Good news. The Theseus Cores RFNoC polyphase filter bank channelizer is working.
The channel 0 timeouts, which were a vexing problem, seem to be gone thanks to hard work from EJ Kreinar and Phillip Vallance.
This particular part is vital for FDMA to TDM type payloads and groundsats. Having a fast, efficient, open source implementation that works in GNU Radio is a big step forward.
We are taking the entire setup with us to DEFCON. We are using a linux computer and a USRP. Experiments so far have been on the VHF ham bands and FM broadcast. Next step, move it up to microwave and demonstrate Phase 4 Ground channelization.
If you're at DEFCON, come by and see us in ham radio village! There's a license exam session, demonstrations, presentations, and lots of socializing.
More soon! -Michelle W5NYV
