Communicating during an emergency may be essential not only for survival, but to help locate loved ones and garner news about an unfolding scenario.
Cell phone signals and Internet access are typically the first “services” to cease operating during either a natural or man-made disaster, and landlines may not be far behind. The GPS gadgets so many people rely upon to get to point B from point A will not be helpful if they are built into your vehicle and roads are clogged or something like an EMP attack has rendered the big hunks of metal useless.
Here are some alternative forms of electronic communication. (Keep in mind that building a Faraday cage may be necessary to protect what you own.)
1. Citizens Band Radios
CB radios can allow you to contact folks living many miles away, depending upon the quality of the device. Despite all the modern technology now available at our fingertips, the vast majority of truck drivers still have CB radios in their tractor-trailers – just like in the cult classic Smokey and the Bandit. Using a Citizens Band radio to find out what is going on not only in the extended region, but on the road you travel home, will help you avoid getting mired down in any traffic that is still moving and to avoid problem areas.
Never used a CB radio? Here are some tips from TruckerCountry.com:
The squelch is the control gate for incoming signals. This control cuts off or eliminates receiver background noise [white noise] when you’re not receiving an incoming signal. You can either set the squelch so that you receive all signals within your range, or so that you can only receive the strongest signals, usually those signals closest to you. Turn the squelch control clockwise to close the gate and only allow the strongest signals to enter. Turn the control counterclockwise to open the gate and allow all signals to enter. The desired squelch setting [DSS] is achieved by turning the control counterclockwise until you hear background noise, then turn the control clockwise just until the noise disappears. This is a good listening level.
2. 2-Meter and 10-Meter Radios
The 2-meter radios offer the ability to contact local law enforcement authorities and first responders. Monitoring rescue and recovery efforts, and any evolving unrest, will likely also be beneficial to the family’s survival. Some claim that 10-meter radios have allowed them to speak to others living several hundred miles away, but such ability would likely vary dependent upon location and terrain around the home.
3. FRS and GMRS Radios
The Family Radio Service (FRS) was enacted in 1996. During the past decade or so multiple businesses have also begun using the radio frequencies for communications throughout the workday. FRS radios were an improvement on standard walkie-talkie and allowed frequencies to be “channelized.” Both FRS and General Mobile Radio Service (GMRS) radios utilize ultra-high frequencies, or UHF. Most versions of the radio come with squelch codes known as DCS CTCSS. This attribute permits users to squelch out most unwanted transmissions from transmitting radio traffic, which conserves the life of the battery. FRS radios must have a permanent antenna to function and are restricted to 500-milliwatts. The typical range for such a radio is about one-fourth to one and a half miles – depending upon the surrounding terrain. GMRS radios can have an extended transmission range, also still dependent upon the geographic area.
Channels 1 through 7 are shared between FRS and GMRS usage.
Channels 8 -14 are designed for FRS only.
Channels 15-22 are reserved solely for GMRS and require a license by the FCC to use.
4. HAM radios.
The HAM radio has played an integral role in every disaster this nation has faced for over 100 years. HAM will remain functional even when modern communication devices become worthless. The seemingly old-fashioned devices are extremely reliable and allow users to connect with the outside world when Internet access, cell towers, and phone land lines are no longer functional.

HAM radio codes
QRL – The frequency is busy, do not interfere. Also used to ask if the frequency is busy.
QRM – An abbreviation for interference from other radio signals.
QRN – An abbreviation for interference from either man-made or natural static.
QRO – A request or alert to increase power.
QRP – A request or alert to decrease power.
QRQ – A request or question to send information faster.
QRS – A request or question to send information more slowly.
QRT – A question or request to stop sending information.
QRU – A response or question about the availability of sending more information.
QRV – Either, I am ready, or are you ready?
QRX – Standby.
QRZ – A request for identification of information sender.
QSL – Received and understood.
QSB – Signal is fading.
QST – All call before a message to all amateur HAM radio operators.
QSX – I am listening on “insert kHz frequency.
QSY – Change to “inset kHz frequency.
QTH – Use to request a location or as an alert prior to giving a location.
5. Weather Radios
NOAA weather radios are also an important item to consider. The broadcasts by the agency share weather and related emergency information designed for specific listening areas. There are approximately 425 NOAA transmitters currently active in America, the US Virgin Islands, Puerto Rico, Saipan, and Guam. Canada has its own version of the weather alert system, one which can be reached via the Internet.
Each NOAA transmitter covers roughly 40 miles from the device site. About 80 percent of the United States is included in the NOAA transmitter area. Typically, the weather alert agency’s broadcasts are on air 24-hours a day and updated when special warnings or hazards become apparent. During times of severe weather, amateur HAM radio operators contact the NOAA weather system on specific radio frequencies to offer local updates. NOAA operates on seven different frequencies outside of the typical AM/FM radio bands:
