| Title | HF field strength measurement |
| Sub-Title | Data record and scaled value |
| Data Summary | The field strength of HF-JJY (HF standard frequency radio waves) transmitted from Japan were measured at Syowa Station. The receiver detects only the upper sideband component of the singnal in order to avoid the co-channel interference. Houry field strength were tabulated. Monthly median value was plotted with quatile range. |
