...suitable wave length for the Harvard-station, WIDMW. So far as is known, this station, located in the Geographical institute building, will be the only station in the world officially in communication with Admiral Byrd on his coming expedition although numerous amateurs will doubtless pick up his messages. The antenna system on the station here will, in the near future, be altered so as to direct impulses to the south instead of radiating them in all directions...
Unheralded and unsung, Dr. Eckener's old Graf last week, on regular schedule, completed her third round-trip to Pernambuco, Brazil. Only one delay marred her winter season.

...France made the test. Simple equipment did the work. Sending and receiving devices were practically the same. Each device consisted of a vacuum tube which transformed telephone frequency into the high micro-ray frequency of 1,600,000,000 oscillations a second. Wires carried the oscillations to an antenna two centimetres (less than one inch) long. The antenna was fixed at the focal points of two curved reflectors which faced each other. One, facing in the direction messages were to be sent, was ten feet in diameter. The other suggested a motorcar headlight. The two reflectors concentrated the waves which...
