TA3NHM — FT8 activity observed at SO8OO
Receiver-side FT8 activity involving TA3NHM, decoded by SO8OO in southeastern Poland. 57 FT8 messages attributed to this token as transmitter, on 20m, across 3 UTC dates in the available aggregate history. Observed between 2026-08-02 and 2026-08-15.
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 57 FT8 messages attributed to TA3NHM 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 (100%). Most decodes (89%) fell within the six-hour window 07:00-13:00 UTC. Received S/N was mixed across SO8OO's weak, moderate and strong ranges; the estimated median was -15 dB.
Overview
Observed FT8 message patterns
- Attributed sample
- 57 messages

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 24, moderate (-15 to -9 dB) 30, 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.
Frequent counterpart tokens observed at SO8OO

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 TA3NHM
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
- KM38 · 25 decoded messages
- SO8OO receiver locator
- KN09VW
- Locator-centre separation
- 1,337 km (approx.)
- Last such locator decoded
- 2026-08-15 08:34 UTC
A decoded locator can describe portable, remote or special-event operation and is not proof of a permanent station address or transmitter identity.
