Radio Brings Famous Teachers to Class
THE day when the President of the United States, or any other person of prominence, may address all the school children of the nation simultaneously is not far distant.
Schools throughout the country have already taken cognizance of the educational opportunities offered through radio broadcasts. The most prominent teachers of the world can be brought to any classroom with radio.
Police Inaugurate Two-Way Radio
THE first two-way police radio equipment in the United States is now in operation at Piedmont, a fashionable suburb of Oakland, California. Permission for this efficient new form of communication between police officers in the field and headquarters has been granted by the federal radio commission.
Portable Radios for U. S. Cavalry
THE latest in portable radio receivers and transmitters has been developed by Signal Corps engineers for use by the U. S. Cavalry. The antenna is strung on a short mast, while the instruments are carried on the saddle, as illustrated below.
The Amateur in the Making
By Walter Burnett

WHEN Marconi completed experiments a number of years ago, which made wireless telegraphy practicable, an unbelieving world sat up and gasped.
The wonder of his achievement lingered in the minds of many for a few days and then died. In certain young men, however, it created the spark of ambition, which flared up into an irresistible desire to enter into this new and practically unknown field. As a result nearly every city in the country boasts (or tolerates) its wireless amateurs.
Super Radio Set Will Tune In Any Of World’s Programs
JUST about the largest radio receiving set to be made so far is the latest creation of E. H. Scott. Night or day it will tune in any broadcasting station in the entire world
The receiver has forty tubes, and there are five loud speakers in combination to give the best reproduction possible on all tone frequencies.
World’s Smallest Complete Radio Broadcasting Station
THE City of Brotherly Love now boasts of the world’s smallest radio broadcasting station. Not much different in size and appearance from a household refrigerator, this station is accurate in all respects, operates entirely under its own power, and has a sending radius of two hundred feet with its 1/400th of a watt power plant. Its call letters are WEE, and it is owned and operated by the Tiny Broadcasting Company, operating on a frequency of 1,300 kilocycles.
The transmitter was designed and built by the Mystery announcer of WPEN, who recently won the title of the most popular radio announcer in a nation-wide contest.
Antenna Now a Loud Speaker
RADIO “freaks” or hearing of programs without apparatus, are reported occasionally; but are usually hard to verify. However, an occurrence at the Hilversum (Holland) station, reported by no less an authority than Dr. Balthasar van der Pol, in a letter to Nature, is well authenticated by competent observation.
Radiophone to Rid Siberia of Wolves
RADIO telephones placed at intervals throughout the wolf-infested regions of Siberia so that the whereabouts of these dangerous pests can be easily discovered is the latest means proposed by Soviet officials to rid the vast plains of the country of the wolf menace, long an obstacle to settlement and safe travel.
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. A new two way radio telephone, especially designed, for installation in fishing boats has now broken down this barrier of space, permitting the sailors to speak to their friends and families ashore.
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.
