I queried two of the foremost amateur radio reviewers about the new Airspy
HF+. Here are their responses:

Hi Larry,

Just a couple of comments. IP3 is a meaningless number for a direct
sampling radio. I also don't understand the meaning of "image rejection" as
applied to a DS SDR.

There must be quite a bit of preamp and/or ADC driver gain to push the noise
floor down to the levels quoted. What is the ADC overload value in dBm for
any preamp settings?

What is the phase noise at 10, 20 and 100 kHz on 20 meters? That is likely
more important than at 1 kHz offset where in reality if listening to a weak
CW signal next to a very strong CW signal, the adjacent signal's key clicks
will dominate before phase noise.

Is there an RMDR spec for the receiver at 2 and 20 kHz, as is now usually
quoted in any review in QST?
One would expect the RMDR value to be HF ham band independent.

When I was writing for Passport to Worldband Radio for its 25 years of its
existence as their laboratory, receivers as opposed to transceivers would
have been of prime importance. Today with a significant drop in shortwave
broadcasting, I don't think the shortwave market is a shadow of its former
self.

On the other hand, SDR dongles are being used for spectrum scope for
transceivers missing this feature, and for CW Skimmer and reverse beacon
reception.

At present with new product announced at the Dayton Hamvention, I am only
planning to test DS SDR transceivers this year. Examples: Icom IC-7610,
Flex 6600M, Apache ANAN 8000DLE, and a second and possibly a third sample of
the Elecraft KX2. I have the second KX2 here now in my possession as of
last evening.

Adam may have more time than I for testing receiver only products, as I am
still working part time with a sub set of my IT client base, at least for a
few more years.

Rob, Larry,

Just looked over the Airspy HF+ web page. Firstly, a look at the block
diagram tells me that this is a superhet receiver, with analogue mixers and
LO's for HF and the two upper bands feeding IF's into an ADC. Hence the
"image rejection" term is relevant. (As an aside, the non-native English
writing style of the website is a little weird.)

No RMDR value is stated, but the specified 100 MHz phase noise value does
not look too good when expressed as RMDR.

"Very low phase noise PLL (-110 dBc/Hz @ 1kHz separation @ 100 MHz)".
Assuming B = 500 Hz, this resolves to 83 dB RMDR - less than stellar by any
account.

The device appears to have a varactor-tuned tracking preselector. Due to
parametric effects in the varactors under strong-signal conditions, this can
be a horrendous IMD generator, as we saw with the early JRC receivers and
transceivers.

Rob, I agree completely with your comments regarding receivers vs.
transceivers and the uses to which dongles are put. For HF and 6m, I believe
that the Russian Colibri Nano is a much more interesting device than the
Airspy. It is a 14-bit direct-sampler. Here is my Nano test report:

http://www.ab4oj.com/sdr/sunsdr/nano_notes.pdf

I am more than willing to test serious contenders in the receiver world. For
example, Icom Canada will loan me an R-8600 for testing, probably next
month. I am no longer motivated to test any purely legacy architecture;
although I am retired and have more available time, I do have a life outside
my little 6.5m2 lab.

Airspy HF+ (Coming soon)
You are here: HomeAirspy HF+ (Coming soon) Description

The Software Defined Radio revolution brought great flexibility in VHF and
UHF reception. Today we offer the best wide band receivers which address
these needs. We also provide a high performance extension for weak-signal
wide band reception on HF - something other competing solutions in our price
segment fail to address efficiently.
Airspy HF+ is a paradigm shift in high performance HF radio design. It is a
joint effort between Airspy, Itead Studio and some famous chip maker to
build a state of the art SDR for HF and VHF bands.
Like most high-end HF receivers, the HF+ uses very high dynamic range ADC's
and front-ends. But unlike the current offerings in the market, it also
brings more frequency agility by using high performance passive mixers with
an excellent overtone rejection structure. No external band aid filters are
required like the lower end HF receivers, which makes it the ideal companion
for light portable high performance operation.
Both the architecture and level of integration achieved in this design allow
us to bring top performance reception at a very affordable price.

All the major SDR software is supported. Check the download page.

We concentrated state of the art DSP and networking techniques into our
SpyServer software to allow multiple users to stream high quality IQ data
from the same receiver at the same time. No compromises in the quality were
made like it is usually done in Web SDR interfaces. You get actual IQ data
you can process with your plugins and extract the last bit of information
out of it.

