ES5MG — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Estonia Most frequent locator attributed to this token: KO38

Receiver-side FT8 activity involving ES5MG, decoded by SO8OO in southeastern Poland. 555 FT8 messages attributed to this token as transmitter, on 160m, 80m, 60m, 40m, 20m, across 5 UTC dates in the available aggregate history. Observed between 2026-08-27 and 2026-08-31.

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 555 FT8 messages attributed to ES5MG as the transmitting token by decoded message structure across 5 UTC dates in the available aggregate history. The largest monitored-band total was 160 m (31%), followed by 60 m (31%) and 80 m (23%). Most decodes (56%) fell within the six-hour window 17:00-23:00 UTC. Most successfully decoded messages attributed to this token fell in SO8OO's strong S/N range (62%); the estimated median was -6.5 dB.

Observed FT8 message patterns

Attributed sample: 555 messages
Active dates: 5 UTC dates
Estimated median S/N: -6.5 dB
Estimated 10th-90th percentile: -16 to +1 dB
Recurring-pattern threshold: Met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 57, moderate (-15 to -9 dB) 153, strong (≥ -8 dB) 345.

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 ES5MG

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: KO38 · 331 decoded messages
SO8OO receiver locator: KN09VW
Locator-centre separation: 1,010 km (approx.)
Last such locator decoded: 2026-08-31 06:10 UTC

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