3Z25POT — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Poland

Receiver-side FT8 activity involving 3Z25POT, decoded by SO8OO in southeastern Poland. 520 FT8 messages attributed to this token as transmitter, on 80m, 60m, 40m, across 5 UTC dates in the available aggregate history. Observed between 2026-09-01 and 2026-09-16.

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 520 FT8 messages attributed to 3Z25POT as the transmitting token by decoded message structure across 5 UTC dates in the available aggregate history. The largest monitored-band total was 40 m (59%), followed by 80 m (39%) and 60 m (3%). Several six-hour UTC windows tied for the largest share (51%), so no unique busiest interval is claimed. Most successfully decoded messages attributed to this token fell in SO8OO's strong S/N range (77%); the estimated median was -4.8 dB.

Observed FT8 message patterns

Attributed sample: 520 messages
Active dates: 5 UTC dates
Estimated median S/N: -4.8 dB
Estimated 10th-90th percentile: -11 to +10 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 12, moderate (-15 to -9 dB) 110, strong (≥ -8 dB) 398.

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.
