Prima-400 airborne HF radio (ALE mode)

Family of airborne HF radio sets
Prima-400 radio sets are intended for telephone and datalink communication on fixed HF range frequencies between aircraft and ground communications centers. Prima-400 radios provide operation in the frequency range of 2.0000 to 29.9999 MHz with frequency spacing 100Hz.
There are different versions of Prima-400 – for civil aviation, as well as radio sets with adaptive communication.
