N3UP — reception at SO8OO

Signals decoded by SO8OO in southeastern Poland. FT8 and CW have separate histories; all times are UTC.

FT8 activity

DXCC entity inferred from callsign: United States

Receiver-side FT8 activity involving N3UP, decoded by SO8OO in southeastern Poland. 4 FT8 messages attributed to this token as transmitter, on 20m, across 2 UTC dates in the available aggregate history. Observed between 2026-06-09 and 2026-08-21.

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 4 FT8 messages attributed to N3UP as the transmitting token by decoded message structure across 2 UTC dates in the available aggregate history. The available sample contains attributed decodes on 20 m (100%). The sample is too small to infer a recurring UTC-hour or received-S/N pattern.

Observed FT8 message patterns

Attributed sample: 4 messages
Active dates: 2 UTC dates
S/N summary: Too few decodes
S/N percentile sample: Too small
Recurring-pattern threshold: Not met

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).
