Data Recording Problems

Ken Alexander
 

Anybody here use the Data::Record functions a lot?

I have been making IQ recordings of 500 kHz portions of the mediumwave band with SDR Console and my SDRPlay RSPduo.  I use File Analyzer when I play them back so I can zoom in closely on each frequency to look for offset carriers and move around quickly through the files.

Recently, I noticed that when I play back my IQ recordings the display in Console is flipped left-to-right around the center frequency of the recording.  For example, my most recent recording is centered on 567 kHz.  However, a Navtex transmission on 518 kHz shows up on 616 kHz and a strong China Radio International station on 603 kHz shows up on 531 kHz!

Interestingly, File Analyzer shows all stations on their correct frequency and the stations are displayed correctly when listening live.  It happens only when listening to IQ recording, which is what I do most of the time, and it happens with WAV of RF64 files.

The same thing happens with my Airspy HF+ as well.  I'm using v3.0.7 build 1456, released on March 23rd.

Annotated screenshots attached.

Many thanks in advance.  I'd love it if I just need to click a button somewhere! 😜

Is there any way to manually adjust the receive bandwidth to something that is not listed in the pull down menu in version 3

Thanks

LimeSDR mini not Starting in SDR Console

Cor ZS6CR Rademeyer
 

I hope someone can help me, I am not too familiar with with how to do these setups.  My LImeSDR mini shows up in the Select Radio window, I can click on it but the Start button stays greyed out, and the bandwidth drop menu has nothing in it to select. (My SDRplay RSP2 works fine.)

Lime Suite and HDSDR receives fine with the mini.

Running on a fast win7 laptop.

Any suggestions what I should do to get it operating in SDR Radio?

Leif,

WASAPI, if coded correctly can give a latency of just 3ms. There is a 'secret' way to get even lower latency.

Hello Fernando,

It seems to me that ASIO is significantly better than WASAPI. Look at table 2 here:
http://sm5bsz.com/lir/rxdel/3-26out/rxout.htm
That is with support through Portaudio. It is of course possible that the support in Portaudio is better for ASIO than for WASAPI and that direct support could remove the difference.

Hi Simon,
The scheduler works perfectly. Thank you very much for that extremely useful tool and your efforts to offer the best in SDR programmes!

Another question. .. Is there any way to playback a recording and move faster back from a minute to another. There are the 5sec forward and back buttons, but in a several minutes recording?
Thanks again!

Yes.

 

V3 is settling down nicely, by the end of 2019 / start of 2020 I can start some interesting ham/swl projects.

Simon -

"But it beats working for a big company..." I agree, genius can better be shown in freedom and not in homogenization.

Look how popular your software is now - and very well written!

A bit more involved to get running the way I want, but that flexibility is just exactly what makes it so great.

Hi Jorge,

I am not Simon, but I think he won't mind that someone else answers this question.

Jorge, choose your recording, then click on Rec/Playback --> Navigator and the Navigator window opens on the lower part of your screen. Have a look on the screenshot, it should look similar than my example.


Best wishes,
Uwe.

Re: Connecting a CW-key

Alex DH2ID
 

As a CW key is hardware and SDR-Console is software, the only way to connect them is
a. by plugging the CW key plug into the SDR TRX hardware (if it has a CW socket) or
b. by using a program like fldigi, CW type/get or HRD 

It all depends on the SDR hardware. The LimeSDR can only use CW software.

I use SDR console only for SDR RX (SDR-IQ,ELAD FDM-S2, SDRPlay RSP-1a and HackRF).
My FlexRadio SDR TRX all have hardware CW sockets.

Re: Airspy HF+ question

John Keys
 

Sorry for your loss Paul,

 

As Simon said, “USB device has malfunctioned” is not good.  Most often, it means the device did not respond when the host began the standard USB enumeration sequence.  With the device connected, if Device Manager shows VID/PID values of 0, the device did not respond.  From my experience,  this behavior happens because a mechanical connection failed or an ugly electrical event occurred.  Since the radio doesn’t have an ‘A’ connector  hanging off its circuit board (like a thumb drive), I’d bet money on an electrical event.  

 

Any idea of what failed in the PC it was connected to? 

 

Regards,

--johnk

New one purchased already and working just fine.   Strange thing is the faulty one's still function so it's not completed dead but certainly beyond my repair skills.

Hi Joe, and thank you for your response.

Yes I'm a hobbyist music producer too and for that reason I use externals sound cards and equipment that use ASIO. But Simon told me that WASAPI has the same perfomance.

The real thing is that professionaly ASIO still being a reference in hardware and WASAPI has gaining her placement too, but anyway the audio profesional's developers still recomending ASIO and this was a really good option in SDR Console.

Asunto: Re: [SDR-Radio] ASIO compatibility??

You might be right. If you have ASIO devices on your computer with drivers installed, wrapper included, you will get a driver in your sound devices whether it be via direct sound or some other method MME.  Any input or output audio device configured for windows will show up in SDRC. Make sure you have these devices available in your computer first, if you can’t see the ASIO driver as playback or record, neither will SDRC. 

Like Paul said if the device don’t support the ASIO or the low latency it provides. Having the drivers installed to use your sound card is a moot point. Do you have at least a sound blaster?

My experience with ASIO goes back as far as the 90-2k when I was a hobby music producer using programs like Cubase. An ASIO component was installed to access ASIO compatible devices through windows sound.

ASIO really comes into its own with external devices like mixer desks for which the manufacturer writes a custom ASIO driver to minimise USB transfer latency and glitches.
If you mean ASIO4ALL, I think that's only a wrapper based on other Windows APIs (WASAPI???), designed to "look like" ASIO, and not having any real performance advantage.
OK, I'll sit down now and wait for the corrections :).

Re: Connecting a CW-key

Jeffrey Gray <jlgray.kr3ep@...>
 

It cannot be keyed manually as there is no place to plug in a key. HOWEVER, there is a way. It requires HRD, MultiPSK FLDigi or one of the other digimode programs. 
 You would have to use a keyboard to send CW just as you would PSK, FT8, RTTY etc.

CAT via Network ? #request

Hello,

Just want to know if possible to send CAT commands (freq, mode, bandwith, etc) to SDR-Console via UDT/TCP network.
Some kind of API available for that ? This would help programmers to develop kind of applications ....

Re: Offset for LimeSDR Mini - SOLVED

I did say I must be being stupid !

After much searching I got the answer - use the range option within view>options !



and as you can see - the range then goes to 10Ghz.

Knew it had to be something silly that I was doing - it might be worth updating the knowledge article on SDR-Comm as Its not obvious (until you know!) where and how to use the option!

Knew it had to be there - just needed to find it :)

As I say a great piece of software - donate and feed the dog :)
