YO/OE9RWH — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Romania

Receiver-side FT8 activity involving YO/OE9RWH, decoded by SO8OO in southeastern Poland. 47 FT8 messages attributed to this token as transmitter, on 80m, 60m, 40m, across 7 UTC dates in the available aggregate history. Observed between 2026-08-29 and 2026-09-08.

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 47 FT8 messages attributed to YO/OE9RWH as the transmitting token by decoded message structure across 7 UTC dates in the available aggregate history. The largest monitored-band total was 80 m (87%), followed by 60 m (9%) and 40 m (4%). Several six-hour UTC windows tied for the largest share (98%), so no unique busiest interval is claimed. Most successfully decoded messages attributed to this token fell in SO8OO's strong S/N range (81%); the estimated median was -5 dB.

Observed FT8 message patterns

Attributed sample: 47 messages
Active dates: 7 UTC dates
Estimated median S/N: -5 dB
Estimated 10th-90th percentile: -10 to +2 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 1, moderate (-15 to -9 dB) 8, strong (≥ -8 dB) 38.

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.
