I’m going through some of the GNU Radio tutorials and I noticed that the
frequency axis for the QT GUI frequency sink is incorrect for real
signals (e.g., sample rate of 10k shows -2.5k to 2.5k). I found a bug
report (#541) from last year with the issue resolved in 3.7.0, but I’m
working with version 22.214.171.124. I didn’t notice any other bug reports
regarding this issue.
Note: The frequency plot in QT GUI sink is scaled correctly. Also,
the sampling rate while the flow graph is running corrects the scale.
