[App_rpt-users] NON- C-media Sound card and Pi GPIO

[William Franzin]

Would be great if there was a standard  virtual device that could be
connected to different physical radio interfaces.

/dev/radio0/ptt
/dev/radio0/cos
/dev/radio0/ctcss
& other signals

Then anyone building software could support /dev/radio and it would provide
audio in/out and various signals

Testing would be simplified too, could just cat /dev/radio0/cos to check
for signal or echo 1 > /dev/radio0/ptt.
