IQ9SZ — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Sicily Most frequent locator attributed to this token: JM78

Receiver-side FT8 activity involving IQ9SZ, decoded by SO8OO in southeastern Poland. 8 FT8 messages attributed to this token as transmitter, on 80m, 20m, across 3 UTC dates in the available aggregate history. Observed between 2026-07-16 and 2026-09-12.

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 8 FT8 messages attributed to IQ9SZ as the transmitting token by decoded message structure across 3 UTC dates in the available aggregate history. The largest monitored-band total was 20 m (75%), followed by 80 m (25%). In this small sample, the estimated median decoder S/N was -12 dB; no usual signal pattern is inferred.

Not met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 3, moderate (-15 to -9 dB) 2, strong (≥ -8 dB) 3.

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).

Most frequent locator attributed to IQ9SZ

The map compares the centres and boundaries of the locator field attributed to this token by decoded message structure, 2° × 1° as a Maidenhead square, and SO8OO's six-character receiver square. The separation is not an exact antenna-to-antenna distance or a radio-path length.

A decoded locator can describe portable, remote or special-event operation and is not proof of a permanent station address or transmitter identity.
