The discovery of the technique of modulating a radio-frequency (RF) signal initiated the journey of the ever-evolving military communications field. However, RF modulation was a mere scientific curiosity until hardware improvements and better understanding of the nature of modulated signals triggered the development of practical and continuously improving military radios. Examples of hardware improvements in the early stages of military radios include the use of the micrometer spark gap, magnetic detectors, and electrolytic capacitors. The development of vacuum tubes and the three-electrode tube used for signal amplification made possible a well-connected battlefield.
