Abstract :
The chain of semi-high-power stations (25 K.W.) established by the Marconi Company at Ketchikan, Juneau, and Astoria in Alaska are described. The masts, insulation, antenna, power supply, rotary converter, discharger, and relay key of these stations are considered in detail. The climatic and radio stray conditions are shown to be unusual. Remarkable directive absorption is encountered. The favorable receiving conditions are illustrated.
