Hi David,

did you run Zadig on the new computer?

Brgds, Edouard.


No input devices

David J Taylor
 

Just setting up on a new PC. Copied all the files from a working installation. Program starts, asks for VCRUNTIME. Installed both 32- and 64-bit versions.

Program now starts, but doesn't show the expected input devices. HackRF works with Spektrum, not seen in the SDRangel list. Pluto likewise. Feel I must be missing something obvious (again!).

Thanks,
David GM8ARV

Re: SDRAngel SSB Modulator #windows

Antonio Gutierrez
 

Hi Michael,

I am sorry you damaged the TX. In USB, the carrier changes amplitude it is true, but it is always there. In AM, FM and WFM the carrier should be there at the top. That changes when you change the TX value, yes. That is not the point. The question is to get the carrier suppressed as it was done in 435MHz. So the difference should be 40dB at least.
This spike makes LimeSDR to work delivering a continuus signal, so breaking it is easier if ou increase power and in addition you get a higher IMD.
My last test is with 50dB gain in High, I get 10db under the modulation inserting compresor. That is more acceptable.

I hope it can be solved by SW.
Thanks for answering

Kind regards
Antonio

I noticed that the Tx does funny things on the Lime until you use the NCO offset. So I think the DC peak does matter.

Re: FM and RDS data

David J Taylor
 

Broadcast FM demod is one of the few plugins that are left undocumented and this does not help.
There is a button with the typical RDS logo (it is small but hopefully recognizable, it looks like a Moebius band) that will switch on the RDS decoding.

Best regards,
Edouard.
======================================

Thanks, Edouard. I found the logo (although I didn't recognise it) and some fields are now being decoded such as type, but not the music name (BBC Radio3, classical music). So it's a start, but still some way short of SDR#.

Please understand that I am not complaining, just wanting to know what to expect.

Cheers,
David

Re: LimeSDR-Mini, sdrangel 4.3.0, ubuntu 18.04.1 64bit desktop, dell laptop i7-4800mq, intel-cpu opencl.

i provided the links to what i downloaded and installed.
i believe its just the latest official binary for your distro. windows, ubuntu/debian or macos.
of course i downloaded and installed ubuntu amd64 flavor
in my topic i listed sdrangel as 4.3.0

i do have alot of ppa's added for soapysdr, limesuite, gnuradio. etc...
i dont think there is a sdrangel ppa that i am aware of.


FM and RDS data

David J Taylor
 

Using an AirSpy HF+ I can get excellent FM radio reception. Using SDR# I see RDS data. Using SDR Angel I don't. Bandwidths etc. are similar. Am I missing something obvious? "Stereo" speakers are showing, and the SNR of the 19 kHz pilot is almost 40 dB.

Thanks,
David

Hi,

I am sorry but this is hardly understandable. Can you elaborate more on your context:
  - Where do you get the package from? A PPA (that I do not know of)? One of the releases in .deb format available in SDRangel Github repo releases? Do you compile from source?
  - Do you face an issue with the plugins? Missing? Not working as expected?

Best regards,
Edouard.

im pretty sure i have everything installed correctly as i can surf the spectrum when sdrangel is running pretty well.
what im wondering is after i select my limesdr in file source i then move down to the demodulators
usually i been playing with ATV and DATV
what i would like to know is are these my "Plugins" or do i need these plugins here?
https://github.com/f4exb/sdrangel/releases
SoapySDR support

SoapySDR support for both Rx and Tx. See:

what i mean is do i need to get those or are they already installed?
it appears i can Rx as i can browse through the spectrum just fine.

thanks

I noted that with the SDRPlay Pro2 Decimation doesnt seem to show on the screen, 
ie. the frequency limits don’t change as you increase decimation.
Im using the SDR to monitor the IF of my K3 @ 8.214 Mhz…so decimation 
is helpful in narrowing down the displayed bandwidth, I think (? ) am I doing this correctly?

But first we would have to properly identify what this odd behaviours are.
I will trust your eyes and ears, whenever you are confident enough, that your have a simple explanation to what is going on wrong.
The going wrong is usually not having only one step to it, it could have more than one trigger and they can also be totally unrelated.

Useful test is already there, that what you were doing by using the sdrangel at first place.
Secondly, when discrepancies occur, please make sure to observe everything that could potentially be a trigger for the specific problem.
Try not to observe more than one problem at the same time.... on the end,
you will have to play with app quite a few times and your brain will eventually link the good explanation for the odd behaviour.
Most of the time simple behaviours are often reproducible, but when things get's nasty they are voodoo and random :)

These findings played out by your time and your intelligence, will be ours invaluable report for specific HW sink/source driver.

I hope my writing have cleared out some way or a plan of finding tests for unpleasant behaviours,
and I am looking forward for your more accurate report of the behaviours you experienced/experimented!

Have got also new year's buldozer :)

I the next days I will try to debug this situation of yours and mine,

When I have new build, it will be posted, no worries :)

You can add RSP1a to the list of devices not to use below 2Msps [which is odd because it seems to work better below 2Msps in Gqrx].

I have the LimeSDR mini. it seems to works, but i experiment some odd behaviours. 
How can i help community with some useful tests ??

Re: Less Soapy than expected

Edouard Griffiths
 

Yes the link was missing from the Wiki this has been corrected. Generally a readme.md file can be found in each plugin source directory. The Red Pitaya "bug" is also mentioned and is due to the way the Red Pitaya SoapySDR module has been designed. If you don't need it just do not install or remove SoapySDR support for Red Pitaya.
