[amsat-bb] Packet on AO-27

At the end of the AO-27 pass at about 2023 UTC today I heard a strong packet signal on the downlink. It lasted for about 30 seconds and wiped out the end of the pass for me. I think I've heard that before but can't remember if it was on AO-27. Is this just someone creating QRM or is the packet signal there for a reason?
