Continuing the CB Radio for Preppers and Caleb looks back to his teens and how CB Radio was what lead him to Radio Shack, FM Radio and Ham Radio and eventually Podcasting.
CB isn't what it was, but it's a Very Practical Comms Tool you should consider for your preps!

The 11-meter band sits within the **high-frequency (HF)** spectrum, and its properties significantly affect the performance of CB radios. Frequencies within this range can travel through the ionosphere, especially during favorable atmospheric conditions, making **skip propagation** possible. Skip propagation allows signals to bounce off the ionosphere, potentially reaching hundreds of miles beyond their typical range.
However, not all conditions favor such long-distance communication. Atmospheric disturbances, solar cycles, and interference from other devices can limit the effective range of CB radios operating in the 11-meter band. For most users, this range averages between **1 to 15 miles**, depending on the terrain and other factors.
AM vs. SSB Modes: Performance and Usage
CB radios typically operate using one of two communication modes: **Amplitude Modulation (AM)** and **Single Sideband (SSB)**. Both have their advantages and trade-offs, impacting how CB users experience clarity, range, and performance.
AM (Amplitude Modulation)
The AM mode is the default communication method for most CB radios. It works by modulating the amplitude of the radio wave to carry the audio signal. AM is relatively simple in terms of technology and is favored by truckers and casual users for local communication. However, it has limitations, particularly in clarity and range.
AM transmissions are more susceptible to **noise interference** from electrical devices, power lines, and atmospheric conditions. The sound quality tends to degrade over longer distances, and the range can be limited, typically extending no further than **5 to 10 miles** in most conditions. While convenient for general communication, AM may not offer the performance needed for long-distance or emergency communication.
SSB (Single Sideband)
SSB mode offers a significant upgrade in performance, allowing CB users to achieve greater range and clarity. Unlike AM, which transmits a full signal that includes a carrier and both upper and lower sidebands, SSB transmits only one sideband (upper or lower), removing the carrier. This makes SSB more **efficient** in terms of power and bandwidth usage.
In practical terms, SSB can extend communication range by **50 to 100%** compared to AM, making it ideal for those who need to cover larger areas. It also provides clearer audio, especially in noisy or interference-prone environments. The trade-off, however, is that not all CB radios support SSB, and it requires more precise tuning for optimal performance.

Beware/Aware: Most CB Radio Traffic is Rated R
[00:00:12] It is the Prep Comms podcast. I'm Caleb Nelson, K-4 CDN. I'm a ham radio guy. I also have a
[00:00:18] GMRS license. It's WRBR 237, a business itinerant, whatever back. I can't remember what it was.
[00:00:24] And back in the day, I was a ham radio operator. I was a CB radio operator and loved it. It
[00:00:30] was so fun as a teenager back in the day. Now, gosh, if you're less than 25 years old and you're
[00:00:38] listening to this, you're amazing. God bless you. Thank you so much for listening. Let me know. I'll
[00:00:42] send you something. Yeah, back when we were your age, we didn't have phones to stare at. So we
[00:00:47] actually would go out into public and have friends. And a lot of us had CB radios in our
[00:00:51] cars and our trucks. And we would drive around the mall or the Walmart or whatever and talk on
[00:00:56] our CBs and pick up girls. It's a lot of fun. At least it seemed fun then. It was a tremendous waste
[00:01:02] of time. But talking on the CB has been a passion of mine almost 45 years now. And it's had held
[00:01:12] greater passions at different times, a greater depth of passion for me personally over the
[00:01:17] years. But it's always been a fun hobby that I've had. It actually is what got me into
[00:01:23] working for Radio Shack. It got me into being on the FM radio dial. It got me into
[00:01:30] amateur radio and we'll see what it can get you into. One thing, it can get you out of trouble
[00:01:35] if you're in a mess. Now, it can get you into trouble too. I won't, you know, if you're doing
[00:01:40] things the wrong way and get caught then it's going to get you in a mess. But if you're
[00:01:44] stuck on the side of the road or you're trying to figure out where the local restaurants are
[00:01:48] on the interstate, you may, and I say that with extreme caution, you may be able to get some help
[00:01:54] on the road with a CB radio. And if you're a prepper, it might even help you establish a
[00:02:01] communications plan and a setup within your group or your family or your farm or your bug out
[00:02:06] location or whatever. It's a great tool. It's called CB radio and it's been around for a
[00:02:11] very long time here in the US. Hub City, Mercantile is mine and my wife, Carla's business. We sell
[00:02:20] Berkey and British Birkfeld replacement filters. We sell the British Birkfeld brand of filters,
[00:02:26] the Gravity Water filter systems. That's the one all the others are copied after. Like it's
[00:02:31] the original. Everyone else is a clone. And you know I hate to give the British credit for
[00:02:36] that. You know our cousins that we beat almost, well we beat them back across the ocean is what
[00:02:42] we did in 1776. So anyway it's a business that my wife and I have here in our salon and boutique
[00:02:51] in the upstate of South Carolina. We do sell water filter systems, replacement filters and
[00:02:56] whatnot and we'd like to help you with your needs. Hubcity, mercantile.com there'll be a
[00:03:01] link in the show notes as always. I'm Caleb Nelson, K4 CD and I've already told you that.
