DZCA (1170 kHz Metro Manila) was an AM station owned and operated by the Office of Civil Defense in the Philippines. Its studios were located at Agham Rd., Quezon City.


In 1956, DZQL 1160 was launch it's airwaves by ABS-CBN. In 1960, DZQL frequency was now on 830 khz. In 1972, DZQL shutdown due to Martial Law by Ferdinand Marcos. In 1973 it revived by Office of Civil Defense, it once served as the official radio station of the Philippine Atmospheric Geophysical and Astronomical Services Administration or (PAGASA), given the latest weather information in the country at the top of the hour (after the station ID).

The station is defunct since 1993, due to lack of funding. Despite being inactive, the frequency receives live broadcast of Voice of America via DWVA in La Union. [1]

CONELRAD Former method of emergency broadcasting in the United States

CONELRAD was a method of emergency broadcasting to the public of the United States in the event of enemy attack during the Cold War. It was intended to allow continuous broadcast of civil defense information to the public using radio stations, while rapidly switching the transmitter stations to make the broadcasts unsuitable for Soviet bombers that might attempt to home in on the signals.

Longwave Radio transmission using wavelengths above 1000 m

In radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band. The term is historic, dating from the early 20th century, when the radio spectrum was considered to consist of longwave (LW), medium-wave (MW), and short-wave (SW) radio bands. Most modern radio systems and devices use wavelengths which would then have been considered 'ultra-short'.

Pirate radio or a pirate radio station is a radio station that broadcasts without a valid license.

NOAA Weather Radio 24-hour network of VHF FM weather radio stations in the United States

NOAA Weather Radio is an automated 24-hour network of VHF FM weather radio stations in the United States (U.S.) that broadcast weather information directly from a nearby National Weather Service office. The routine programming cycle includes local or regional weather forecasts, synopsis, climate summaries, synopsis or zone/lake/coastal waters forecasts. During severe conditions the cycle is shortened into: hazardous weather outlooks, short-term forecasts, special weather statements or tropical weather summaries. It occasionally broadcasts other non-weather related events such as national security statements, natural disaster information, environmental and public safety statements, civil emergencies, fires, evacuation orders, and other hazards sourced from the Federal Communications Commission's (FCC) Emergency Alert System. NOAA Weather Radio uses automated broadcast technology that allows for the recycling of segments featured in one broadcast cycle seamlessly into another and more regular updating of segments to each of the transmitters. It also speeds up the warning transmitting process.

VHF omnidirectional range Aviation navigation system

Very high frequency omni-directional range (VOR) is a type of short-range radio navigation system for aircraft, enabling aircraft with a receiving unit to determine its position and stay on course by receiving radio signals transmitted by a network of fixed ground radio beacons. It uses frequencies in the very high frequency (VHF) band from 108.00 to 117.95 MHz. Developed in the United States beginning in 1937 and deployed by 1946, VOR is the standard air navigational system in the world, used by both commercial and general aviation. In the year 2000 there were about 3,000 VOR stations operating around the world including 1,033 in the US, reduced to 967 by 2013.

Radio New Zealand Public-service radio broadcast network

Radio New Zealand, commonly known as Radio NZ or simply RNZ, is a New Zealand public-service radio broadcaster and Crown entity that was established under the Radio New Zealand Act 1995. It operates a news and current-affairs network, RNZ National, and a classical-music and jazz network, RNZ Concert, with full government funding from NZ on Air. Since 2014, the organisation's focus has been to transform RNZ from a radio broadcaster to a multimedia outlet, increasing its production of digital content in audio, video, and written forms.

Radio Amateur Civil Emergency Service

The Radio Amateur Civil Emergency Service (RACES) is an emergency radio service authorized in Part 97.407 of the Federal Communications Commission (FCC) rules and regulations governing amateur radio in the United States.

The X band is the designation for a band of frequencies in the microwave radio region of the electromagnetic spectrum. In some cases, such as in communication engineering, the frequency range of the X band is rather indefinitely set at approximately 7.0–11.2 GHz. In radar engineering, the frequency range is specified by the Institute of Electrical and Electronics Engineers (IEEE) at 8.0–12.0 GHz. The X band is used for radar, satellite communication, and wireless computer networks.

Distance measuring equipment

Distance measuring equipment (DME) is a radio navigation technology that measures the slant range (distance) between an aircraft and a ground station by timing the propagation delay of radio signals in the frequency band between 960 and 1215 megahertz (MHz). Line-of-visibility between the aircraft and ground station is required. An interrogator (airborne) initiates an exchange by transmitting a pulse pair, on an assigned 'channel', to the transponder ground station. The channel assignment specifies the carrier frequency and the spacing between the pulses. After a known delay, the transponder replies by transmitting a pulse pair on a frequency that is offset from the interrogation frequency by 63 MHz and having specified separation.

Radio jamming is the deliberate jamming, blocking or interference with authorized wireless communications.

Mobile User Objective System

The Mobile User Objective System is a narrowband military communications satellite system that supports a worldwide, multi-Service population of users in the ultra high frequency (UHF) band. The system provides increased communications capabilities to newer, smaller terminals while still supporting interoperability with legacy terminals. MUOS is designed to support users who require greater mobility, higher bit rates and improved operational availability. The MUOS was declared fully operational for use in 2019

Military Auxiliary Radio System United States civilian auxiliary service for military support

The Military Auxiliary Radio System (MARS) is a United States Department of Defense sponsored program, established as a separately managed and operated program by the United States Army, and the United States Air Force. The United States Navy-Marine Corps program closed in 2015. The program is a civilian auxiliary consisting primarily of licensed amateur radio operators who are interested in assisting the military with communications on a regional and national level when access to traditional forms of communication may no longer be available. The MARS programs also include active duty, reserve, and National Guard units; and Navy, Marine Corps units.

Kol Yisrael was Israel's public domestic and international radio service. It operated as a division under the Israel Broadcasting Authority, until 14 May 2017, and the following day the frequencies were handed over to the Israeli Broadcasting Corporation.

Weather radio

A weather radio is a specialized radio receiver that is designed to receive a public broadcast service, typically from government-owned radio stations, dedicated to airing weather reports on a continual basis, with the routine weather reports being interrupted by emergency weather reports whenever needed. Weather radios are typically equipped with a standby alerting function—if the radio is muted or tuned to another band and a severe weather bulletin is transmitted, it can automatically sound an alarm and/or switch to a pre-tuned weather channel for emergency weather information.

Amateur radio emergency communications

In times of crisis and natural disasters, amateur radio is often used as a means of emergency communication when wireline, cell phones and other conventional means of communications fail.
