EA5JKB — FT8 activity observed at SO8OO
Receiver-side FT8 activity involving EA5JKB, decoded by SO8OO in southeastern Poland. 51 FT8 messages attributed to this token as transmitter, on 80m, 60m, 40m, across 6 UTC dates in the available aggregate history. Observed between 2026-09-14 and 2026-09-19.
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.
SO8OO decoded 51 FT8 messages attributed to EA5JKB as the transmitting token by decoded message structure across 6 UTC dates in the available aggregate history. The largest monitored-band total was 40 m (41%), followed by 60 m (35%) and 80 m (24%). Several six-hour UTC windows tied for the largest share (98%), so no unique busiest interval is claimed. Most successfully decoded messages attributed to this token fell in SO8OO's moderate S/N range (61%); the estimated median was -14 dB.

WSJT-X defines S/N reports against a 2,500 Hz reference noise bandwidth. The ranges above are SO8OO receiver-side display categories, not official WSJT-X classes, transmitter-power measurements or estimates of how easy the station is to hear elsewhere. Statistics include only successful decodes on SO8OO's monitored FT8 channels; transmissions that were not decoded are absent.
