Cobra CB RADIOEven during small scale disasters (earthquakes, seasonal storms, etc.) your normal communications channels can become compromised. In fact, it doesn’t take much to bring down an entire cell network, making the ability to communicate during a disaster one of your top priorities.

While ham radio is always my first line of emergency communications, a C.B. Radio is another important part of any good survival communications plan.

Made popular during the 1970s, because of movies like Smokey and the Bandit, for decades C.B. Radio was one of the most popular forms of short distance communications. Although its popularity has faded, due to development of mobile phones, the internet and the Family Radio Service, it still remains extremely popular among truckers, radio hobbyists, and survivalists.

Citizen’ Band radio (better known as CB radio) is a short-distance radio communications that takes up 40 radio channels from 26.965 to 27.405 MHz. A properly tuned CB has a range of around 20-30 miles, but if illegally tweaked can transmit hundreds of miles.

  1. CBs have become quite popular again. We use standard VHF while fishing though that is dying more and more as people now use cellphones to communicate, which often work pretty far offshore. Though it’s required to have by the coast guard in the charter industry, and always a good backup!

  2. Butch says:

    If one were to want to get their C.B. radio illegall tweaked
    how would they go abou doing that?

    • Damian says:

      They would go about doing that illegally, however it’s only illegal if you get caught;)

    • Big Man says:

      CB Radio is ok for a few miles. Then you HAVE to lean on a Ham Radio Operator to get any kind of distant communications… Tweaking a CB won’t help as well as a decent antenna. DR-DIPOLE.COM makes a great survival antenna for the Ham Radios and for CB. Spend your money on a GREAT Antenna, not 20 or 30 more watts that won’t get you an extra couple of miles… Good luck.

        Those few miles are in the thousands with a decent radio and good antenna. I’ve worked almost every State from my truck, except Hawaii. Alaska, Ireland, England all from a pickup truck in Maine.

        • ashton harvey says:

          is it true that if you run enough power into a home base station that it can go as far as a ham radio?

    • mic says:

      Has a cb and a linear amp. Most truckers use linear amps to push the cb power up higher. Mine is 400 watts and is considered small by most truckers. I know of a guy who has 1,500 watts. On my 400 watt model I can talk approximately 50 miles consistently and further depending on weather, skip, propagation etcetc. Have talked all the way to California and Im in Georgia but thats not consistent.

      • John M says:

        The legal limit is 4 watts, right? Are you saying truckers pump out 100-300 times the legal power limit? Or am I misunderstanding how the numbers work

  3. Richard says:

    Go to any decent size Truckstop ,Many have a CB shop, Take your radio in and tell the guy what You want to do. Any good radio tech can do the work, works best with the better quality radios,if Your in an area with several truckstops there may be several shops in the area, get on the radio and ask the Drivers who does the best work, if You listen to channel 19 You can hear the difference between the stock radios and the ones that work real good

  4. Terry says:

    All fine and dandy IF you have electricity! Slar panels, car batteries, converters… make your own. Enough to run that radio. Search for it on youtube for a lot of DYI ideas for alt energy sources.

  5. meives says:

    do you need a licence for a cb radio?

    • DJKulp says:

      during the 70′s, a license was required … that changed mid 80′s. For Citizen’s Band Radios. HAM radio still requires a license.

  6. Badger359 says:

    You may consider applying the survival triangle or triad concept to the situation of “comms” or communications. 1/3 of your comms would be spread out this way. a)Ham radio “long range”, b)CB or SSB for mid-range and c) GMR’s for short range. Just a thought friends.

  7. Viktor Zimmerman says:

    Can you also transmit the CB frequencies on your ham radio and eliminating your CB radio?

    • Paul says:

      You can but its illegal if the FCC checks your equipment. AM Transmitions sounds bad using a ham radio.

  8. Brian says:

    “Tweaking” a CB radio is illegal if it allows the unit to transmit with more power and/or transmit outside of the defined channels.

    Unless it’s a life, limb, or property emergency, transmitting outside of licensed ham bands is illegal when using ham equipment.

    Also, avoid expecting GMRS (or FRS) radios to be able to attain their advertised distances unless you and the other person are on mountain tops. Average range for a “bubble pack” radio is probably 1 mile in the city, possibly 2 miles in a suburb barring any significant obstructions (hills, tree, buildings, etc). If you add an external antenna to the device (licensed GMRS only), you can extend that a bit further. Also, Motorola 355R (I think) can access repeaters and thereby extend their range significantly (like tens of miles). We ham radio operators use repeaters quite often to talk distances in the VHF/UHF ham bands. You can also purchase old commericial hand helds and mobil units that can be reprogrammed to operate in the GMRS bands and also use external antennas.

  9. Desmond says:

    Well I do know this about RADIOS’s
    using a modified CB (Citizen Band radio) is agenst the law
    trasmitting on CB with a HAM radio is agenst the law (it is Evan on the test for HAM)
    fmrs/gmrs I forget witch one is the licenced one but most who have them dont have a lenience for them.

