Enable SDRPlay in Windows version #371
Comments
|
SDRPlay has unfortunately no native support. You can use it via the GNU Radio backend, by entering the directory GNU Radio was installed to at the bottom of the dialog. |
|
I tried to, but which directory do you choose? it seems like there needs to be some sort of OK button once the directory is picked, i have tried. But what ever i choose doesn't seem to stick. |
|
It should be the one where GNU Radios The supported way is to use the official GNU Radio installer from here. |
|
Just had a look at the source. There should be a directory |
|
Unfortunately it seems that there is no gr-python27 directory with pothossdr :-( C:. C:\Program Files\PothosSDR> |
|
Seems like this woll not work then. Is there a python.exe somewhere in the Pothos Install dir? If so, I could maybe add support for it. Is it an option for you to install GNU Radio to get the backend working? |
|
What you could also try is to define the path to the python 2 Interpreter (assuming you have one installed). I could imagine, that PothosSDR modifies the PYTHONPATH so it may be enough to just configure a Python 2 interpreter. |
|
Unfortunately no python.exe within C:\Program Files\PothosSDR My python directory is C:\Python27 |
|
PYTHONPATH=C:\Program Files\PothosSDR\lib\python2.7\site-packages |
|
It may work if you choose the radio button "Python2 interpreter" in the URH dialog from your screenshot and enter |
|
Tried that too, but the settings does not stay. Its like there needs to be an OK button when the directory is chosen if that makes sense.
|
|
As soon as you close the dialog box and get back in it defaults back to. |
|
This setting should stay if it works. If there is an error it defaults back to the empty value. You can check if your Python2 interpreter has GNU Radio support with this command: |
|
No Go. C:\Python27>python.exe -c 'import gnuradio' C:\Python27> |
|
Looks like the Windows CMD behaves a bit weird. If you are in that directory you can also simply enter and see if it works. If that is so, you can try to enter |
|
C:\Python27>python.exe
|
|
Is it working when you press enter? |
|
Yep, it accepts it when i enter the full filename. |
|
But still cant enable SDRPlay :-(
|
|
Was the |
|
No, it just came up blank.
|
|
This is actually a good sign! I have a suspicion what is going wrong here. Could you try entering with double quotes instead of single quotes like before and see if this runs without error? |
|
Runs without error. C:\Python27>python.exe -c "import gnuradio" C:\Python27> |
|
Thanks for your help, this is actually a Windows Bug in URH then because the Windows CMD, unlike a linux shell, does not work with single quotes in this case. I will fix this ASAP. |
|
Thanks Jopohl, Your work is truly appreciated. |
|
Could you share your top_block.py from your GNU Radio example ? |
|
uplpad sdrplay api , try to build add a native support. Thanks jopohl |
|
This is my gnuradio top_block.py |
|
Does it help if you change to Sorry for the long shots, but the SDRplay support was actually added by the community, so I can not verify my ideas because I do not possess an SDRPlay device. This would also make it very hard to develop a native interface. |
|
Change this" sdrplay=0" There is no use for anything，In the same way as the above |
|
Pothos sdr uses soapy device sdrplay Soapy imitates UHD devices，I can use USRP as an input So it's still building native support.
|
|
Can you provide us with some test devices or make a PR with native support? |
|
I'm sorry that my English is poor. Thank you very much！ I'm here at one o'clock in the morning, and I go to bed first |
|
Sure get some sleep mate. 👍 |
|
Im getting.
|
|
This seems to be an issue with the python2 interpreter. Does it work when you run this in terminal: Note the slight difference to the test we did above. |
|
It just returns a blank new line. |
|
What happens if you call: from command line? |
|
C:>cd Python27 C:\Python27>C:\Python27\python.exe "C:\Program Files\Universal Radio Hacker\sdrplay_recv.py" C:\Python27> |
|
Alright, this is the same error as in the application. Please add Futhermore, please share the output of |
|
C:\Python27>C:\Python27\python.exe "C:\Program Files\Universal Radio Hacker\sdrplay_recv.py" C:\Python27> C:\Python27> |

I just noticed, that the line numbers in your #!/usr/bin/env python2

What does give you? |

Seems like you have no zeromq installed for you python2 interpreter. You could try this: |

|
This may be an issue with Pothos by the looks of it, so don't worry too much about it if it cant be done.. I always have hackrf to capture with. :-) |
|
Looks also like a PothosSDR error for me, maybe Pothos is not supposed to be used in this way. You still have the option to install the official GNU Radio for Windows, which is better supported. If you do so, you need to configure the GNU Radio install dir in URH options. Unfortunately, we do not have the budget at the moment to afford a SDRPlay. I would add native support otherwise. |
|
Thanks Johannes for trying, ill try to reach out to the SDRPlay team and see what they can arrange, do you have an email address i could send them to contact you? |
|
Sure, just use my GMail address: Johannes.Pohl90@gmail.com |
|
No.. Thank you.. |
I'm unable to enable SDRPlay in windows version .msi
Not sure if it requires a dll file like other sdr's in the C:\Program Files\Universal Radio Hacker directory
Also i have the pothossdr suite installed and am able to use gqrx in windows with the SDRPlay, not sure if that makes a difference or not.
