WJ-8711A HF
Receiver Installed in a "Hammond" Steel Cabinet
Welcome...
Here is my little spot on this earth to pass along my experiences
and or comments about "Radio Receivers", as well
as other gizmos that I use in my radio monitoring/recording
ventures. My main focus is in the "Shortwave" part of
the radio spectrum. A few other radio related items have been
thrown in too , including amateur radio equipment reviews and
views that may not be directly related.
I have been playing around with radio receivers for over 30 years
now, and in this time span my fingers have run across many models
(tabletops and portables), some really good and some really bad.
Most comments you read here have been pulled from my own head,
but I now have input from others as well (as noted). All
observations from me are being made with the 2 ear/2 eye method,
so no fancy test equipment here. These of course are my views and
your findings may well be different.
Any set being listed on these pages does not mean that I own or
plan on owning. See Dave's SW Receiver "Master List".
I'm sorry if any part of this site seems to have a
"Soap Box" slant to it , but I "tell it like it is"
.
Thank You for taking the time to stop by and most importantly for
your support. Enjoy your visit to my web site. Dave N9EWO.

- RFspace
has a new software defined receiver in the works.
Marked as the SDR-ONE. Check out
the Universal Radio web
page for more information on this. (May

- The first batch of
the new Grundig G4
and G6 SW portables have started to trickle
into USA dealers. The G4
was very lightly sold in China as the Degen
DE1122 (very few around). A larger
storage built in MP3 player/recorder over the
Degen DE1121 with 1 or 2 GB of built in memory
along with a SD / MM socket for more, but
elsewhere it says that up to 2 GB is with a
external card ? The biggest difference from the
elder Degen DE1121 or DE1102 is (it appears) that
there is no SSB mode. Full SW coverage, 1000
memories (no sync detection of course). FM ATS, 3
timers just like on the DE1121. Of course it
looks much like the Degen DE1102/Kaito KA1102.
But the major downer that I can see right off
other than the lack of SSB is, "where is the
tuning knob" ??
The G6 has aircraft band
included, a front mounted tuning "knob-wheel"
and is Dual Up-Conversion on SW. Both of these
models are made for eton-Grundig by Degen of
course.
  
The thrid new set from Grundig will
be the Satellit 750 and it now looks like a launch date of
perhaps late June or July ??? Of course Tecsun
making this model. Where is the sync detection ?
It covers the aircraft band just like the old 800
did. (May 02)

- "
The JRC NRD-545 HF
Receiver is history " : Universal Radio in
Ohio , USA and Grove Enterprises have both sold out of the JRC NRD-545.
This is the end of an era as no new JRC receiver model is in the
works as far as we know. Was a good 10 year run.
The AOR AR-7030 will be
gone in the weeks to come as well. If you desire
a brand new AR7030, better do it NOW
!! If you live in the USA, Universal Radio is the only dealer where
it can be purchased (Plus version) (Updated : Apr
28)
- Internal picture of
the Degen DE1121 (Kaito KA1121 )
"MP3 Unit" added on the " Dave's
Miscellaneous Stuff " page. It's
still the only "portable"
receiver on the market that features a built in
"off the air" MP3 audio recorder AND
includes SSB mode plus a tuning knob. The
Icom IC-R20 works less well overall on SW , has
less record quality and is in some weird format.
Don't forget we also have a great "Broadcast
Log" and a couple of "Recording Scratch
Sheets" available for download on this
page. Also a custom "Setting Log"
for the MFJ-1025 / MFJ-1026
noise cancelling device. Our thanks to KD9JK for
the photo. (Apr 20)
- "Another
Sony Product Bites The Dust" : The Sony
MDS-JE480 "Mini Disc - home deck"
recorder has been
discontinued (USA), and it
appears that dealers are already sold out. It's
been gone for years in Europe and elsewhere. So
Sony's last Mini Disc DECK has come to an end and no replacement is
planned that I know of. There is a very similar MDS-JE580 model that is sold in Japan only.
Looks identical to the MDS-JE480
but is in a silver case.
However it's not all doom and gloom for "Mini
Disc" decks. Tascam (Teac)
sells at least one quazi-professional model, the rack mountable
MD-350. Another "deck"
that comes to mind is the smaller Onkyo MD-133 that also includes the
"Hi-MD" format. Note: The MD-133 model
is a Japanese domestic product but can be
purchased via Minidisco in the
USA. However, these are not low cost
decks as the MDS-JE480 was. (Updated

