Three different bureaus of the gov- ernment are rushing work to perfect telephone radio sets for transmitting from airplanes in flight. Such trans- mission is, of course, not new, but efficlent sets answering specific re- quitemets are desired by the Army air service, the Marine Corps and the post office air mall service. The prob- lem cannot be worked out jointly, since the specifications are not simi- lar. Ever since the armistice the Army has been trying to develop a combina- tion radio telephone and telegraph set suitable for airplane use, and has just about eucceeded. Recent tests with model set S. C. R. 134, between an afirplane flown back and forth from Bolling Field, Anacostia, D. C. to Quantico, Va., about forty-five miles, and the radio laboratory of the fgnal Corps in Washington,” proved the set was practically perfect. Out- | siders listening-In on lhe two-way | conversation were de interested, | following the engineers’ conversation carried on over NAA at Arlington, | and then picking up Capt. Johnson's | replies on 400 meters from the plane. | The sample transmitter bullt by the | General Electric Company was found fo be satisfactory, the main object being the motor alternator, which furnishes the tone for the interrupted C. W. transmission, which, it ia felt, can be readily corrected and produc- tion orders placed. Marine Corps radio and aviation ex- perts recently tested out a new serv- ice combination set for use in air- planes, but without very successful results, due chiefly to bad weather onditions requiring low flying. Con- versation between officers in the Navy hullding, however, and Capt. Pierce in a plahe over Quantico was carried on, but further tests will be nece sary. What the marine flyers wani is a ehort-wave telephone set using around 100 meters, whereas they have been forced to use - transmitting wave of 500, which theyjclalm is too long and productive of harmonics. (avy set 1345 is therefore being modi- fied” and improved. Other tests in spotting practice held at Quantico, wherein a plane gave phone reports on target practice, proved satisfac- tory. The operator in the plane was heard as far away as Baltimore by radio fana who were listening in. For air-mail pilots, who fly alone on their trunscontinental trips. the Post Office Department s seeking a “one-man” radiophone set which can Le operated by the pilot while under- | way. Radio telegraphy is useless for routes, in the opinion of postal uthorities, since they haven't room for an operator and do not require their pilots to ode. Radlo telephony, the carries the whole burden of alding in aerial flight, getting orders, calling for a and directions. A special small and compact telephone transmitting set to operate on about 125 meters Is de- sired. Tests have just been made on new set developed by the General Electric Company operating on 15¢ to 280 meters. Speech Is sent out through five ffty-watt XL transmit- ting tubes. The recelver uses seven r tub. The operation and adjustment ix simple, aud the trans fer from sending to receiving is made by throwing a switch. After a year's work a practical standard set has been adopted and an appropriation providing fo set for each plane will be sought. The necessity of small « and welght was one of the difficult problems, but it had to be solved In the interest of carrying as much mail as was possibl enough, opposite view communication authorities; naval fivers have practically abandoned the telephone set and use only radio telegraph. all the pilots being skilled in code trans- mission Ship Stations Interfere. the elimination of amateur ence with broadcast 1pcep- tion through the government regula- tion providing for evening ‘“quict hours” the Department of Commerce is now faced with a serious situation that threatens the pleasure of many thousands of listeners—namely, the interference which is being caused nightly by scores of ship telegraph stations It was comparatively an easy mat- ter to obtain the co-operation of the amateur through his organization, the American Radio Relay League, buti the proposal to keep silent ship radio stations that are handling life and death messages is another matter. Ship transmission is vital to safety at sea and to commerce. One the one hand are thouxands of listeners clamoring for relief from | interference that is spoiling their concerts and on the other the posi- | tively al ship and commercial ir traffic. Commercial stations, both ship and shore, use that band tween 300 and 3,000 meters. The Navy cmploys waves from 600 upward, while the Army. which causes very ttle interferenc llows the Navy. Among the national organizations which have announced their inten- ¢lon of bringing thls matter he- fore the Department of Commerce of- ficlals is the National Association of adcasters, the executive chairman Paul B. Klugh, savs: “We that ship-to-shore and com- stations on radiophone wave- | during popular broadcasting ar. al disturbance to un- interrupted reception.

Now it iw fast pas from the realme of romance and novelty into the provinces of utility and depend- bility. But romance and novelty re reluctant to give place to the inevitable practicality which keeps such business prospering and expand- ing. Consider this request made of the program manager at WRC.

This s, of course, true, but T believe it is likely to give a wrong Impression 1o a person who is not familiar wit crystal de- tector. Instead, it should be defi- nitely stated that in no case is a battery used for galena or silicon detectors. Radiocite rade name and name of a mineral at not familiar with boroni pyrites should have been tioned, for it is frequently and requires no battery.
