SO8OO display ranges among successful decodes: weak (≤ -16 dB) 117, moderate (-15 to -9 dB) 154, strong (≥ -8 dB) 1,260.

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.
