GB13COL — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: England

Receiver-side FT8 activity involving GB13COL, decoded by SO8OO in southeastern Poland. 1,701 FT8 messages attributed to this token as transmitter, on 80m, 40m, 20m, across 8 UTC dates in the available aggregate history. Observed between 2026-07-01 and 2026-07-08.

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 1,701 FT8 messages attributed to GB13COL as the transmitting token by decoded message structure across 8 UTC dates in the available aggregate history. The largest monitored-band total was 40 m (54%), followed by 20 m (43%) and 80 m (3%). Most decodes (64%) fell within the six-hour window 20:00-02:00 UTC. Received S/N was mixed across SO8OO's weak, moderate and strong ranges; the estimated median was -15 dB.

Observed FT8 message patterns

Attributed sample: 1,701 messages
Active dates: 8 UTC dates
Estimated median S/N: -15 dB
Estimated 10th-90th percentile: -20.3 to -5 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 821, moderate (-15 to -9 dB) 543, strong (≥ -8 dB) 337.

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.