    The other thing is in a emergency ALL RADIO COMMUNICATION is leagal (Property and life)

    FYI KF7KIP (Ham operator)

  10. sniper says:

    FYI adding a linear amplifer to a CB dramatically increases the radio range… but yes it is illegal…

    items can be purchased at radio shack… or ham radio dealers

    also check ebay and amazon

  11. Kevin says:

    Better than CB radio is HAM radio. its the same thing but on a wider scale

  12. Pamela says:

    Go to tenfourstore.com…. CB radios for way less then the cost of “radioshack….the dudes that work there are so young they dont even know what CB is …lol… i go to tenfourstore.com for all my CB needs … as in being prepared for the possible end of the world …LOL..i guess !!

  13. jimbillybob says:

    Im gona get mah radio strong so i can get drunk and broadcast my stupidity to as many people as i can. This is mah neat toy. Who cares if it interferes with folks using other technologies like da internet. Da goverment cant tell me what to day out ta get meh. Go Wallmart!

    • Scott says:

      Hey Bimjillyboob…stick to your hillbilly inbreeding partys and leave the surviving to those of us that matter

  14. Mike says:

    Two-way radios are good and depending on your needs will determine which type to get.

    Citizen Band (CB) radios are legally limited to 4 watts output power.
    The newer General Mobil Radio Service / Family Radio Service (GMRS/FRS) radios need to have a license for the 5-watt GMRS channels; technically the FRS channels have a lower power output limited to 500 milliwatts (half a watt) even on the same GMRS radio so if you only use the FRS channels, you do not need a license; but they are included in the same GMRS radio… so to ‘legally’ communicate on all of the channels you will still need a license from the FCC, currently costing $80 for five-years, no test.

    Even the HAM hand held radios are mostly 5-watt power output, but they get to go further by going through local repeaters with increased power. Also, with the license, the HAM operator can legally increase the output of their hand held radio based on the frequency range the operate within.
    The HAM radios in cars and home base stations will typically have the higher output and longer range on their own.

    Since the FCC no longer requires the Morse Code for the HAM license, if you are technically savvy in electronics, there are practice tests and study services you can find online, so it might be worth your efforts to study and get your HAM license, if only to be the ‘communications expert’ in your extended family.

    In my area, Chanel 15 @ 27.135 MHz is where mud ducks like to hang out ( people trying to make the most of running legal power ). If You are frustrated about not being heard without running a linear, this is the channel to listen to. Perhaps you could add a “legal power” comment to channel 15 on your list of channels, it would be nice if we could spread the word through out the country that there is a place where 4 watts can be heard. thanks, David aka KG2LI

  16. peter nielsen says:

    can some one tell me can we transmitte on 27 mzh the oz channel

  17. CUNTLAPPER says:

    I HAVE MET MANY EZ CUNTS TO FUCK ON CB RADIO

  18. Rattler says:

    I have been into CB for many years over 20. I have used it to contact mexico, CA,PA,Fl and many others this is done on SSB/LSB and bare foot. SSB/LSB use AM 10 meter spectrum there are a number of off spectrum channels that are open and unregulated just need to tune them in. you can even scramble and de-scramble for security vary easy.

  19. KG4RYT says:

    CB is a great survival radio. When the grid goes down CB will be king. I know i’m a HAM radio operator endorsing CB radio, but CB radio is best just because of the numbers they make a much better emergency radio. They are cheap, easy to use, and widely available. SSB is the best mode, but AM CB will do very well. Highway CB Channel 19 is king, try contacting someone on 2M 146.520 simplex about road conditions or any other traffic matter, When the grid goes down so do the repeaters. For off road CB is king, if you guys go off road in a 4×4 a CB radio is almost a must. Most amatuer rigs can not handle the abuse. FRS, GMSR useless.

    • chiefcrash says:

      That may have been true before, but these days it’s swinging back to ham radio. No morse code test + $30 chinese ham radios = explosion of new hams (and preppers playing with radios)

  20. Emily Taylor says:

    I have a galaxy 10 meter CB that putts out around 200 watts. Though I’ll lower it to around 40 (maximum driver watter for my linear) or so watts when using an amp to run it at 600-800.

    Running a wire dipole or 24 foot Imax veritcal I can talk all over the state pretty good on AM, when I switch to using USB I can go all over the country. Any further and I use a Moonraker 4 which I was lucky enough to find new in box on ebay. I’ve talked on 27.555 to the bottom of chile, australia, and china still 5-9.

    Local and statewide ragchews are great.

  21. SNIPER says:

    what about marine radios, since they use differant freqs, and everyone else is using cbs jamming up the airwaves and you need to talk is this a better option?

  22. Monty says:

    Is a cobra still a good CB set

Tell us what you're thinking...
