Emergency Radios Can Be Essential to Survival
An everyday AM/FM battery powered radio may not be enough to keep your family safe. Once you understand the difference between a radio and an emergency radio you will understand how the difference can be critical to your family’s safety. FEMA (Federal Emergency Management Agency) has recommended an emergency preparedness kit including important items that families should have in the event of an emergency. First and second on the list is water and food, obviously. The third item on the list is an emergency radio. FEMA’s definition of emergency radios is a “battery-powered or hand crank radio,” as well as, “an NOAA Weather Radio with tone alert.” Fortunately, radios are now available with all the necessary emergency features on one receiver.
Using FEMA’s definition and recommendations, let’s examine what type of emergencies you might be subject to and just what kind of radio you should have in order to be safe. If you live in an area where you could experience sudden dangers, as with the central United States known as tornado alley, then you need a radio that will provide instant information as soon as the National Weather Service broadcasts a warning. You will need a radio that provides S.A.M.E. (Specific Area Message Encoding) technology which can be programmed to receive emergency weather broadcasts in your specific area, as well as, NOAA weather information with a Weather Alert feature. Both of these features on a radio will automatically turn the radio on, send an alarm through the radio, and provide you with important information you need to have immediately.
Coastal Communities also have an essential need for the right type of emergency radio. Hurricanes are tracked for a number of days before they arrive on land and families generally have time to prepare or leave an area in the path of the storm. In this case you may determine that a weather alert feature isn’t as important and decide to settle for a radio that will keep you connected to the weather channels or local broadcasts when you choose to be updated. Severe storms and thunderstorms, although they can be dangerous to life and property, do not equal the urgency of a tornado. However, if you are camping with family or friends you may feel that having a radio with NOAA Weather Alert is important so you can be informed of severe weather, flash flooding, or subsequent dangers in your remote location.
The Inner Workings of Satellite Radio
Any song you hear on satellite radio stars as a recording in a specific format on different recording mediums. IN most cases, the recording quality has to be maintained fairly high, usually around 384kb/s, while also being reasonably small enough to be transported on CDs and DVDs. The music tracks used in satellite radio are cataloged using a similar system to the MP3 cataloging criteria, the ID3 tags. The choice for the music tracks that will be played is made by each channel individually. The DJ selecting the tracks usually chooses about 20-30 minutes worth of music. The DJ has to listen to the tracks to make sure they are in proper condition and then simply lets the computer decode the original file. The same thing is repeated once the initial 20-30 minutes are exhausted and the music playing cycle repeats itself.
Sound encoding in satellite radio
Encoding is one of the key elements of digital radio. Each channel is handled by a different encoder. The encoder basically takes the analog file and turns it into a digital one. The digitalization process is made in real time and the music files are transformed into 1′s and 0′s. This process is carried out by powerful computers that analyze sound waves and frequency and break them into binary code. The encoding process is carried out at 128kb/s, 44.1Kh which is actually CD quality. After the song is encoded, it is transmitted to a multiplexer where other channels are also present – the multiplexer basically takes all the channels of the satellite radio provider and combines them into a single broadcast transmission. The data is then sent to a satellite modem device which modulates the data and sends it to the broadcaster’s satellites, using unique transmission frequencies.
