TNX — FT8 activity observed at SO8OO

Receiver-side FT8 activity involving TNX, decoded by SO8OO in southeastern Poland. 204 FT8 messages attributed to this token as transmitter, on 160m, 80m, 60m, 40m, 20m, 10m, across 81 UTC dates in the available aggregate history. Observed between 2026-06-06 and 2026-09-20.

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 204 FT8 messages attributed to TNX as the transmitting token by decoded message structure across 81 UTC dates in the available aggregate history. The largest monitored-band total was 40 m (37%), followed by 20 m (26%) and 80 m (22%). The busiest six-hour window was 16:00-22:00 UTC, containing 41% of decodes. Received S/N was mixed across SO8OO's weak, moderate and strong ranges; the estimated median was -7 dB.

Observed FT8 message patterns

Attributed sample: 204 messages
Active dates: 81 UTC dates
Estimated median S/N: -7 dB
Estimated 10th-90th percentile: -19 to +3 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 35, moderate (-15 to -9 dB) 52, strong (≥ -8 dB) 117.

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.
