LA3TMA — reception at SO8OO
Signals decoded by SO8OO in southeastern Poland. FT8 and CW have separate histories; all times are UTC.
FT8 activity
Receiver-side FT8 activity involving LA3TMA, decoded by SO8OO in southeastern Poland. 181 FT8 messages attributed to this token as transmitter, on 80m, 40m, 20m, across 9 UTC dates in the available aggregate history. Observed between 2026-06-27 and 2026-10-31.
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 181 FT8 messages attributed to LA3TMA as the transmitting token by decoded message structure across 9 UTC dates in the available aggregate history. The largest monitored-band total was 20 m (56%), followed by 40 m (37%) and 80 m (7%). Most decodes (55%) fell within the six-hour window 18:00-00:00 UTC. Received S/N was mixed across SO8OO's weak, moderate and strong ranges; the estimated median was -11 dB.

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 37, moderate (-15 to -9 dB) 68, strong (≥ -8 dB) 76.
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
Tokens most often paired with LA3TMA in decoded directed-looking exchanges:
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 LA3TMA
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
- JP53 · 87 decoded messages
- SO8OO receiver locator
- KN09VW
- Locator-centre separation
- 1,640 km (approx.)
- Last such locator decoded
- 2026-10-31 23:14 UTC
A decoded locator can describe portable, remote or special-event operation and is not proof of a permanent station address or transmitter identity.
