IZ6RDB


APRS On Demand

Through this innovative service it is possible to obtain on demand some of the information which is normally available through bulletins and announcements or that is not available at all otherwise. To obtain such information it is necessary to send an APRS message to the system with the information required and the system will then send back the appropriate information, if available.

This service is available locally (QTH JN63SO45NW) on the 144.950 MHz frequency at 1200 baud as well as on the global APRS network. The system transmits the eventual reply only once and does not attempt any message retransmission.