The server software is highly scalable and can run on computers as small as
the $7 Orange Pi Zero to top end 64bit servers with multiple cores/cpus,
passing by the popular Raspberry Pi series.

Airspy HF+ Cloud

Architecture

Airspy HF+ Architecture Diagram

HF Tuner

Airspy HF+ achieves excellent HF performance by mean of a low-loss band
filter, a high linearity LNA, a high linearity tunable RF filter, an
over-tone-rejection (OTR) mixer that rejects up to the 21st harmonic and an
IF filter.

The 6 dB-stepped AGC gain is fully controlled by the software running onto
the DSP which optimizes the gain distribution in real time for optimal
sensitivity and linearity. OTR is a key issue in wide band HF receivers
because of the large input signal bandwidth. The output of the IF-filter is
then digitalized by the IF ADC for further signal processing.

VHF Tuners

Excellent VHF performance is also achieved by using optimized signal paths
composed by band filters, high linearity LNAs with a stepped AGC and an
over-tone-rejection mixer and IF filters optimized for their respective
bands.

The amplifier gain is switchable in 3 dB-steps and is fully controlled by
the AGC processing running onto the DSP. The RF signal is converted to
baseband by a high linearity passive mixer with overtone-rejection
structure. The low-IF signal is then converted into the digital domain by
the IF ADC for further digital signal processing.

IF Digitalization

The IF digital to analog converter has a 4th order multi-bit topology; it
features very high dynamic range and linearity. The IF-ADC sampling
frequency is determined by a control algorithm running on the DSP. This
advanced technique changes the sampling frequency depending on the tuning
frequency with the goal of avoiding the disturbances generated by the
switching discrete-time sections of the IF-ADC.

Digital Down Converter

Once the IF signal is digitalized, the high sample rate I/Q stream is then
frequency translated and processed with cascaded CIC and FIR decimation
stages. After every stage, the sample rate is reduced and more the
resolution is increased. The final signal at the output has 18bit resolution
and the alias rejection performance is 108 dBc. The data is then scaled to
16bit and sent to the Micro-Controller for streaming over USB.

Use it over the network!

Connect as many SDR applications as needed to the HF+, over the Internet or
in your own local network with near zero latency thanks to the new SPY
Server software.

This setup basically brings all the flexibility of Web based SDRs while
still benefiting from the full power of desktop applications. The IQ data is
processed in the server with state of the art DSP and only the required
chunk of spectrum is sent over the network. What is sent is the actual IQ
signal, not compressed audio. This means you can use all your favorite
plugins to process the IF, eliminate noise and perform heavy lifting of the
signals as you are used to do with locally connected SDR's.

We have a tradition of building multi-tools, so we made sure the SPY Server
runs on 32/64bit Windows and Linux on Intel and ARM processors without any
compromises. Low cost Raspberry Pi 3 and Odroid boards are in the party.

"DX/weak stn capability insanely good. Weak stns very clear, not
clear on other SDRs. "
Paul,

If that really is so then what other SDRs?
Ones that suffer from wideband noise pickup?
How can that be? Does higher sampling depth make THAT much
difference? Sensitivity on ANY HF SDR on just about ANY antenna
should be adequate.

Hello,

I agree with Paul. I am using SDR Console V3 with my RSP2 on a daily basis since it is supported. I have not encountered any issue so far. Brilliant piece of software!
And IMHO: If authors would stick to modelling full featured transceivers/receivers evolution would come to a stand still...

Cheers,

Frans

Hi Vincent,

I'm using a 27" Dell like one that Simon has.  I drive it with a Gigabyte '1080.  There is also a NEC22" off to the left side.

BTW, a little while ago I finally realized why I couldn't run the the Dell @ 60 frames.  Doh!  I switched the interface from HDMI (bad) to Display Port (good).    Now, all is good in the world.

Not sure whom I'm addressing, as there's no sig line in your post...that said, what USB cable are you using with V3?  Per Simon's statement in the link below, "To ensure robust operation of the UHD.dll code you must use very high quality USB3 cables. Using USB3 extension cables seems to affect timing inside UHD.dll resulting in the software crashing with an access violation."

You'll find that and more info here:  http://sdr-radio.com/Radios/Ettus-Research

Per that same page, Simon's had the Ettus B200 running "very well" at his home QTH since September 2014.

