Please email [email protected] if you wish to claim a new record, longer distance QSO not yet documented, or records for any other satellite/transponder not yet listed. Please note that if a satellite carries multiple transponders or supports multiple frequency bands, records on each transponder/band may be claimed, such as Mode A and B on AO-7 or Mode U/S, L/S, U/K, etc, on AO-40. This includes the ISS and records may be claimed for the packet digipeater and crossband repeater, but does not include different operating modes on the same transponder (such as CW or SSB on AO-7 Mode B).
