Hi Ron,

Hmm... I see what you mean; they no longer list a receive-only model. After
they stopped offering kits, they did still show a receive-only, totally
built version (which is what I bought in January).

I know that Flex just disables the transmitter portion of their 1-watt
transceiver model, and sells it as receive-only. I believe you can
specfically ask to buy the receive-only, and they'll just sell you the $925
1-watt transceiver with the transmit parts disabled. They may also remove
(or not include) the cooling fan; mine has just the grill in place with no
fan behind it.

As you might imagine, 99.9% of their customers buy the radio for 2-way use,
so that's what they feature on their site. I'm sure you can still get a
receive-only version, but it's evidently by request.

By the way, from what I've been reading on their e-mail reflector, their
customer service is top-notch, rivalling the experience I've had with Drake
and AOR-UK in the past.

Your past postings re the FlexRadio SDR 1000 aroused my interest but when
I go to their web site I do not see the receiver only version listed.
Have they given up on this option?

This two-night trip to Grayland turned out to be 95% tropical bands
DXing, as I found very little to get excited about on the medium wave
frequencies. There was some moderate geo-storming during the evenings
(particularly 4/9), but I don't know if it was my lack of Beverage
antennas or the propagation to blame.

The tropicals were far more productive than the meager catch of TP
regulars listed below. Best catch was R. Diff. TV de Djibouti on 4780
with an ID, heard via longpath 1-1/2 hours after Grayland sunrise and 1/2
hour prior to Djibouti sunset. Botswana and Zambia were also logged
during morning longpath.

Since I was staying at Grayland Beach State Park (1/2 mi. south of the
Grayland motel venue), I was limited to antennas that would fit on the
campsite (the few newer campsites at Grayland suitable for very short
Beverages were already reserved months ago). I can only wonder if the
noise would have been lower had I been in the new, expanded section of
Grayland, where campers are a bit further apart, and a few sites allow
for a few hundred feet of wire strung through the brush.

I used two newly-acquired antennas which complement each other well--the
Wellbrook ALA 100 and the tiny PA0RDT "Mini-Whip" (about the height of a
pencil). The antenna is powered through the coax (like the ALA 100) using
a small interface box mounted near the receiver. The antenna and the
well-built interface box are sold by Dutch NDB enthusiast Roelof Bakker,
PA0RDT, for just 43 Euros (shipping to USA included). I think Roelof may
have tweaked the antenna element to produce better results above
longwave, based on some other information I've heard. By the way, this
antenna uses an overload-resistant amplifier designed with some advice
from well-known Oregon NDB'er Steve Ratzlaff.

The ALA 100 was in a 40-ft. circumference setup the first night, and the
second evening I moved the poles apart and restrung the loop for a 54-ft.
circumference. Both nights the null was oriented toward Seattle. I used
two, 20-ft. "Black Widow" collapsible fishing poles as supports.

I mounted the Mini-Whip at 27 feet high on the second-to-last section of
a DK9SQ mast. The generous height helped the gain, as its designer Roelof
Bakker indicated it would. John Plimmer in South Africa mentioned that
the Mini-Whip is very prone to electrical noise, and I'd have to agree
that it's a real noise magnet. However, I was very impressed with it's
performance throughout medium wave up through the tropical bands. The
gain drops off quickly above 9 MHz or so compared to the ALA 100. On
medium wave the 5-inch long Mini-Whip kept right up with the Wellbrook,
and many times was the antenna of choice. On some parts of MW though, it
was considerably noisier than the Wellbrook (my campsite was near a
number of RVs with TVs, light dimmers, etc. all polluting the bands). I
think the Mini-Whip would have been the equal of the Wellbrook if I had
been in a totally RF-quiet area. (Hmm..I wonder if a 1:1 isolation
transformer between the Mini-Whip's power interface and the receiver
would help reduce noise?)

The ALA 100 was impervious to 99% of the noise, and at times was
*extremely* impressive. However, on the tropical bands the Mini-Whip was
the preferred antenna with better s/n ratio. I didn't have opportunity to
experience the Mini-Whip's reported superiority on longwave, as the local
noise and RFI buzzing was so bad below 500 kHz.

Both antennas are easily transportable and great choices when space is at
a premium. Please check my blog site in a couple of days for some photos
of these antennas, and also a few MP3 audio clips of DX from the trip to
Grayland (the tropical band logs will be posted there, too).

The SDR-1000 showed its superiority over my modded R-75 nearly every
time, although there were a couple tropical band frequencies where the
ICOM was clearly the winner. I *really* like Jeff, WA6AHL's new version
of the PowerSDR software for the Flex-Radio, with filter controls and
operation that fits "my" DXing style, and the expanded panadapter of 85
kHz with panning and zooming features. The panadapter itself is far more
useful than the "stock" PowerSDR software from Flex-Radio. Screenshots
and comments will also be posted to the blog soon.

On to the few TP medium wave loggings:

------------------------------------
558 JAPAN JOCR, Kobe, Apr 10 1307 - Japanese female pop music tune to
1310 female announcers in Japanese. Korean language heard in background,
tentatively HLQH, KBS 2. Fair level. (Atkins-WA)

594 JAPAN JOAK Tokyo, Apr 9 1220 - Slowly building signal at tune-in
1220, with lively Japanese conversation with male and female announcers.
Numerous mentions of Tokyo. Fair to good level. Best reception in the
SDR-1000's Binaural-SSB mode, which spreads the noise frequencies
left-to-right on stereo headphones, allowing for better concentration on
the voice frequencies. Also noted 4/10 with a strong signal at 1322.
(Atkins-WA)

612 AUSTRALIA 4QR Brisbane, Apr 10 1318 - Male and female announcers with
talk in Aussie-accent English; mentions of Brisbane and Adelaide.
Parallel to a weak 774 3LO Melbourne. Fair to good level. (Atkins-WA)

612 NEW ZEALAND 3XG Radio Rhema, Apr 9 1334 - Tentatively 3XG with choir
music, male announcers in English with Kiwi accent. Seemed to be
discussing church matters. Weak signal. (Atkins-WA)

667 UNIDENTIFIED Unid, Apr 10 1315 - Weak, QRMed signal, too messy to
identify language 100%. Seemed Japanese or Korean. (Atkins-WA)

774 JAPAN JOUB Akita, Apr 9 1235 - Strong signal of male announcer in
Japanese, and parallel to 828 JOBB Tokyo. Scraps of Aussie-accent English
in the background, possibly 4TO Townsville. (Atkins-WA)

828 JAPAN JOBB Tokyo, Apr 9 1248 - Fast-paced interview or radio drama at
a very good level. Parallel to 774 JOUB Akita. 3+1 time pips and NHK2 ID

back up at 1303. (Atkins-WA)

873 JAPAN JOGB Kumamoto, Apr 9 13012 - Weak signal of male talk in
Japanese, and parallel to 828 JOBB Tokyo. (Atkins-WA)

891 AUSTRALIA 4TAB Innisfail, Apr 10 1332 - Right at tune-in I caught
'Radio T-A-B Australia' ID at 1332, followed by man and woman chatter in
English. Good level, but faded quickly. Is this their typical ID without
the '4' in 4TAB?. (Atkins-WA)

891 UNIDENTIFIED Unid, Apr 9 1344 - Very weak signal of two male
announcers in English, possibly Kiwi. Perhaps 2XW, Wellington? Stayed
