[aprssig] Standard PL Tone for 144.39

Sun Jun 3 00:44:49 UTC 2007

The voice alert is a system to let you know when you are in simplex range of another APRSer on the road and you can call them to make a voice contact if you wish.  Set your CTCSS or PL to 100 so only another APRSer transmitting the tone will open your squelch and allow you to hear the packet burp from their transmitter.  You send the 100hz tone with your packets and they can hear you if they run same settings.

No PL on a repeater.
Mobiles may run CTCSS 100 hz for what Bob calls "Voice Alert".  The idea is to make the burrrrrp audible when a mobile is in direct range.  Repeaters and fixed stations should never run a tone.  (As soon as something is always in range and always burrp-ing, people shut it off or turn down the volume.)
