Hello everyone, I am trying to make a cheap USB dongle working with
gnuradio and gnuradio-companion.
I just tried to use a source block and link to a waterfall sink.
This is the error that I got:
<<< Welcome to GNU Radio Companion 3.10.1.1 >>>
Block paths:
/usr/share/gnuradio/grc/blocks
Loading: "/home/lorenzo/Scaricati/fm_demod_mono.grc"
>>> Converting from XML

Executing: /usr/bin/python3 -u /home/lorenzo/Scaricati/top_block.py
gr-osmosdr 0.2.0.0 (0.2.0) gnuradio 3.10.0.0
built-in source types: file fcd rtl rtl_tcp uhd hackrf bladerf rfspace
airspy airspyhf soapy redpitaya freesrp
Using device #0 Realtek RTL2838UHIDIR SN: 00000001
Found Rafael Micro R820T tuner
[R82XX] PLL not locked!
[R82XX] PLL not locked!
>>> Done (return code -11)
What does this mean? How can solve this problem?
The dongle is working fine with SDRSharp or rtl_fm.
Thank you
