Abstract
The daylight radio transmission conditions across the North Atlantic Ocean in 1930 for wavelengths of 10,000 to 20,000 m (15-30 kc) are shown in a table based on the daily observations of the signal strength of seven European high power stations taken in Washington. It is expected that similar tables of daily transmission conditions for the years beginning with 1924 will soon be ready for publication. The object of this form of tabulation is to furnish a ready means of comparison of radio conditions with other natural phenomena-sun spots, magnetic storms, weather, etc.Keywords
