IQ9SZ/2 — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Sicily

Receiver-side FT8 activity involving IQ9SZ/2, decoded by SO8OO in southeastern Poland. 2,602 FT8 messages attributed to this token as transmitter, on 80m, 40m, across 6 UTC dates in the available aggregate history. Observed between 2026-10-01 and 2026-10-06.

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 2,602 FT8 messages attributed to IQ9SZ/2 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 (67%), followed by 40 m (33%). Most decodes (67%) 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 (85%); the estimated median was -1 dB.

Observed FT8 message patterns

Attributed sample: 2,602 messages
Active dates: 6 UTC dates
Estimated median S/N: -1 dB
Estimated 10th-90th percentile: -10.2 to +5 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 85, moderate (-15 to -9 dB) 314, strong (≥ -8 dB) 2,203.

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.
