SV9/OM1ARH — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Crete

Receiver-side FT8 activity involving SV9/OM1ARH, decoded by SO8OO in southeastern Poland. 51 FT8 messages attributed to this token as transmitter, on 60m, 40m, across 3 UTC dates in the available aggregate history. Observed between 2026-09-27 and 2026-09-29.

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 51 FT8 messages attributed to SV9/OM1ARH 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 (65%), followed by 60 m (35%). Several six-hour UTC windows tied for the largest share (100%), so no unique busiest interval is claimed. Received S/N was mixed across SO8OO's weak, moderate and strong ranges; the estimated median was -9 dB.

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 12, moderate (-15 to -9 dB) 18, strong (≥ -8 dB) 21.

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.

Observed FT8 exchanges

S/N cells show: decoded at SO8OO / report transmitted by the counterpart. An observed exchange is not a QSL or an official logbook confirmation.
