Check-ins (QNI)

When an amateur radio operator (a station) participates in a traffic net, the station needs to let the net operator know by checking in. These check-ins are tracked to understand how many stations are participating in traffic nets each month.

Station Activity Report (SAR)

ARRL Section leadership is interested in activity reports from stations participating in the national traffic system, and those stations holding the Official Relay Station (ORS) appointment regularly send Station Activity Reports to let us know about traffic activity. The SAR points are made up of these four categories:

Originated

(An off-the-air function) Any ARRL standard format message traffic prepared by you (the first party) for someone other than yourself (a third party), and filed at your amateur radio station for initial transmission over the air. Count one point. In other words, this is a radiogram which you created for another per-son using your station’s message number and call sign.

Note: A message that you create for yourself does not qualify as an Origination, but will be covered later under the SENT category.

Sent

(An on-the-air function) Any message traffic to be sent by your station to another amateur station (a second party), whether such a message is initially transmitted from your station as your Originated message for a third party, a message for your-self, or one that was received from another amateur station. Count one point.

Note: Messages sent by means of telephone, postal, E-mail, etc. do not count as Sent, however they may qualify for counting as Delivered.

Received

(An on-the-air function) Any ARRL standard format radiogram received over amateur radio by your station. This will include message traffic received, whether for yourself, for relay to another amateur station (the second party), or received for delivery to the message addressee (a third party). Count one point.

Note: Messages received by other means, such as telephone, postal, E-mail, MARS, in-person, etc., are not counted as Received, however they may cause you to Originate a message for later transmission.

Delivered

(An off-the-air function) Any message traffic that is delivered by you to the message addressee (a third party), provided that the message was received at your station by amateur radio and that the addressee is someone other than yourself. This delivery is done by telephone, postal, E-mail, in-person, etc. Count one point.

Note: A message sent by amateur radio to the final addressee at another amateur station is counted as a sent message, not as a delivered message.
