I/Q swapped? #160
Comments
Anyone ever figure this out? this thing is pretty useless with anything command line related without this being done. |
Some of my SDR apps do not offer I/Q swap. I have not looked at the code, busy on other projects and getting antennas up in the trees. |
Yea this has to be done in the firmware and I have no idea where to even begin with this thing. Ill have to take a look and see if its simple or above my head. |
Awesome glad to see this might fix stuff. I will try it out later |
Compiled the latest changes today and Cubic SDR on Windows is a bit weird with echoes on FM, but the Linux version is working well. SDR++ via SoapySDR choppy but using sdrpp server it works great. I find I need to manually run AGC gain down quite a bit to prevent overload. Listening to AM airport tower traffic I reduce it until l see the spectrum line go near flat and spurs mostly go away and stray signals just start to decrease relative amplitude. Choosing automatic AGC is too much gain. The AGC gain control on these apps are working smoothly for me. GQRX stumbles on both OSs here. |
I do not know if there is a standard for SoapySDR specs regarding I/Q assignment, multiple SDR apps need to invert I/Q to tune properly.
