KFBK in the California still maintains an RCA BTA-50H (the "last gasp" of the Ampliphase concept) as an auxiliary transmitter. However, KFBK's main transmitter is a solid-state Harris unit, a prototype for which later renamed the DX-50. KOH has long since scrapped its home-built "outphasing" transmitter for conventional units.
It is clear that electric field strength is inversely proportional to the distance between the transmitter and the receiver. However, this relation is impractical for calculating the field strength produced by terrestrial transmitters, where reflections and attenuation caused by objects around the transmitter or receiver may affect the ...
A broadcast transmitter is an electronic device that radiates radio waves modulated with information content intended to be received by the general public. Examples are a radio broadcasting transmitter which transmits audio (sound) to broadcast radio receivers (radios) owned by the public, or a television transmitter, which transmits moving images to television receivers (televisions).
Midway through the 4-Line's run, in 1967, Drake introduced a receiver and transmitter pair meant for the Novice licensee - the 2-C receiver and 2-NT transmitter. The 2-C was an improved receiver based on the 2-B design using a few more solid state devices. Thus, it was a sophisticated design compared to most other receivers targeting Novices.
A modern HF transceiver with a spectrum analyzer and DSP capabilities. The transceiver first appeared in the 1920s. [citation needed] Before then, receivers and transmitters were manufactured separately and devices that wanted to receive and transmit data required both components.
The last 405 line transmitters in the UK and Ireland were shut down in 1985. The last 405-line relays, in County Donegal , were turned off in 1982; the main transmitters had been shut down in 1978 to free up frequencies for RTÉ 2 , and after then the relays had been fed by standards converters from the local 625-line transmitter.
This is a list of former CBUT-TV transmitters that were used by the Canadian Broadcasting Corporation to expand the coverage area of a station to include remote rural areas throughout the Canadian province of British Columbia. These transmitters served as rebroadcasters of CBUT's main signal that originates from Vancouver. Due to budget cuts ...
