We finally have a station identification for the mysterious 1800 UTC fishery fax on the common Japanese frequency of 8658.0 kHz USB. Most of the time, it is all in Japanese, and so weak that only the black bar is visible. Here, however, we have a clear ID for JFX, Kagoshima Prefectural Fishery Radio, Japan.
The NOAA reference is less clear. It's no doubt the US National Oceanic and Atmospheric Administration, which is the American weather agency. The columns are obviously grouped by date and area, but the numbers appear to be some kind of coded forecasts for February 15-17.
Presumably, this and other such faxes sent on the fishery frequencies, which also include 6414.5, 16907.5, and 22559.6 kHz USB, are information for the fishing fleet.
All fax signals are tuned 1.9 kHz lower than their listed frequencies.
