Yadro-1G1 is an onboard HF (high-frequency) aircraft transceiver radio station designed for simplex radiotelephone communication with ground HF radio stations and between aircraft in flight. The radio station provides preset, non-search, non-tuned operation, eliminating the need for manual frequency search and receiver tuning.

Yadro-1G1 is used on helicopters and other aircraft and ensures reliable two-way HF communication at distances of not less than 400 km at a flight altitude of 1000 meters. Operation in the HF band allows long-range communication beyond line-of-sight, including areas with limited ground communication infrastructure.

The radio station operates in the frequency range from 2.000 to 17.9999 MHz with a frequency step of 100 Hz. Transmitter output power ranges from 50 to 100 W, providing stable communication under various operating conditions. High receiver sensitivity ensures reliable signal reception in HF voice communication modes.

The Yadro-1G1 system is supplied as a complete radio communication complex consisting of a transceiver assembly, power amplifier, antenna tuning unit, control panel, mounting frame, and auxiliary power units. The radio station operates with a trailing wire antenna installed along the tail boom of the aircraft.

The radio station is powered from the aircraft onboard DC electrical network with a nominal voltage of 27 V and is designed for operation in a wide ambient temperature range.
