HB9IIH — FT8 activity observed at SO8OO
Receiver-side FT8 activity involving HB9IIH, decoded by SO8OO in southeastern Poland. 141 FT8 messages attributed to this token as transmitter, on 80m, 60m, 40m, 20m, across 7 UTC dates in the available aggregate history. Observed between 2026-06-16 and 2026-09-14.
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 141 FT8 messages attributed to HB9IIH as the transmitting token by decoded message structure across 7 UTC dates in the available aggregate history. The largest monitored-band total was 20 m (55%), followed by 40 m (27%) and 80 m (16%). The busiest six-hour window was 14:00-20:00 UTC, containing 49% of decodes. Most successfully decoded messages attributed to this token fell in SO8OO's strong S/N range (61%); the estimated median was -5 dB.

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 17, moderate (-15 to -9 dB) 38, strong (≥ -8 dB) 86.
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.

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 HB9IIH
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.
- Attributed locator
- JN36 · 60 decoded messages
- SO8OO receiver locator
