Yadro-1A1 is an onboard HF (high-frequency) aircraft radio station designed for long-range simplex radiotelephone communication. The radio is used in civil and military aviation to provide reliable voice communication between aircraft and ground air traffic control stations over extended distances.

The radio station provides channelized, preset, non-tuned communication, allowing operation without manual frequency search or receiver tuning. Operation in the HF band enables long-distance communication beyond line-of-sight, including routes with limited ground infrastructure.

Yadro-1A1 operates in the frequency range from 2.000 to 17.999 MHz with a frequency step of 100 Hz. The transmitter peak output power is not less than 100 W, ensuring stable long-range communication. High receiver sensitivity allows reliable reception in various HF voice modes.

The radio station is powered from the aircraft 27 V DC onboard electrical network with a permissible voltage deviation of ±2.7 V. Yadro-1A1 is installed on helicopters such as Mi-8 and Mi-17, as well as on other aircraft equipped with HF antenna systems.

The Yadro-1A1 system is supplied as a complete radio communication complex consisting of multiple functional units for signal transmission, amplification, antenna matching, and control. Technical descriptions and operating manuals are available for the system, including the Yadro-1-RTE documentation.
