Has anyone made a standalone CTCSS decoder that runs on the Raspberry pi or BBB? I want to decode multiple PL tones before feeding into my BBB node. IE I want DSP functionality even if I have to use two BBBs. I want one PL tone for repeat only while the other will allow connection to Allstar network. My radios do not have internal CTCSS. 73, Eric Guth 4Z1UG Node: 28422
