G1ZRN — 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: England Most frequent locator attributed to this token: IO82

Receiver-side FT8 activity involving G1ZRN, decoded by SO8OO in southeastern Poland. 95 FT8 messages attributed to this token as transmitter, on 160m, 80m, 60m, across 4 UTC dates in the available aggregate history. Observed between 2026-10-08 and 2026-11-07.

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 95 FT8 messages attributed to G1ZRN as the transmitting token by decoded message structure across 4 UTC dates in the available aggregate history. The largest monitored-band total was 60 m (89%), followed by 80 m (9%) and 160 m (1%). Several six-hour UTC windows tied for the largest share (53%), so no unique busiest interval is claimed. Most successfully decoded messages attributed to this token fell in SO8OO's moderate S/N range (71%); the estimated median was -11 dB.

SO8OO display ranges among successful decodes: weak (≤ -16 dB) 8, moderate (-15 to -9 dB) 67, strong (≥ -8 dB) 20.

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 G1ZRN

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.

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