Hi,
did you set the correct frequency? If it is outside the allowed range,
it is expected that the PLL cannot lock.
Best,

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:

What does this mean? How can solve this problem?
The dongle is working fine with SDRSharp or rtl_fm.
Thank you
