An AN/GRT-3 transmitter provided the modulated signals to a UHF Klystron high power amplifier: 2.19 —dual chains of components provided redundancy, including 2 exterior GAT Antennas on GAT Towers from which a missile's "command receiver" demodulated the signal. A single local monitoring cabinet allowed review of either chain's function (e.g ...
WSPR implements a protocol designed for probing potential propagation paths with low-power transmissions. Transmissions carry a station's callsign, Maidenhead grid locator, and transmitter power in dBm. The program can decode signals with a signal-to-noise ratio as low as −28 dB in a 2.5 kHz bandwidth.

The Katanga TV tower near Jabalpur, Madhya Pradesh, in central India hosts a high-power transmitter for the public broadcasters Doordarshan and Prasar Bharati. The Stuttgart TV tower was the first tower in the world to be built in reinforced concrete. It was designed in 1956 by the local civil engineer Fritz Leonhardt.
A radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. Radio waves are electromagnetic waves with frequencies between about 30 Hz and 300 GHz. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the ...
