Like other television programming, sign-on and sign-off sequences can be initiated by a broadcast automation system, and automatic transmission systems can turn the carrier signal and transmitter on/off by remote control. [a] Sign-on and sign-off sequences have become less common due to the increasing prevalence of 24/7 broadcasting.
A digital signal controller (DSC) is a hybrid of microcontrollers and digital signal processors (DSPs). Like microcontrollers, DSCs have fast interrupt responses, offer control-oriented peripherals like PWMs and watchdog timers, and are usually programmed using the C programming language, although they can be programmed using the device's native assembly language.
The ratio of power of the analog signal to the digital signal was initially standardized at 100:1 (−20 dBc), i.e., the digital signal power is 1% of the analog carrier power. This low power, plus the uniform, noise-like nature of the digital modulation, is what reduces its potential for co-channel interference with distant analog stations.
On August 10, 2015, KFI began a simulcast on KOST's HD 2 signal. KFI served as the flagship station of the Los Angeles Chargers, carrying all of the team's game day broadcasts from the team's return to the Los Angeles market in 2017 until 2020, when games were moved to co-owned 98.7 KYSR .

Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
KKLQ-HD1 is a digital simulcast of the analog signal. KKLQ-HD2 broadcasts Air1, a contemporary worship music network with some contemporary Christian music, which is used for the feeder signal for EMF's Air1 translator network in Los Angeles and Orange counties. KKLQ-HD3 airs Radio Nueva Vida, a Spanish-language Christian teaching and music ...
