I’m selling the emergency radio as a collectible because I don’t know how to test it for functionality.

Description of ss internet:
The aviation radio station "R-855" (Komar) has been produced since 1959. Serves for communication in extreme conditions in aviation, for communication between parachutists and the ground, in emergency and search situations. RS completed the suits of military pilots. When used in emergencies, when dropped on water, the kit, which included an inflatable antenna, was inflated with compressed air and the radio station began to emit an ''SOS'' signal. Subsequently, the radio station was modernized several times into ''R-855-2M'', ''R-855U'', ''R-855UM'' and other variants. The first PCs were assembled using rod tubes, the subsequent ones using transistors. In addition to the model, the radio stations also had configuration options A, B and C. You can connect a headset to the radio station. The operating frequency of the radio station is 121.5 MHz. Transmitter power 100 MW. Receiver sensitivity 5 µV. The detection range of signals from a height of 10 km reached 300 km.
