9A3AUH — FT8 activity observed at SO8OO
Receiver-side FT8 activity involving 9A3AUH, decoded by SO8OO in southeastern Poland. 14,102 FT8 messages attributed to this token as transmitter, on 160m, 80m, 40m, 20m, 10m, across 121 UTC dates in the available aggregate history. Observed between 2026-06-06 and 2026-10-05.
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 14,102 FT8 messages attributed to 9A3AUH as the transmitting token by decoded message structure across 121 UTC dates in the available aggregate history. The largest monitored-band total was 40 m (45%), followed by 80 m (41%) and 20 m (13%). Most decodes (57%) 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 (81%); the estimated median was 0 dB.

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 538, moderate (-15 to -9 dB) 2,137, strong (≥ -8 dB) 11,427.
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.

Attributed messages by UTC hour
Rolling 90-day UTC chart window. Counts follow decoded message structure: the first token for CQ, or the second token in a directed-looking message.
Most frequent locator attributed to 9A3AUH
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.
