F4SHP — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: France

Receiver-side FT8 activity involving F4SHP, decoded by SO8OO in southeastern Poland. 25 FT8 messages attributed to this token as transmitter, on 20m, 10m, across 6 UTC dates in the available aggregate history. Observed between 2026-06-08 and 2026-08-28.

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 25 FT8 messages attributed to F4SHP as the transmitting token by decoded message structure across 6 UTC dates in the available aggregate history. The largest monitored-band total was 10 m (64%), followed by 20 m (36%). Several six-hour UTC windows tied for the largest share (88%), so no unique busiest interval is claimed. Most successfully decoded messages attributed to this token fell in SO8OO's weak S/N range (60%); the estimated median was -18 dB.

Observed FT8 message patterns

Attributed sample: 25 messages
Active dates: 6 UTC dates
Estimated median S/N: -18 dB
Estimated 10th-90th percentile: -23 to -4 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 15, moderate (-15 to -9 dB) 5, strong (≥ -8 dB) 5.

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.
