Last weekend I joined my DXing buddy John Bryant at Grayland, WA for a
DXpedition that was first and foremost an antenna testing session, but as it
turned out the DX was definitely worthwhile for late August.

In his ever-prepared fashion, John had charted out in advance how the 700
foot Beverages and our Wellbrook Phased Arrays (prototypes) should be
arranged on the property. It must have been a more impressive (annoying?)
spectacle than usual, as I can't remember a time when more people asked us
about the strange wires than during this DXpedition. One Beverage and
Wellbrook array was oriented northwest (approx. 315 degrees) and another
Beverage and array was aimed due West (270 degrees). Center-to-center
spacing of the loops was 40m (~142 ft.), with their circumference at 60 feet
(20 ft. per side, horizontal leg at 3 ft. above ground).

The nulls of the arrays are impressively stable, requiring only occasional
(and slight) readjustment from top to bottom of the MW band for best
performance. John and I did some daytime groundwave testing of Portland
stations close in azimuth to the backside of the NW array, and observed
nulls between 38-45 dB (as measured with the accurate dBm signal meter of
John's g313e receiver). Stations that were approx. 20-30 degrees off-axis
were generally 18-25 dB down when the phaser's "reversal" switch was
flipped.

These relatively compact arrays are the first antennas I've encountered in
18 years of MW DXing that can compete with a Beverage! In nearly every DX
situation, reception was equivalent to the 700 footers, and sometimes the
arrays provided a bit improved splatter rejection, too. I'm looking forward
to comparing the arrays to much longer Beverage antennas in September.

My DXing on this trip was with my Eton E1, and occasionally John's E1 for
checking parallels. My SDR-1000 is on currently the garage workbench for
some substantial mods.

I recorded the following two MP3 files to indicate the performance of the
Wellbrook phased arrays. Each file starts out with 10 seconds of reception
with the E1 and the Wellbrook array, followed by 10 seconds with the
Beverage antenna, and then back to 10 seconds with the Wellbrook, etc.:

963 kHz: China Radio Intl. with their Russian language service:

891 kHz 4TAB Innisfail, Australia with sports talk:
http://www.guyatkins.com/files/8.25....ray_vs_bev.mp3

This file indicates the nulling ability of the Wellbrook array. It starts
with 10 seconds of 963 kHz, China Radio Intl. in Russian on the Wellbrook
with the beam switch in the NW direction, and then 10 seconds with the
reversal switch engaged (nulled signal), and then 10 seconds with the switch
in the forward direction again.

On to some loggings:


189 RUSSIA R. Rossi, Aug 26 1245 - Orchestral music, parallel to 279. Good
level, and quieter on Wellbrook array. (Atkins-WA)

531 NEW ZEALAND 1XPI Auckland, Aug 26 1252 - Church service with choral
singing in island language. 1XPI likely, on a local NZ Sunday evening.
Poor-fair; probable. At 1300, 2PM Kempsey faded up co-channel, with 'Radio
531, 2PM' ID, equal level to 1XPI. Buzz from an nearby IBOC transmitter was
a bit of a challenge while DXing 531 with the Eton E1. (Atkins-WA)

567 JAPAN JOIK Sapporo, Aug 26 1304 - Male and female announcers in
Japanese, with world news items. Parallel to 594 JOAK. Fair signal.
(Atkins-WA)

576 AUSTRALIA 2RN Sydney, Aug 26 1306 - Noted with jazz music and English
announcer, parallel to 792 4RN. Good signal. (Atkins-WA)

594 AUSTRALIA 3WV Horsham, Aug 25 1335 - Man and woman announcer with
interview of female C&W musician Elizabeth Cook. Discussion of her concerts,
followed by her hit song 'Sometimes It Takes Balls to be a Woman.' Some QRM
from JOAK Tokyo. Fair. Parallel to 612 4QR Brisbane at much stronger level.
Best signal by far on NW Beverage (!), just past local SR. (Atkins-WA)

612 AUSTRALIA 4QR Brisbane, Aug 26 1312 - Strong signal of an interview or
talk show discussing Solomon Islands politics. Parallel to 774 3LO Melourne.
