SV8/F2VX — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Greece

Receiver-side FT8 activity involving SV8/F2VX, decoded by SO8OO in southeastern Poland. 852 FT8 messages attributed to this token as transmitter, on 80m, 60m, 40m, across 9 UTC dates in the available aggregate history. Observed between 2026-09-07 and 2026-09-15.

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 852 FT8 messages attributed to SV8/F2VX as the transmitting token by decoded message structure across 9 UTC dates in the available aggregate history. The largest monitored-band total was 60 m (41%), followed by 40 m (35%) and 80 m (24%). Most decodes (59%) fell within the six-hour window 18:00-00:00 UTC. Most successfully decoded messages attributed to this token fell in SO8OO's strong S/N range (73%); the estimated median was -3 dB.

Observed FT8 message patterns

Attributed sample: 852 messages
Active dates: 9 UTC dates
Estimated median S/N: -3 dB
Estimated 10th-90th percentile: -16 to +4 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 98, moderate (-15 to -9 dB) 135, strong (≥ -8 dB) 619.

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.
