You gotta wonder, with the accelerating vacation of HF by
broadcasters, the stagnation in the development of DRM, the ongoing war
on the radio hobby by HOA's and local government, and the gathering
threat of BPL making some spectra difficult if not impossible to use,
just who is this rig targeting?


And for the kind of money asked for premium rigs by Ten-Tec, ICOM, AOR
and now JRC, what do they know that we don't? What's coming?


On the other hand, it's nice to know that someone is still interested
in building a receiver based on performance, rather than buzzword features.

Good question. I'm waiting to see the new offering by Kneisner + Doering.

Guy needs to chime in on this one.........I think the flex only does
that good on IP3 if used with the "approved" sound card ????

No big deal as I don't think that sound card is very expensive.

Those are REALLY good spec's for 1.8 mhz & above

I have heard several amateur radio op's using the SDR-1000 & they seem
to like them. Not sure if it is due to the receiver or the "HIFI" wide
band width SSB transmit. I know those op's running that bassy audio
think they sound good & do when they are 20 over but try to understand
what they are saying when they are in a pileup or just a little above
the noise level.

I for one just do not like using a receiver from a computer interface.
I have tried about all of the programs with several receivers & it
just takes the thrill factor of tuning a radio out for me. Many do like
software control & if you do.... have at it.

Personally, I have no interest in a 'radio' that requires a computer to operate.

But, here is a recent bit some might be interested in:

Winradio G313-E

I've been using the WiNRADiO 313E exclusively for DXing for the past
year, plus. I love the radio and cannot imagine ever returning to a
non-SDR receiver. Some of the main advantages of the WiNRADiO and its
Flex Radio SDR-1000 competitor are probably only applicable to people
DXing International MW and SW --- The Spectrum Scope, for instance,
allows you to focus in from 20 kHz wide (max) to 2 kHz wide at total
zoom-in. When you are working with close-together signals (say two or
three kHz apart, there is nothing like seeing the signals and then
graphically dragging the filter envelope and center-of-tuning to fit
them precisely between the QRM to achieve the maximum recoverable
audio.

The other thing that the Scope does is afford the user "situational
awareness" to a degree that is just unreachable without a scope.
Since you can see what you are trying to hear, in great detail, and
you can see the immediate surrounding signals, too, you immediately
know what adjustments need to be made to the receiver. It`s not that
you can't figure out what needs to be done --- bandwidth, mode, slot
filter, etc., in the traditional fashion --- its just so much easier
and faster to do it when you have graphical as well as the traditional
auditory input. This latter "situational awareness" aspect is
something that would benefit Domestic DXers, as well.

Another situational awareness attribute of the 313E that I really love
is the specific way that alpha-numeric notes can be displayed, after
they are associated with a particular memory and frequency. For some
years, there have been a few receivers on the market that allowed you
to store a title or some form of notes with each memory channel. That
way, WHEN YOU LOOKED AT THE MEMORY CHANNELS, there would be a title
like "Mem 1 BBC Evenings 5975 USB" or "Mem 2 R Australia 9580
AM." Well, the 313E does that, too, but in addition, it allows you
to associate a comment with each memory. Further and very importantly,
it displays that comment just beneath the Frequency Display on the
radio, WHENEVER the receiver is tuned (by any means) to that
frequency, whether you are in memory mode or not. So, when I have my
"Asian MW" memory file loaded, every time I tune past 891, the comment
appears just beneath the Frequency numbers on the radio WATCH FOR
THAILAND LATE. When I go to Grayland this weekend, when I pass 738,
the radio is going to remind me: RECORD PROBABLE JILIN PBS, etc., etc.
This ability should be of assistance to domestic DXers, too. Having
reminders come up every time you pass certain frequencies is a boon to
this 65 year-old DXer, let me tell you!

