Re: Python OOT module not showing up in GRC

Hi, I figured out the issue. As discussed in this previous thread, https://lists.gnu.org/archive/html/discuss-gnuradio/2015-08/msg00194.html

Indeed second Nyquist zone before decimation. My thought was 143.05 MHz -> transpose by 100 MHz using the DDC (NCO at 100 MHz considering the 200 MHz sampling rate) to reach 43.05, and after transposition, decimating to reach 8 MS/s (I do have Epcos B3607 SAW filters 140+/-3 MHz frontend to sel

I'd like to analyze a higher Nyquist zone with a X310 fitted with a BasicRX: trying to listen at 143.5 MHz (GRAVES), I can transpose by 100 MHz but am still far from the ~8 MS/s sampling I can use on the Gb Ethernet interface. Since the signal is only in the third Nyquist zone, I'd like to tell the
