[arm-allstar] Two nodes, 1 URI

[(KP4TR)Ramon Gonzalez]

Use an events stanza and use the "RPT_TXKEYED" to run a function or 
command to executes a cop command to turn GPIO on and off.

This page details how to use events subsystem:
http://ohnosec.org/drupal/node/176

The cop command for GPIO4 would be something like:
90=cop,62,GPIO4=0 ; Turn off GPIO 4
91=cop,62,GPIO4=1 ; Turn on GPIO 4

and a "rpt fun 1999 *91" would turn GPIO4 on and *90 turns it off.

And use the audio from the left or right channel.

Or easier yet..you can just share PTT and audio with your primary node 
to the second transmitter.
