Hi Chris, Thanks for your reply.
After countless hours of messing around, I partially have SDRPlay supported on a Raspberry PI 4 with gnuradio 3.8.2 Within gnuradio and osmosdr source blocks, I have SDRPlay data streaming, but I’ve not been able to turn the bias-tee on or make any sense of the gain settings. With gr-soapy source I’ve got trouble getting the stream of data to flow. with SoapySDRUtil —find I do find the device with reasonable values ###################################################### ## Soapy SDR -- the SDR abstraction library ## ###################################################### Found device 0 driver = sdrplay label = SDRplay Dev0 RSP1A 190316E696 serial = 190316E696 So, my question is: Do you (or anyone) have examples of the values to put in either of the source blocks to control the bias-tee gains and notch filters? Thanks again! Best regards Glen Again this was working perfectly in gnuradio 3.7.13 but is huge headache in later version. > On Nov 20, 2021, at 7:54 AM, Chris Vine <vine35792...@gmail.com> wrote: > > On Fri, 19 Nov 2021 10:04:06 -0500 > Glen Langston <glen.i.langs...@gmail.com> wrote: >> Hello Chris, >> >> I’ve seen your emails concerning SDRPlay and gnuradio 3.8 and 3.9 >> >> So far, after countless hours, I’ve yet to get SDRPlay working on a >> raspberry pi with gnuradio 3.8. >> >> My code works fine with gnuradio 3.7, but all the documentation for >> 3.8 seems to be out of date as everything was broken in the move to 3.9. >> >> Do you happen to have a Raspberry PI OS complete image that works >> with gnuradio 3.8 and SDRPlay? >> >> If so would you consider posting a copy of the entire OS? >> >> Thanks > > Hi Glen, > > I am afraid I don't have a raspberry pi so I can't help you with that. > I am now using gnuradio-3.9, but I had a RSP1A working well on x86_64 > hardware with gnuradio-3.8 with the following: > > * gnuradio-3.8.2.0 > > * soapy-sdr (repo https://github.com/pothosware/SoapySDR) master branch > as at the commit of 2020-07-13 > > * gr-soapy (repo https://gitlab.com/librespacefoundation/gr-soapy) > master branch as at the commit of 2021-02-16 > > * sdrplay-2.13.1 > > * soapy-sdrplay (repo https://github.com/pothosware/SoapySDRPlay2) > master branch as at the commit of 2020-06-29 > > As an alternative to the last two I have also used: > > * sdrplay-3.7.1 > > * soapy-sdrplay (repo https://github.com/pothosware/SoapySDRPlay3), > master branch as at commit of 2021-01-12 > > gr-osmosdr does not work correctly with gnuradio-3.8 with the RSP1A (nor > very well with gnuradio-3.7 either).
