LA0FA — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Norway Most frequent locator attributed to this token: JO59

Receiver-side FT8 activity involving LA0FA, decoded by SO8OO in southeastern Poland. 1,889 FT8 messages attributed to this token as transmitter, on 160m, 80m, 60m, 40m, 20m, 10m, across 68 UTC dates in the available aggregate history. Observed between 2026-06-07 and 2026-10-05.

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 1,889 FT8 messages attributed to LA0FA as the transmitting token by decoded message structure across 68 UTC dates in the available aggregate history. The largest monitored-band total was 40 m (24%), followed by 80 m (21%) and 60 m (20%). Most decodes (58%) fell within the six-hour window 20:00-02:00 UTC. Most successfully decoded messages attributed to this token fell in SO8OO's strong S/N range (76%); the estimated median was -1.8 dB.

Observed FT8 message patterns

Attributed sample: 1,889 messages
Active dates: 68 UTC dates
Estimated median S/N: -1.8 dB
Estimated 10th-90th percentile: -14 to +10 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 143, moderate (-15 to -9 dB) 315, strong (≥ -8 dB) 1,431.

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.

Rolling 90-day UTC chart window. Counts follow decoded message structure: the first token for CQ, or the second token in a directed-looking message.

Most frequent locator attributed to LA0FA

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.

Attributed locator: JO59 · 983 decoded messages
SO8OO receiver locator: KN09VW
Locator-centre separation: 1,266 km (approx.)
Last such locator decoded: 2026-10-05 21:33 UTC

Other locator fields attributed to this token: JO48 (71).

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