[arm-allstar] Receive only node

This would be fine so long as no two nodes receive a signal from the same
transmitter. This would result in a phase shifted signal that would sound
like an echo. If you set it up for an HT (1-5 Watts) then someone comes
along with a 20 watt or so radio, it would be an issue. This is why the
voter system was established.

See https://allstarlink.org/voter.html

It is a bit more involved than your proposed solution.

Subject: [arm-allstar] Receive only node

Hi all,

I'm working on getting an allstar node connected to our local repeater 
and have been thinking about setting up some local receive only nodes in 
a couple of local hand held black spots. A good example is the local 
harbour where users can hear the repeater fine but just cant make it in 
on a small hand held radio.

The idea would be to have a small hand held radio programmed to receive 
on a simplex 70cm frequency, feed the audio into the RPi and have this 
connect to the local repeater. The user would just set an odd split in 
their radio so they can TX on the node RX freq and RX on the repeaters 
TX freq. The local node should not transmit at all.

Would this sort of set up be easy to do?