Two other special favorites and then I'll quit:

The synchronous detector is the best that I've ever used. In fact,
though I've owned most of the receivers with a sync detector, this is
the first that I've used as my primary DXing mode. Two reasons ---
first, by being synced on the carrier of choice, it actually
suppresses some sideband splatter and hash from adjacent signals
(wow!) further, even with signals out in the open, it seems to improve
signal-to-noise or intelligibility of weak signals. In my Okie terms,
"It hears better!"

Lastly, an attribute of most serious DSP receivers --- virtually
vertical sidewalls on the IF envelope. With any analog IF filters,
even the vaunted Collins mechanical filters, the actual window that
you are receiving the signal through is shaped like a truncated
equilateral triangle. Where your main DXing filter may be 2.7 kHz wide
at 3 dB down, it may be 15 or more wide at 30 dB down. The result of
that is that you use narrower filters that you really want to, to
conquer adjacent channel QRM --- AND since you have to use a wide
enough filter to let intelligible audio in, you also allow loud
adjacent splatter, etc. in "under the filter skirts."

With a total DSP package, from demodulation on down, the IF filtering,
of course, is done in the software. Hence, filter skirts that are
pretty-much VERTICAL. In my case, I can use say a 4 kHz wide virtual
filter rather than a 2.8 physical filter in the same conditions. Since
my 4 kHz filter lets in much more of the audio of my DX target (than
does a 2.8) I hear more intelligible audio. This would be true, all
things being equal, of any set that used virtual IF filters, not just
the Black Box receivers like the 313. Purists will argue that other
problems in the digital realm degrade this advantage, and to a degree,
they are likely correct. However, I can still keep my filters open
wider with this radio than with any of the excellent analog sets that
I've owned.

So, while the 313 black box won't be to everyone's taste, it lets me
hear more stations, better and easier than any set I've ever had
before. I may someday buy another main DXing set, but I'll guarantee
you that it will be a software-defined receiver.

P.S. I started MW DXing in the winter of 1953-54 and I love to use
classic tube communications gear. I especially love sitting and
staring at it while I listen and MOST OF ALL, I love tuning a really
well weighted, gear driven tuning knob. For years, I owned a mint 1942
SX-28A. Tuning that set was almost a sexual experience. I sold the SX-
28A to help me afford a totally rebuilt SP-600 --- turning that
counter-weighted knob and those beautiful brass gears WAS orgasmic. I
love DXing with those sets, and I was so sure that I'd miss a tuning
knob on the 313E that I invested in an outboard accessory tuning knob
(USB connected) that I used for about three evenings. I can just hear
more stuff more easily with this cold little box; and, in the final
analysis, my hobby is hearing DX and getting QSLs, not turning knobs,
counter-weighted or otherwise, JHB (John Bryant, WA, IRCA via DXLD 6-153)

No big deal as I don't think that sound card is very expensive.

The SDR has IMHO two problems. One is that it requires a PC to work and the
other is that you have to operate it via a PC.

If you like the ergonomics of a PC controled radio and have a PC next to
the radio then it's fine. I sit too long in front of a PC, when I use
a radio, I want a box with knobs, dials, switches, etc.

The Top 10 Reasons not to buy a FlexRadio SDR-1000

10. You have a knob, button and switch fetish.

9. The excitement of owning a radio that constantly gets better might cause
you to have a heart attack.

8. You don't need a radio that can double as a narrow band spectrum
analyzer with the best performance figures ever seen in this price class.

7. You don't need the kind of continuously variable, ring free, brick wall
filters, and noise reduction available with digital signal processing.

6. You have no desire for a needlepoint accurate near real time spectrum
display, that easily displays the weakest of signals among the strong.

5. You prefer a radio that requires costly accessories such as roofing
filters and preselectors, rather than buying a radio that is complete and
reaches its design specification at no extra cost.

4. You don't want a radio with the best sounding receiver and transmitter
available at any price.

3. You don't need the most responsive support network available anywhere.

2. You don't want to turn all your other radios into boat anchors.

And, the number 1 reason...

1. You can't handle any more fun in your life!

:-))
