OH0/ES2TT — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Aland Islands

Receiver-side FT8 activity involving OH0/ES2TT, decoded by SO8OO in southeastern Poland. 162 FT8 messages attributed to this token as transmitter, on 60m, 40m, 20m, across 3 UTC dates in the available aggregate history. Observed between 2026-08-29 and 2026-08-31.

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 162 FT8 messages attributed to OH0/ES2TT as the transmitting token by decoded message structure across 3 UTC dates in the available aggregate history. The largest monitored-band total was 40 m (57%), followed by 20 m (40%) and 60 m (2%). Most decodes (66%) fell within the six-hour window 04:00-10:00 UTC. Most successfully decoded messages attributed to this token fell in SO8OO's strong S/N range (73%); the estimated median was -5 dB.

Active dates: 3 UTC dates
Estimated median S/N: -5 dB
Estimated 10th-90th percentile: -11 to +5 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 2, moderate (-15 to -9 dB) 42, strong (≥ -8 dB) 118.

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.
