F4NQX — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: France Most frequent locator attributed to this token: IN94

Receiver-side FT8 activity involving F4NQX, decoded by SO8OO in southeastern Poland. 59 FT8 messages attributed to this token as transmitter, on 40m, across 3 UTC dates in the available aggregate history. Observed between 2026-09-27 and 2026-10-03.

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 59 FT8 messages attributed to F4NQX as the transmitting token by decoded message structure across 3 UTC dates in the available aggregate history. The largest monitored-band total was 40 m (100%). Most decodes (83%) fell within the six-hour window 16:00-22:00 UTC. Received S/N was mixed across SO8OO's weak, moderate and strong ranges; the estimated median was -14 dB.

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 22, moderate (-15 to -9 dB) 24, strong (≥ -8 dB) 13.

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 F4NQX

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: IN94 · 13 decoded messages
SO8OO receiver locator: KN09VW
Locator-centre separation: 1,816 km (approx.)
Last such locator decoded: 2026-10-03 00:06 UTC

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