FIELD: information technology.
SUBSTANCE: method for telegraph radio communication is characterised by that a series of electromagnetic waves of the same frequency and amplitude is simultaneously transmitted from a signal transmission point to a signal reception point, where neighbouring waves in the series are phase keyed in accordance with the transmitted message by an angle equal to the ratio of 360 degrees to the number N of emitted electromagnetic waves. The apparatus has a series of identical power amplification channels, each having a phase-shift circuit, a power amplifier, a matching device, an antenna and an electronic phase keying key.
EFFECT: high power capacity of the power amplification channel of the transmitter due to reduced current surge during phase keying.
