
"it is very easy to match the losses, if you're not careful"...so I stuck
driven elements, and hairpin matches; the 4 / 4 stacks on 20 thru 10m were
real treat, back when I had 3 acres out in the country as a
kind enough to loan me his General Radio 1606a rf impedance bridge to help
understand the impact of guy wires on rotary, side-mounted yagis. Soon
I was ordering Phillystran...at least for the top half or so of my tower
I know Duncan was instrumental in getting Bob Taylor, WB5LBT (SK),
with a moonbounce array of quads on 2 meters. Bob was, i think, a 'rock
the moon, from his suburban lot in Baton Rouge. Duncan had magic fingers
long boom 2 meter quads....and we all knew it...
I also know Duncan was instrumental in developing some long boom HF quads
"Cajun Iron Man, Emeritus" W5WMU. Perhaps Dr. Sonnier can elaborate on
Later, we both left La. but stayed in touch intermittently. In his later
years he became
a "k-3 guy", ultimately assembling an entire ' K-Line '... When I told him
he was overjoyed. "the curse of the dx contester has been lifted !!!"
Never mind that I still haven't set mine up yet. He owned a microphone but
preferred CW...I'm sure he could send and copy 35 wpm in his sleep...
Duncan was a faithful spouse and father to his family. He was generous with
and resources. We will surely miss him dearly. If I make it, I hope to
upstairs one day... 73 Dunc W5DC de W5XZ sk
( i'm tearing up ......) "pay attention to the losses...." he always
