Problem statement. Existing radio transmitting devices use a non-tunable baseband filter focused on achieving a minimum level of out-of-band radio signal radiation, which leads to a decrease in the efficiency of using the energy resource of the radio transmitting device caused by an increase in the peak factor.

Purpose. improving the efficiency of using the energy resource of the radio transmitting device is adaptive dynamic control of the parameters of the spectrum of the radiated radio signal of the radio transmitting device, depending on the results of monitoring the electromagnetic environment.

Results. The proposed technical solution will make it possible to increase the efficiency of using the energy resource of the radio transmitting device by adaptive dynamic control of the parameters of the spectrum of the emitted signal, depending on the results of monitoring electromagnetic compatibility in the radio frequency bands of out-of-band radiation of the radio transmitting device.

Practical significance. The results can be used by specialists in the field of radio communications and radio navigation in the development of radio transmitting devices with a reduced level of out-of-band radiation.
