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?

Must run, Men's Shed..
