OL1TWR — 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 OL1TWR, decoded by SO8OO in southeastern Poland. 153 FT8 messages attributed to this token as transmitter, on 40m, across 3 UTC dates in the available aggregate history. Observed between 2026-07-02 and 2026-10-10.
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 153 FT8 messages attributed to OL1TWR as the transmitting token by decoded message structure across 3 UTC dates in the available aggregate history. The largest monitored-band total was 40 m (100%). Several six-hour UTC windows tied for the largest share (50%), so no unique busiest interval is claimed. Received S/N was mixed across SO8OO's weak, moderate and strong ranges; the estimated median was -15 dB.

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 70, moderate (-15 to -9 dB) 81, strong (≥ -8 dB) 2.
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.
