In the modern Marconi system the energy for the transmitter is obtained from a generator working at one hundred and ten volts.
A microphone transmitter is employed with this apparatus.
These phenomena even permitted a true telegraphy without intermediary wire between the transmitter and the receiver, at very restricted distances, it is true, but in peculiarly interesting conditions.
The synchronism of the two pieces of apparatus, the transmitter and the receiver, is not perfect, so that a message sent off by one station may be captured by some other station.
A transmitter and not a maker, believing in and loving the ancients, I venture to compare myself with our old P'ang [1].
Emphatically he was 'a transmitter and not a maker.

All things equal, then, a telephone transmitter will be so much the more potent in proportion as the lines set in motion by the vibrations of the disk and meeting the bobbin wire are greater in number.
Stations wholly magnetic may be established by adding to the transmitter and two receivers a Sieur phonic call, which will actuate them powerfully, and cause them to produce a noise loud enough for a call.
