Hi all, I need to bet back to basics:
At the command line, do I have the tools for a "parrot" repeater? Let's start: 1) a silence "raw" file dd if=/dev/zero of=blank count=1 2) generate a Codec2 mode 700D file c2enc 700D blank blank.c2 3) generate a RAW audio file freedv_tx 700D blank.c2 blank.raw --codectx Today this doesn't work, so did it ever?