Newer (rev 6) Ettus B200 (with AD9364) on SDR Console 2.3 or 3

michi@...
 

So, we're using an Ettus B200 at work where I really need to capture some signals. Ordered it with the impression that SDR-Radio 2.3 and 3 supported the device.


It seems I need to get it working under SDR-Radio 2.3, which only supports Firmware 3.7.1 on its UHD_SDR.dll included.


(The reason I can't use 3.0 is because I have one machine where immedately upon startup i get the "Please wait..." dialogue and it crashes to desktop - no amount of uninstall or reinstall or reset is fixing that. On another machine, SDR-Radio 3.0 operates extremely slowly, won't change the LO, and for some reason after you hit 'start', everything 'starts' but the 'start' button doesn't remain pressed, as in its not in a full 'start' state. These are other things I don't know what to do about here.)


In any case, SDR-Radio 2.3 works fine; but is constrained to Firmware 3.7.1 on the Ettus B200.  


Problem is this: I can go back to Firmware 3.7.1, but that only supports the 'older revision" of the Ettus B200, which had the AD9361 chip, not the AD9364 chip which is now included in the B200. (Only firmware 3.8.4 and above supports the newer hardware revision of the Ettus B200.)


Is there any way to obtain a newer UHD_SDR.DLL that supports firmware 3.8.4 and the AD9364 chip, or above?  


I know people are going to tell me to 'just go to gnu radio', but wow I don't want to do that :|


The only other alternative would be convincing the boss to return the ~$750 B200 and get a ~$1250 B210 which still has the AD9361 chip which SDR-Radio 2.3 supports.


The problems I'm having with 3.0 I really don't know what to do about. I can't find any references in the threads here to the immediate "Please wait..." problem (on one computer) or the weird sluggishness and controls not syncing with the state of the program (on another).   I chalked all of that up to the program being an alpha release, but it seems a lot of people use it as their daily driver, so I figure the issue must just be me. :|

Hello
I'm newbie with SDR Console
My equipment is :

FTdx5000 with Funcube on IF (9 000 000)

I also use LPB2 software to have 2 virtual ports :
The Hardware port is #7 and with LPB2 I create 2 virtual ports :
#8 use with Logger32
#9 use by Omnirig

I am running with Windows 10 / 64 bits French system

I use HDSDR ; CWSkimmer and CSJT-X thru Omnirig and that works fine

Actually I use HDSR Program but I saw a demonstration of SDR Console at Friedrichshafen and I would like to use it

1) The first question is about Omnirig

The first time : after I installed SDR Console that works fine

But If I close SDR Console and launch again it , that doesn't works I always have an error
Error creating Omnirig (see my screen copy) I don't know why ?

Omnirig is installated on  C:/Program Files (x86)/Afreet directory
SDR Console is installated on C:/Programmes/SDR-RADIO-Pro.com directory


2) The second question is about Frequency settings (External Radio Options)
25 juillet 2017 à 17:39
Hello

Does anyone use SDR Console with an FTdx5000 and a Funcube ??



 
I use elad fdm s2 with the if out of the ftdx5000. The if out option is not currently supported by sdr console.
It may be in the future.

Although I find V2 and V3 very impressive pieces of software, I find that they aren't modeled after a full featured transceiver/receiver.
I find that the RSP2 integration is quite buggy for the time being. HDSDR is quite friendly.
Different "Paul" here.....

While I too am a fan of HDSDR, I find SDR-Console V3 works just fine with RSP2 and on a laptop. In fact, I use V3 almost exclusively on my Thinkpad X1 Carbon laptop with either the touchpad or the Thinkpad Trackpoint. To tune to a specific frequency, tap on the waterfall. To tune up or down within the sampled bandwidth, scroll either way with whatever pointing device you are using. I don't see any material difference between tuning on V3 vs. HDSDR. In fact, I find V3 to be simpler and more intuitive than HDSDR because you don't have to worry about the "local oscillator".

Buggy integration in V3 with RSP2? I have found no bugs at all after updating to the current build. My only complaint is that where SDRUno stores the antenna selection with a stored memory channel, V3 does not. On the flip side, V3 stores the displayed bandwidth and SDRUno does not.

Re: favorites

Thanks Simon,
  I guess I need to wait memory banks are installed..  I am using favorites, but I found files I wanted to put in v3and I can not seem to import them.  Memory banks would probably sole my problem.  Thanks again.  This is really good software.
