We just realized that blks2.standard_squelch does not work since GnuRadio
3.1.2. I installed 3.1.1 from source and it works fine, 3.1.2 and 3.1.3 it doesn't (basically everything passes through, independently of the threshold). We are using the usrp_nbfm_ptt.py (unchanged) from the gnuradio-examples. Anyone else notice this, or is it just our systems?
By the way, reading the code of standard_squelch.py, it seems to me that since
self.gate = gr.threshold_ff(0.3,0.43,0)
and
def set_threshold(self, threshold):
self.gate.set_hi(threshold)
squelch_range() should return (0.3, 1.0, 1.0/100), not (0.0, 1.0, 1.0/100). Am I wrong?
