R2BIO — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: European Russia Most frequent locator attributed to this token: KO85

Receiver-side FT8 activity involving R2BIO, decoded by SO8OO in southeastern Poland. 104 FT8 messages attributed to this token as transmitter, on 80m, 40m, 20m, across 7 UTC dates in the available aggregate history. Observed between 2026-06-06 and 2026-09-06.

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 104 FT8 messages attributed to R2BIO as the transmitting token by decoded message structure across 7 UTC dates in the available aggregate history. The largest monitored-band total was 80 m (52%), followed by 40 m (40%) and 20 m (8%). Most decodes (84%) fell within the six-hour window 15:00-21:00 UTC. Received S/N was mixed across SO8OO's weak, moderate and strong ranges; the estimated median was -13 dB.

Active dates: 7 UTC dates
Estimated median S/N: -13 dB
Estimated 10th-90th percentile: -22 to -5 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 44, moderate (-15 to -9 dB) 35, strong (≥ -8 dB) 25.

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 R2BIO

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: KO85 · 32 decoded messages
SO8OO receiver locator: KN09VW
Locator-centre separation: 1,193 km (approx.)
Last such locator decoded: 2026-08-21 20:39 UTC

Other locator fields attributed to this token: LN28 (13).

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