[00:03:07] And we're continuing our talk here about Citizens Band or CB radios way back in the day as I
[00:03:13] mentioned. These things are so popular and if you were cool you had one. And if you wanted
[00:03:19] to be cool you wanted a CB radio because everybody had one. There were movies and
[00:03:23] television programs made specifically around the CB radio. Oh my gosh there were so many cool
[00:03:30] CB movies back in the day. It operates in a frequency band known as the 11 meter band and
[00:03:37] the frequencies are specifically between 26.965 and 27.405 megahertz. The 11 meter band it used to
[00:03:48] belong to the amateur radio guys and back in the late 50s they gave that band to the citizenry.
[00:03:56] They opened it up first as a license to where you paid to basically have a little ticket that
[00:04:01] you could use to legally talk on the radio. And it made it very accessible because the technology
[00:04:07] was there and the market was flooded and you could buy brands from Kmart that were their own brand
[00:04:14] all the way up to Cobra and Johnson and all these browning you've heard before. I bought
[00:04:21] a tram CB radio a couple of weeks ago and sold it at the same. Within five minutes I wish I
[00:04:25] had kept it now. One of the most beautiful radios I've ever seen. I know there's some guys
[00:04:29] grimacing when I say that I need to get a picture so that I can show it to you guys. It was a
[00:04:34] beautiful beautiful radio. I may just go buy it again. Just pay for what I sold it for.
[00:04:39] I wonder if Brett's listening. N9LPT if you're listening to this program I want to buy the
[00:04:43] CB radio okay. 11 meters is in HF. It's part of the shortwave end of the spectrum
[00:04:52] and that means that these these signals can travel longer distances sometimes not every time. They
[00:05:01] can travel a lot further with illegal power amplifiers but usually the conditions don't
[00:05:06] favor extremely long distance communications for these particular frequencies. You can
[00:05:12] realistically expect the CB radio to operate up to about 15 miles just depending on your terrain
[00:05:18] and where you find yourself what's between you and the person you're trying to talk to. I mean
[00:05:22] that literally like is there a massive city full of all kind of radio frequency interference
[00:05:29] and tall buildings maybe there's a huge mountain between you and your grandma
[00:05:34] and that may not be the best thing to try to use but could also work pretty well just
[00:05:38] depending on what uncle's son, uncle's old soul the son is doing to the atmosphere.
[00:05:45] For the vast majority of CBs that you'll find made prior to the last five or six years they come with
[00:05:52] two flavors AM or AM and single sideband. We've talked about single sideband numerous times
[00:05:58] real quick AM is called amplitude modulation and this has just been the default of CB radios
[00:06:05] from day one and it modulates the amplitude of the radio wave carrying the audio signal.
