YU7AA — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Serbia

Receiver-side FT8 activity involving YU7AA, decoded by SO8OO in southeastern Poland. 64 indexed activity records, involving 20m, 10m. Heard between 2026-06-07 and 2026-08-20.

These are automated observations at the SO8OO receiver, not an official contact log. Times are UTC. Attribution follows decoded FT8 message structure: CQ uses the first token and directed-looking messages use the second. Free text that resembles a directed message can be attributed imperfectly. Summary S/N reflects propagation plus SO8OO receiver, antenna and local-noise conditions. Counts are not adjusted for monitoring outages; transmissions that were not decoded are absent. Inferred entity and location data may be inaccurate for portable, remote or special-event operation.
