CHASERS

Ask the OTA bot who has chased your op and is still waiting on your QSL. Send it from the station running your op. The reply is the callsigns of every chaser who you have not confirmed yet. The chasers are sorted with those who have waiting longest first.

K7ABC-6OTACHASERS
OTAK7ABC-6W1XYZ-5 N0CALL-7 KJ4HQS-15

When nobody is waiting:

K7ABC-6OTACHASERS
OTAK7ABC-6No one is waiting on your QSL.

A chaser who has sent their chase message but whose position report has not arrived yet is not on the list. Once their beacon arrives, OTA relays their call to you as a DE message and they are eligible to appear in the CHASERS response until your QSL goes out.

A busy op can have more chasers waiting than one APRS message holds. In that scenario the answer comes as two numbered messages. If two messages cannot hold all the chasers the second one ends with the URL to the op’s page, where you can see all the chasers at once. The chasers dropped from the second message are the ones who have waited for the shortest time.

See Host an op for more about working a pileup.
