IU2RKX — reception at SO8OO

Signals decoded by SO8OO in southeastern Poland. FT8 and CW have separate histories; all times are UTC.

FT8 activity

DXCC entity inferred from callsign: Italy Most frequent locator attributed to this token: JN45

Receiver-side FT8 activity involving IU2RKX, decoded by SO8OO in southeastern Poland. 115 FT8 messages attributed to this token as transmitter, on 80m, 60m, 40m, 20m, 10m, across 9 UTC dates in the available aggregate history. Observed between 2026-06-17 and 2026-10-22.

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 115 FT8 messages attributed to IU2RKX as the transmitting token by decoded message structure across 9 UTC dates in the available aggregate history. The largest monitored-band total was 40 m (62%), followed by 10 m (23%) and 60 m (13%). Several six-hour UTC windows tied for the largest share (77%), so no unique busiest interval is claimed. Received S/N was mixed across SO8OO's weak, moderate and strong ranges; the estimated median was -7 dB.

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 23, moderate (-15 to -9 dB) 29, strong (≥ -8 dB) 63.

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 IU2RKX

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.

A decoded locator can describe portable, remote or special-event operation and is not proof of a permanent station address or transmitter identity.
