HB9MVV — 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: Switzerland Most frequent locator attributed to this token: JN47

Receiver-side FT8 activity involving HB9MVV, decoded by SO8OO in southeastern Poland. 4 FT8 messages attributed to this token as transmitter, on 40m, 20m, 10m, across 3 UTC dates in the available aggregate history. Observed between 2026-06-11 and 2026-11-03.

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 4 FT8 messages attributed to HB9MVV as the transmitting token by decoded message structure across 3 UTC dates in the available aggregate history. The available sample contains attributed decodes on 40 m (50%), 20 m (25%), and 10 m (25%). The sample is too small to infer a recurring UTC-hour or received-S/N pattern.

Observed FT8 message patterns

Attributed sample: 4 messages
Active dates: 3 UTC dates
S/N summary: Too few decodes
S/N percentile sample: Too small
Recurring-pattern threshold: Not met

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. The sample does not meet the threshold for a recurring time or signal-pattern claim (20 attributed messages, three UTC dates and five distinct 15-minute windows).

Most frequent locator attributed to HB9MVV

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: JN47
SO8OO receiver locator: KN09VW
Locator-centre separation: 975 km (approx.)
Last such locator decoded: 2026-07-24 12:39 UTC

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

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.
