R2SDF — FT8 activity observed at SO8OO
Receiver-side FT8 activity involving R2SDF, decoded by SO8OO in southeastern Poland. 18 indexed activity records, involving 20m, 10m. Heard between 2026-07-08 and 2026-08-21.
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.
