RD7X/QRP — reception at SO8OO

Signals decoded by SO8OO in southeastern Poland. FT8 and CW have separate histories; all times are UTC.

FT8 activity

DXCC entity inferred from callsign: European Russia

Receiver-side FT8 activity involving RD7X/QRP, decoded by SO8OO in southeastern Poland. 108 FT8 messages attributed to this token as transmitter, on 160m, 80m, 40m, across 6 UTC dates in the available aggregate history. Observed between 2026-09-30 and 2026-10-10.

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 108 FT8 messages attributed to RD7X/QRP as the transmitting token by decoded message structure across 6 UTC dates in the available aggregate history. The largest monitored-band total was 80 m (74%), followed by 40 m (17%) and 160 m (9%). Most decodes (83%) fell within the six-hour window 14:00-20:00 UTC. Received S/N was mixed across SO8OO's weak, moderate and strong ranges; the estimated median was -14 dB.

Observed FT8 message patterns

Active dates: 6 UTC dates
Estimated median S/N: -14 dB
Estimated 10th-90th percentile: -22 to +3 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 40, moderate (-15 to -9 dB) 40, strong (≥ -8 dB) 28.

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.
