TM25TFR — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: France

Receiver-side FT8 activity involving TM25TFR, decoded by SO8OO in southeastern Poland. 2,008 FT8 messages attributed to this token as transmitter, on 160m, 80m, 40m, 20m, 10m, across 9 UTC dates in the available aggregate history. Observed between 2026-07-14 and 2026-08-08.

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 2,008 FT8 messages attributed to TM25TFR as the transmitting token by decoded message structure across 9 UTC dates in the available aggregate history. The largest monitored-band total was 20 m (49%), followed by 160 m (45%) and 10 m (3%). The busiest six-hour window was 20:00-02:00 UTC, containing 42% of decodes. 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: 2,008 messages
Active dates: 9 UTC dates
Estimated median S/N: -15 dB
Estimated 10th-90th percentile: -20.9 to -7 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 879, moderate (-15 to -9 dB) 877, strong (≥ -8 dB) 252.

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.
