Subsequently, the radio station was upgraded several times to the R-855-2M, R-855U, R-855UM and other options. The first radio stations were assembled on rod lamps, followed by transistors. In addition to the model, the radio stations also had configuration options A, B, C. A helmet could be connected to the radio station. The operating frequency of the radio station is 121.5 MHz. Transmitter power 100 MW. Sensitivity 5 μV. The detection range of signals from an altitude of 10,000 meters reached 300 km.
