[arm-allstar] Radio-less node

[Al Beard]

Hi guys,

On a similar note, can I send the audio to the linux loopback device
and, on the other loopback side, feed this audio into a Codec2
process and transmit out on mode 700D? And, the other way round,
Rx of 700D feeds back it's audio into the node, when the node is not
busy?

BTW: My Pi 4B is awaiting.
