Unfortunately, I wasn't able to find a nice generic way to make it easy to configure the PFBs. There is a good thread on it here, with some sample code: https:/

Unfortunately, I wasn't able to find a nice generic way to make it easy to configure the PFBs. There is a good thread on it here, with some sample code: https://github.com/robotastic/trunk-recorder/issues/76 https://github.com/robotastic/trunk-recorder/issues/76 If I can get a block of free time I am going to try and take another tilt at it. I did switch to FFT based filters and that helped a lot. CPU requirements are a lot less. Using RTLs with 2M sample size, instead of SDR more bandwidth also helps. It is a poor mans version of HW-based channelization.
