Except under emergency situations, which are the cases we are talking here.
Things like this really benefit from experience and practice though. If an emergency is the first time you try to really use your radio, it's probably not going all that well.
That is indeed true. Practicing is important. To remember: APRS is available on other frequencies and methods, one does not need a radio license to receive text messages.
APRS is friendly enough to permit sending messages using normal internet and receiving messages from friends while on the outdoors. However, all of this requires practice and know-how.
