APRS Voice Alert
Most APRS users set the APRS RX volume normally to zero to avoid hearing the incoming packet data sound all the time. A different way is possible by using the so called Voice Alert, where you set up your APRS RX with CTCSS 123 Hz subtone (Europe: 136,5 Hz) to be silent, but a short analoge voice call with this subtone is possible to get in contact and QSY immediately and not to occupy the APRS frequency. Kenwood radios like the TH-72 or the D700/710 do support this function with a dedicated menu point “Voice Alert” that you can activate in addition to the subtone to continously recieve all APRS pakets, too.
