YM7KK — reception at SO8OO
Signals decoded by SO8OO in southeastern Poland. FT8 and CW have separate histories; all times are UTC.
FT8 activity
Receiver-side FT8 activity involving YM7KK, decoded by SO8OO in southeastern Poland. 12 FT8 messages attributed to this token as transmitter, on 80m, 40m, 20m, across 4 UTC dates in the available aggregate history. Observed between 2026-07-05 and 2026-11-02.
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 12 FT8 messages attributed to YM7KK as the transmitting token by decoded message structure across 4 UTC dates in the available aggregate history. The largest monitored-band total was 40 m (50%), followed by 80 m (33%) and 20 m (17%). In this small sample, the estimated median decoder S/N was -21 dB; no usual signal pattern is inferred.

Observed FT8 message patterns
- Attributed sample
- 12 messages
- Active dates

- Estimated median S/N
- -21 dB
- S/N percentile sample
- Too small
- Recurring-pattern threshold
- Not met
SO8OO display ranges among successful decodes: weak (≤ -16 dB) 11, moderate (-15 to -9 dB) 1, strong (≥ -8 dB) 0.
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).
Frequent counterpart tokens observed at SO8OO
Tokens most often paired with YM7KK in decoded directed-looking exchanges:
Most frequent locator attributed to YM7KK
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
- KN90 · 5 decoded messages
- SO8OO receiver locator
- KN09VW
- Locator-centre separation
- 1,701 km (approx.)
- Last such locator decoded
- 2026-11-02 20:45 UTC
A decoded locator can describe portable, remote or special-event operation and is not proof of a permanent station address or transmitter identity.
