JA7OBO — reception at SO8OO
Signals decoded by SO8OO in southeastern Poland. FT8 and CW have separate histories; all times are UTC.
FT8 activity
Receiver-side FT8 activity involving JA7OBO, decoded by SO8OO in southeastern Poland. 1 FT8 messages attributed to this token as transmitter, on 40m, across 1 UTC dates in the available aggregate history. Last observed 2026-09-21.
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 1 FT8 messages attributed to JA7OBO as the transmitting token by decoded message structure across 1 UTC dates in the available aggregate history. The available sample contains attributed decodes on 40 m (100%). The sample is too small to infer a recurring UTC-hour or received-S/N pattern.
Overview
Observed FT8 message patterns
- Attributed sample
- 1 messages
- Active dates
- 1 UTC dates
- S/N summary
- Too few decodes
- S/N percentile sample
- Too small
- Recurring-pattern threshold
- Not met
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. The sample does not meet the threshold for a recurring time or signal-pattern claim (20 attributed messages, three UTC dates and five distinct 15-minute windows).
