y Message receipt acknowledgment (ACK)
When a message is sent to a specific partner station, an ACK packet (receipt acknowledgment)
will be returned to acknowledge receipt of the message by the partner station. The transmission
process ends with an audio alarm to acknowledge receipt when an ACK packet is returned by
the partner station. When an ACK packet is not returned by the partner station for one minute,
the same message will be resent. The status will change to TX OUT if an ACK packet is not
returned by the partner station even after resending the message 5 times. The remaining
transmission count of the acknowledgment receipt will appear in the APRS MESSAGE LIST
screen as shown below. The remaining transmission count can also be checked by pressing
the DIAL knob to change to the transmit detail screen.
