My code uses fftsink2 whereas you are using fftsink. I was a little
bit lazy when I posted the lines relating to fftsink2 since they were
kind of long. Here is the full line

self.rx_src_fft0 = fftsink2.fft_sink_c(panel,title="ChRXB-A",
y_per_div=25, ref_level=fftreflev, average=False, fft_size=fftsize_N,
sample_rate=rx_rate/sw_decim)

similarly for the other channel. make sure you have "import fftsink2"
at the top as well. Here is a link to the file that works for me