- "Two
More Sony SW Receiver's Discontinued"
: I was looking at the pdf version of the
Spring/Summer 2008 "Amateur Electronic
Supply" catalog (scroll down on this page,
this section is 2.4 Meg's large) ,
and on page 130.....I see they have the Sony
ICF-SW35 and ICF-SW11
both marked as a "Closeout". These are
marked as "Discontinued by the Manufacture"
within the Sony price listings near the front end
of the actual printed catalog (not shown in the
above linked PDF version).
On the US "Sony Style"
webpage the ICF-SW7600GR
is the ONLY SW set still listed for sale now. I'm
actually surprised that the ICF-SW7600GR
has hung in there as long as it has. How much
longer will Sony be selling even this model in
the coming year is a very good question ? (Updated
: Mar 20)
- The AOR AR7030
to be discontinued soon (both versions). We seen
this posted on the AOR JAPAN web site
They are
indicating the AR7030 Plus as "Production
End" and the AR7030 as
"Sale End" ? We now have solid word that AOR
UK
has about 50 new samples left to be
manufactured (the very last
production run), and that will be
it (no more) ! Who knows how long those last new
samples will last in the marketplace ? A DSP
replacement is "quazi-planned" in the
next year or so ? Cross your fingers. Another
great long run with a fantasic HF receiver , but not without a
few "pot holes" in the road along the
way. (Updated : Mar 12)
- Universal
Radio in Ohio USA has the JRC
NRD-630 "on sale" for $ 7999.95.
Special order with a 3 to 4 week waiting time. 32
bit DSP based set. You
can download a brochure (PDF) here. (Feb 08)

- Alternative to the
now very old Realistic Minimus-7
speaker for HF receiver use? If you wish for a GOOD
external speaker for your SW/HF receiver, here is
one that deserves attention.
The
Source (which is Circuit City - InterTAN -
Canada , who bought out all of RadioShack stores
in Canada a few years ago) has a close "clone"
speaker. It is sold as the Centrios - 7,
part number : 4012000 for Black , 4012001 for Silver. This is 2-way speaker that
uses a 4-inch woofer and in a heavy die cast
metal cabinet (not plastic). I like using a 2-
way speaker for much improved audio articulation
(yes, even on a HF receiver with broadcast
stations).
The downside is that it appears to be only sold
in Canada by the "The Source" ? They
will NOT ship or export
outside Canada.
We have been very fortunate to be able to test
out a "Centrios - 7" , and the sound quality is
very good for this use to my ears. It takes
little audio power to drive properly too. I will
admit on a receiver with a hissy output (example:
Icom IC-R70), this is not the
one go with. However, a near perfect speaker for
use with the AOR AR7030's bass and treble controls
or even with the JRC NRD-545. 8 ohms impedance and is
made in China. Our thanks again to Dan Gillet. (Feb

Motorola
has now slurped up most of Vertex-Standard-Yaesu.
Will this be the start of the end of V-S-Y amateur
transceivers / receivers ?? CNN link for more
information. , also see this
"eham" link. However this makes the
news above makes one wonder what's up : "Motorola may
spin off or sell phone unit" (yahoo) , via Bloomberg. (Feb 02)
A price has now
been announced for the new Kneisner &
Doering KWZ-50 DSP receiver. At least
3620. euro's (ouch) not including the spectrum
display option. That is over the $ 5000. USD ball
park area just for the receiver alone.
See this link for more information and a picture
(drawing ?) of the set : http://kd-elektronik.com/kwz50_e/index.html (Jan 22)
A
"Black Box" DSP HF receiver from DRS
(the old Watkins Johnson folks). The model is the XK-3050.
Features
4 independently tuned channels. HF coverage is
marked between .5 and 30 Mhz. Modes : AM, FM, USB,
LSB and CW (no sync was indicated in the pre-production
brochure). 74 DSP IF bandwidth filters, ranging
from 56 hz to 32 Khz. Power is from a external 5
VDC @ 3 watts supply. SMA antenna connectors.
Multi screen spectrum scope , also wav. recording
selection on windows based GUI screen. Weight is
only 1.6 lbs. Uses SMA connectors. Optional
preselector. Requires USB 2.0 port on a 1.6 Ghz
or better host computer (windows 2K or XP). Price
and status are both unknown, but reports
are indicating between $ 5000. to $ 6000. ?? This
is all of the information that I have at this
time. It has been in the works since 2006. Our
thanks to Dan Gillet for this news. (Updated: Feb

Vertex-Standard-Yaesu
VX-3R review page has now had a major and
final rewrite. After using it for awhile, I have
now concluded that it is not as good overall vs.
the older VX-2R for my uses and desires (even
with the CTCSS/DCS decode bug fixed). I have
since gone back using my "new sample"
VX-2R full time and have already let the 3 go. Be
sure and read the totally
updated page for more information why I feel
this way. But the VX-3R is still way better over
the Icom IC-P7A to my eyes and ears. UPDATE :
My latest VX-2R sample made in 2007 has the
"power on" bug afterall. So this
gremlin must have been with the set until the end
? But at least the LCD display bug was fixed.
Working good other than this. (Sep 28)
T.K.
emailed me a picture of a prototype Icom
HF transceiver marked as the model IC-7200.
This was shown at the Tokyo Ham Fair 2007 behind
a plastic panel. I have no additional information.
(Aug 27)

News via a Japanese
blog, a very interesting DSP receiver
from China. As you can see it looks very much
like a WJ8711 / HF1000. This DS-400
receiver is made by "Haihua Electronics
Enterprise Corporation" in Guangzhou, China. T.K.
found out that the pricing appears to be at $ 11,000.
(USD). Of course we have to
throw in the usual question, "Does this
receiver actually exist on the planet",
or is it just vaporware ? A brochure in
Chinese here . This RAR brochure
is mixed with other products. Very few
specifications (it's in Chinese of course), and
any real detailed information or better pictures
is simply not available. I do not have additional
information on this (sorry). (Updated: Apr 12)
