[aprssig] Voice Alert

[Joseph M. Durnal]

Misko,

Voice alert is when you send packets out on the APRS channel with a 100 HZ
CTCSS tone.  The idea is that you have the radio set to tone squelch and
you will hear packets that are sent with the tone.  Most of the APRS ready
radio models include it as a feature, although, with the right setup, it
can be done with a non APRS built in radio.  It is meant for attended
stations, of course.  The idea is that if you hear the packets, another
APRS station is in simplex range, you can call them with voice on the APRS
frequency and then QSY.  I think my trouble is that there have been too
many unattended stations running with the 100 HZ tone and more and more
that have turned down the volume all the way instead of just turning off
the tone.
