Fishermen Now Radiophone to Families (Feb, 1933)

Fishermen Now Radiophone to Families

DEEP sea fishermen spend a large portion of their lives isolated on the ocean, out of touch with land for days and days on end.

How the combined receiver and transmitter operates is illustrated in the artist’s drawing above. No trained radio man is necessary to put through a call. The fisherman simply presses a button and connects up with a land station, which hooks him up to the city telephone system. Engineers are planning on installing many of these instruments on American fishing boats cruising the East coast areas.
