Hello Tom,
Make sure you create correctly the "out/" directory where you are running the script and check user permissions to write there the "out.cf" file. Don't change the output filenames, as somewhere in the internals the GNUradio blocks in "channelyze.py" are expecting these filenames.
BR,
Pedro

Hi all
Trying to get frequency hopping on gnuradio 3.7 and
https://github.com/BogdanDIA/airprobe-hopping
The build goes fine but when I try to run ./capture_decode I get the
following.
./capture_decode_channelize2.sh

I am trying this with USRP1 and my clock frequency is changed to 52mhz.
Can someone please tell me what need to change.
