I installed GNU Radio on a different computer running ubuntu 16.04. Surprise!!! My test python file worked just fine. The reinstall that I did on 18.04 used the binary installatio. I did for the same binary install under 16.04 which installed 3.7.9.1 and 3.7.9.1 dev. The 18.04 installation is
gnuradio 3.7.11-10 amd64 GNU Radio Software Radio Toolkit
ignuradio-dev:a 3.7.11-10 amd64 GNU Software Defined Radio toolkit.
Cannot Access RTL Device
Re: Cannot Access RTL Device
Cleaned out gr-osmosdr and gnuradio. Did the reinstalls. Now GRC recognises the dongle. But I'm getting segmentation faults on the few examples I have.
Thanks for your responses.
