RV3DBK — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: European Russia

Receiver-side FT8 activity involving RV3DBK, decoded by SO8OO in southeastern Poland. 43 FT8 messages attributed to this token as transmitter, on 10m, across 5 UTC dates in the available aggregate history. Observed between 2026-06-06 and 2026-06-13.

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 43 FT8 messages attributed to RV3DBK as the transmitting token by decoded message structure across 5 UTC dates in the available aggregate history. The largest monitored-band total was 10 m (100%). Most decodes (70%) fell within the six-hour window 06:00-12:00 UTC. Received S/N was mixed across SO8OO's weak, moderate and strong ranges; the estimated median was -14 dB.

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 15, moderate (-15 to -9 dB) 18, strong (≥ -8 dB) 10.

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.
