Hello Jeff Thanks for replying >From what I learned in last two days in GNU Radio, it looks like gr-25 is an OOT module. gr-25 works with GR 3.9 and pybinds and I am using GR 3.8.1.0.
Also I want to implement G3RUH 2FSK AX25 using the core modules of GRC or programming new OOTs so that I can improve my learning curve. Any help would be appreciated from the community.
