Most APRS clients have the ability to send short station-to-station text messages. Messages may be passed through Igates, allowing long-distance contacts.

Short Text Messaging

An APRS message may be up to 67 characters long. Messages containing an identifier, an appended serial number, expect an acknowledgment from the address, and will be retransmitted until it is cancelled or times out.

General Bulletins

Bulletins are addressed to BLN followed by a single-digit identifier. Bulletins are retransmitted several times an hour for a few hours, and typically contain time sensitive information like weather warnings.

Announcements

Announcements are address to "**ANN**" followed by a single upper-case letter. Announcements are transmitted less frequently than bulletins and are usually not time critical.
