hi！
I have some issues, I'd like to ask my predecessors.HAHA . Is the project to identify the modulation mode of the signal? I just don't know what WFM and DMR mean. I want to be a little silly...
In addition，Why do I run predict_scan.py programs,it wil stop when it predicts the first WFM ? and no more prediction of another signal..
Thank you very much for being able to answer this question. thank you !!
