DH1TST — 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: Fed. Rep. of Germany Most frequent locator attributed to this token: JO62

Receiver-side FT8 activity involving DH1TST, decoded by SO8OO in southeastern Poland. 42 FT8 messages attributed to this token as transmitter, on 80m, 60m, 20m, across 3 UTC dates in the available aggregate history. Observed between 2026-08-31 and 2026-10-23.

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 42 FT8 messages attributed to DH1TST as the transmitting token by decoded message structure across 3 UTC dates in the available aggregate history. The largest monitored-band total was 60 m (48%), followed by 80 m (36%) and 20 m (17%). In this small sample, the estimated median decoder S/N was +1 dB; no usual signal pattern is inferred.

Observed FT8 message patterns

Attributed sample: 42 messages
Active dates: 3 UTC dates
Estimated median S/N: +1 dB
Estimated 10th-90th percentile: -6 to +7 dB
Recurring-pattern threshold: Not met

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 0, moderate (-15 to -9 dB) 0, strong (≥ -8 dB) 42.

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 DH1TST

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: JO62 · 10 decoded messages
SO8OO receiver locator: KN09VW
Locator-centre separation: 675 km (approx.)
Last such locator decoded: 2026-10-23 08:28 UTC

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