[00:06:11] Unfortunately AM is very susceptible to interference from all kind of devices
[00:06:18] and you know five to ten miles is about the best you're going to do right so single sideband is
[00:06:24] the other and again I said the last time through if you're serious if you're very serious about
[00:06:31] CB radio communications in your prepper plan you should have a single sideband capable
[00:06:38] CB radio in your toolbox because it's going to give you 50 to 100 percent more range
[00:06:44] you get a little bit more power but at the same time the way that it breaks the signal down
[00:06:48] you're going to get a lot more range. Now I say a lot guys I'm not talking you know 300 miles
[00:06:55] versus 15 maybe 100 maybe and again it depends on your antenna every time and then what else
[00:07:02] you've toys you've put in there that we're not going to talk about. The only problem with a single
[00:07:08] sideband radio is if you have one and your own single sideband upper sideband channel 39
[00:07:15] and your buddy's got a regular old CB on channel 39 you're going to sound like Charlie Brown
[00:07:21] school teacher to your buddy he's not going to be able to decode the radio can't decode the
[00:07:25] single sideband because it's AM only but with that said if you if you're going to have
[00:07:31] CB's in your preparedness plan and you know let's say you've got 12 people you're trying to do
[00:07:37] make a plan you know in this plan maybe two or three get single sidebands set them up as base
[00:07:42] stations in their house everybody can have a low cost regular old AM FM CB in their car the
[00:07:48] little radio oddity is amazing I keep beating that drum guys it's a very very good little
[00:07:54] radio and it's it's the size of half the size of a paperback book so there'll be a link in
[00:07:59] the show notes for that one the thing about it is if you're going to set it up in your house you
[00:08:04] should really consider spending the money for a large and well-made external antenna now you can
[00:08:10] make them cheap and they'll work fantastically but you can buy buy one that's you know weatherproof
[00:08:16] and ready to go permanently mounted outside and stay out there hundred bucks or so and
[00:08:22] there'll be links for all this stuff in the show notes as well that makes the biggest
[00:08:26] difference you got to have cable to go between the radio and the antennas called coax you don't
[00:08:31] have to spend a lot of money on that coax now when we get into higher frequencies we'll explain the
[00:08:35] difference there but you can really get in with the low cost coaxial cable for CB radios and it's
[00:08:41] not going to bother you CB radios man 15 miles max sometimes just depending on what's going on
[00:08:47] around you maybe just one to two miles you can use up to 12 watts in single sideband
[00:08:54] you've got four watts on am that's the output power it's really it's really all about the antenna
[00:09:02] and having the antenna properly tuned properly grounded and working so that it can be at its
[00:09:10] best performance state for your signal and I know you guys are like would you just please tell
[00:09:15] us what to buy I'm trying to help you understand that why you have to buy stuff I get that
[00:09:22] if you don't have it you have to buy it and you are interested in knowing what to buy
[00:09:26] but at the same time you got to know why like I may say you need to buy this $120 antenna and you're
[00:09:32] thinking well man I can get on Amazon there's an antenna for $12 but if it's not operating at its
[00:09:39] peak efficiency you're already behind you know the behind the black ball when you're trying
[00:09:44] to operate a CB with its low power output on this particular range of frequencies sometimes
[00:09:50] you got to spend and that may lead you to building your own antenna which they work really well
[00:09:54] if you'll just follow the instructions they work really really well so yes you do need to buy stuff
[00:10:02] especially if you're wanting to add CB radios to your prepper toolbox now let me just go through
[00:10:09] a couple of things I love this little radio oddity it'll be in the show notes number one
[00:10:13] choice back in the day I was a huge cobra radio user I had the cobra 25 lttd classic I had a 21 lttd
[00:10:22] I had a 29 lttd 146 gtl I had a lot of these different things and that's just like well is he
[00:10:28] speaking Chinese no those are model numbers from cobra radios they were a really good quality
[00:10:34] back in the day well built not necessarily industrial grade stuff but they were everybody
[00:10:41] had one they all worked well it sounded fantastic even with the stock microphone
[00:10:46] stock power output they were great radios and lasted for forever what happened was I kind of got
[00:10:53] not so in the CB and more into big subwoofers and amplifiers but I didn't want to give up my CB
[00:11:00] radio communications potential so I downsized from the cobra 25 lttd classic or one of its
[00:11:08] variants down to a unit in 510 pro or the unit in 520 pro I've had them both I've still got a couple
[00:11:15] of those matter of fact I like to buy them when I find them cheap at Hamfest and whatnot because
[00:11:19] they just work they're very small footprint they're a little bit bigger than the radio oddity
[00:11:25] and they're a little bit smaller than the big cobra so they'll still go into modern day vehicles
[00:11:30] pretty easily they come with this real tiny microphone which works well and guys I'm telling
[00:11:35] you 30 years later they still work and they work very very well so they don't take up a lot of
[00:11:41] space in your car but they may perform a little better than the small the real tiny ones that are
[00:11:46] out now from China so again the radio oddity great success cobra unit in and then if you want
[00:11:56] something larger it's really hard to be the galaxy or a president those are brands galaxy brand and
[00:12:03] the president brand the presidents are cool because they have they're all named after former
[00:12:07] presidents of the united states which is crazy I love the idea and and they're on the internet you
