SA7LBO — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Sweden Most frequent locator attributed to this token: JO76

Receiver-side FT8 activity involving SA7LBO, decoded by SO8OO in southeastern Poland. 1 FT8 messages attributed to this token as transmitter, on 40m, across 1 UTC dates in the available aggregate history. Last observed 2026-06-22.

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 1 FT8 messages attributed to SA7LBO as the transmitting token by decoded message structure across 1 UTC dates in the available aggregate history. The available sample contains attributed decodes on 40 m (100%). The sample is too small to infer a recurring UTC-hour or received-S/N pattern.

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. The sample does not meet the threshold for a recurring time or signal-pattern claim (20 attributed messages, three UTC dates and five distinct 15-minute windows).

Most frequent locator attributed to SA7LBO

The map compares the centres and boundaries of the locator field attributed to this token by decoded message structure, 2° × 1° as a Maidenhead square, and SO8OO's six-character receiver square. The separation is not an exact antenna-to-antenna distance or a radio-path length.

A decoded locator can describe portable, remote or special-event operation and is not proof of a permanent station address or transmitter identity.

Observed FT8 exchanges

S/N cells show: decoded at SO8OO / report transmitted by the counterpart. An observed exchange is not a QSL or an official logbook confirmation.
