transmit

Here the point is direction: transmit is the half of radio talk whose partner is receive. A set that transmits is sending, and one that receives is listening. The verb works with or without an object. A station simply transmits, or it transmits a Mayday call. In the passive, the sender is introduced with by, as in a call transmitted by the stricken vessel. Compare the self-propelled use, where the call itself becomes the subject.

Latin trānsmittō is built from 'across' and 'send', and English kept both halves when Middle English borrowed it as transmitten: something crosses a gap, and someone or something does the sending. The usual pattern is transmit something to a person or place, often with a word naming the route, as in transmitting documents directly to an embassy. The later senses apply this same crossing to new kinds of cargo.

Engineering's version of the word: a force or energy passes through a part, rather than a message passing between people. It sits comfortably in the passive, with to marking where the force arrives and through naming the part that carries it. The article “The first hundred 25 kV a.c. electric locomotives for B.R.” (1960) describes tractive and braking forces "transmitted to the body through a downward projecting pivot pin."

Here the message moves on its own: the thing sent becomes the subject, and no sender appears. A Mayday call transmitted successfully, just as a door opened or news spread. Contrast the sending-out sense, where the call is transmitted by someone. An adverb of outcome, speed or distance usually completes the clause: successfully, instantly, farther.
