What reading level is Elements of Radio Telephony book?
To quickly assess the difficulty of the text, read a short excerpt:
If the transmitter does not alter its resistance the value of the direct current flowing through the circuit will remain unchanged and the telephone receiver diaphragm will not vibrate; only when the current is changing in value is any sound transmitted and the modulator in radio telephony is the device that varies the output of the set in accordance with the sound wave that it is desired to transmit.
There are two general schemes which are employed in radio telephony, in the first one the tube... delivers a constant power output and the transmitted wave is varied in ampli- tude by changing conditions in the antenna circuit; the second one does not vary antenna conditions but controls the output of the tube in accordance with the sound wave to be transmitted.
Modulation by Antenna Control. The simplest case of modulation by antenna control is illustrated in the use of an ordinary telephone transmitter or microphone connected directly in the antenna circuit. The telephone transmitter, as has been pointed out, is a device which changes its resist- ance to correspond with the sound waves impressed upon its diaphragm, hence the transmitter connected directly in series with the antenna will cause the current to rise and fall as the resistance decreases and increases.
