EW8MZ — FT8 activity observed at SO8OO

DXCC entity inferred from callsign: Belarus Most frequent locator attributed to this token: KO42

Receiver-side FT8 activity involving EW8MZ, decoded by SO8OO in southeastern Poland. 67 FT8 messages attributed to this token as transmitter, on 160m, 80m, 40m, across 3 UTC dates in the available aggregate history. Observed between 2026-07-05 and 2026-09-19.

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 67 FT8 messages attributed to EW8MZ as the transmitting token by decoded message structure across 3 UTC dates in the available aggregate history. The largest monitored-band total was 160 m (52%), followed by 80 m (45%) and 40 m (3%). Several six-hour UTC windows tied for the largest share (91%), so no unique busiest interval is claimed. Most successfully decoded messages attributed to this token fell in SO8OO's strong S/N range (94%); the estimated median was -3 dB.

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 2, moderate (-15 to -9 dB) 2, 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 EW8MZ

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: KO42 · 24 decoded messages
SO8OO receiver locator: KN09VW
Locator-centre separation: 577 km (approx.)
Last such locator decoded: 2026-09-19 01:39 UTC

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