Working the ISS using APRS/Packet is different than working through normal APRS/Packet.
The following will help you get work APRS/Packet using the ISS. Note that at present the TNC is set to NOCALL, the default bootup call. Please read the articles before transmitting. As I find articles and hints, they will be added to this page. Many thanks to the AMSAT, SAREX and UI-View list users and maintainers for a lot of this information.

"NOCALL" will eventually be "R0ISS", R Zero ISS.

PLEASE DO NOT USE UNATTENDED BEACONS/PACKETS - TRANSMIT MANUALLY (articles will tell you why)
