ZA/KN7L — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Albania

Receiver-side FT8 activity involving ZA/KN7L, decoded by SO8OO in southeastern Poland. 1,232 FT8 messages attributed to this token as transmitter, on 160m, 80m, 40m, 20m, 10m, across 5 UTC dates in the available aggregate history. Observed between 2026-07-16 and 2026-07-20.

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 1,232 FT8 messages attributed to ZA/KN7L as the transmitting token by decoded message structure across 5 UTC dates in the available aggregate history. The largest monitored-band total was 20 m (33%), followed by 80 m (31%) and 40 m (30%). Most decodes (61%) fell within the six-hour window 20:00-02:00 UTC. Most successfully decoded messages attributed to this token fell in SO8OO's strong S/N range (65%); the estimated median was -7 dB.

Observed FT8 message patterns

Attributed sample: 1,232 messages
Active dates: 5 UTC dates
Estimated median S/N: -7 dB
Estimated 10th-90th percentile: -12 to +3.7 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 12, moderate (-15 to -9 dB) 415, strong (≥ -8 dB) 805.

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.
