Qst Devoted Entirely To Amateur Radio October 1943 (Vol. XXVII No. 10), American Radio Relay League
1 American Radio Relay League Qst Devoted Entirely To Amateur Radio October 1943 (Vol. XXVII No. 10)
West Hartford, CT American Radio Relay League 1943 1st Edition; 1st Printing Magazine Good+ 
B&W Illustrations; This is a trade sized magazine in Good+ condition and was issued without a dust jacket. The rear magazine cover has cracked nearly completely and there are several small chips missing. The text pages are clean and bright. "Amateur radio (also called ham radio) describes the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest; " (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire) , or professional two-way radio services (such as maritime, aviation, taxis, etc. ). The amateur radio service (amateur service and amateur-satellite service) is established by the International Telecommunication Union (ITU) through the International Telecommunication Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with an identifying call sign."

"Wireless telegraphy is a method of conveying written or typed ("graphic") information over a distance ("tele") using established telegraphic techniques but without the use of interconnecting wires. Although it is now used as a historical term for early telegraphic systems which employed radio waves as the communication medium, when the term originated in the late 19th century it also applied to other types of wireless telegraphy, such as photoelectric and induction telegraphy. Wireless telegraphy came to mean Morse code transmitted by radio waves, discovered by Heinrich Hertz in 1886 (and thus initially referred to as "Hertzian waves"). The primitive spark gap transmitters used until World War 1 could not transmit audio signals. Instead the operator would tap out the code on a telegraph key, turning the transmitter on only while the key was depressed and thus producing short ("dot") and long ("dash") pulses of radio waves, groups of which comprised the letters and other symbols of the Morse code. Under appropriate conditions (proximity, weather, etc. ) , the signals could be heard in the earphones of the receiving operator who would translate them back into text."

Graphs; This book is in Very Good+ condition and was issued without a dust jacket. The book and its contents are in mostly clean, bright condition. There is some ground-in dust to the composite covers. The text pages are clean and bright. "Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. [n 1] When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form. Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and radio waves into an electric current. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form that is usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions, etc."

There is some ground-in dust to the composite covers. The text pages are clean and bright. "In radio communications, a radio receiver (radio) is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation."
