átjátszó

Átjátszó is a Hungarian term that translates to "relay" or "transponder" in English. It is most commonly used in the context of radio communication. An átjátszó acts as a receiver and transmitter, picking up a signal from one device and rebroadcasting it, often at a different frequency or with increased power. This allows for extended communication range, particularly in areas with natural obstructions like hills or buildings, or for connecting disparate communication systems.

Amateur radio operators frequently utilize átjátszók to improve the reach of their signals. These devices can be fixed in strategic locations to create a network of communication coverage. In professional settings, such as emergency services or private mobile radio systems, átjátszók are essential for maintaining reliable communication over large geographical areas. The term can also be applied more broadly to any device that receives a signal and retransmits it, though its primary association is with radio.