[00:12:12] can find them I'll link some of my favorites in the show notes and then galaxy radios are just
[00:12:17] fantastic right before I got my amateur radio license I finally bought me what's called it
[00:12:23] like a trucker cb is a galaxy 959 dx and man that was a that was a talking radio love
[00:12:30] that thing and then like six weeks later I got my amateur license and really haven't used it in the
[00:12:34] last 15 years but that to say they still make them they make great products and I would encourage you
[00:12:41] if you're willing to spend it's really hard to beat a galaxy or a president and there's other
[00:12:46] brands out there too striker and then you've got radio oddity any tone I think is doing cbs
[00:12:52] I'll link some stuff in the show notes and you just have to decide one it's all really
[00:12:56] we've talked about this before how much do you want to spend how far do you want to talk
[00:13:01] and how bad does the person on the other end want to talk back to you so again if you're looking for
[00:13:07] just a low-cost entry you got the unit in 510 520s you've got the radio oddities and maybe one or
[00:13:14] two little any tones if you want to spend some more money you've got the cobras the galaxies
[00:13:19] and the presidents and that's really kind of where I would stop now if you're going to
[00:13:24] utilize the any of these radios in your car they connect to the battery now I don't suggest taking
[00:13:31] the larger radios to your cigarette lighter plug but I know you're going to do it anyway okay I
[00:13:36] know you're going to it's just the best practice to go all the way to the battery if you can't
[00:13:41] go all the way the battery you can take your radio or take your car to a local electronic shop
[00:13:46] and they can run the wire through the firewall for you a lot of people do that it's pretty
[00:13:49] inexpensively if you don't want to go that far at least go back to the fuse block okay keep it out
[00:13:55] of your cigarette lighter because that's going to be in the way of charging your phone let's just be
[00:13:58] honest okay if you're going to use it at home then you need a power supply and this is what this
[00:14:04] is a box that you plug into your wall and it takes that type of electricity and turns it into
[00:14:10] the type of electricity that your cb radio needs to operate that's 12 volts dc and these can be
[00:14:18] found anywhere from $29 or even less up to hundreds of dollars I'll put some links in the show notes
[00:14:26] that can do cb radio and if you decide you want to add more as we go through the process
[00:14:32] there'll be growth there with its capabilities so you don't have to do this two or three times
[00:14:37] there's one I really love it's about between $79 and $99 I have a couple of them all over
[00:14:42] I've got radios everywhere and you have to power them so I've got I've got this stuff
[00:14:46] everywhere but they work well they're very quiet so they're not going to make a bunch of noise
[00:14:51] when you're operating or whatnot and they just do what they're supposed to do
[00:14:56] so it doesn't take a lot to have a cb it doesn't take a lot of money to get started
[00:15:02] again you can you can buy a small one for your car get a little antenna put it on the roof
[00:15:07] you'll be shocked and if you put the radio on channel 19 and you go down the interstate
[00:15:11] you'll probably be really shocked I gotta I should have said this very firstly but cb radio nowadays
[00:15:19] is rated r most everywhere it doesn't mean it's all bad all the time but it's a cross section of
[00:15:26] humanity and I mean you can get on youtube and watch music videos and you can see there's
[00:15:30] some really great stuff and there's some garbage in that's just like that with everything
[00:15:34] including cb radio so don't get on the highway you know you got your kids in their car
[00:15:40] seats in the back and you turn on channel 19 you're going to talk to truckers all the way to
[00:15:44] grandma's house your kids are going to learn some words you may not want them to know so just be
[00:15:48] cautious with that kind of stuff guys even in your home be aware but that's not to deter you
[00:15:54] I mean it's a great tool for preppers it's pretty cheap comparatively speaking to everything
[00:16:00] else out there and if things ever go sideways you've got a great way to communicate and it's
[00:16:06] also a way that you can start at the bottom end of things with your proper group or your friends
[00:16:13] or whomever you're planning to hopefully talk to base stations are a lot of fun I would encourage
[00:16:18] a larger radio for that most especially if you're serious I would do a single sideband radio again
[00:16:24] you can get those from unit in galaxy cobra president there's a selection of sideband radios
[00:16:32] with different features and you're just going to defend decide what you're gonna you know how much
[00:16:37] you will in the spend if it were me I would definitely if I was serious and I was kind of the
[00:16:42] the center of attention or the place everyone wanted to speak to or I wanted to speak to
[00:16:47] everybody I would invest in an external antenna I would mount it up as high as I can get it
[00:16:52] back in the day they used to put them in trees they would mount it to a mast and then attach
[00:16:57] the mast up into a tree as the crew it's a great idea actually you could spray paint the outside
[00:17:02] with a gray or a green or even a brown and it goes up in the tree it's kind of camouflaged even in
[00:17:09] the fall the winter and you can get some height that way I mean you can get creative man YouTube
[00:17:14] is full of people telling you how to do all this stuff that's not where we're going with this
[00:17:19] program I'm just trying to help you make good decisions as you're trying to figure out what's
[00:17:23] going to work best for you so you need a really good antenna there's CB radio operators everywhere
[00:17:30] and you can probably find someone that can help if you have questions and of course we're here
[00:17:34] to help if you need some help but we're not local to most people so try to make some friends
[00:17:38] and know that not everybody is going to like you because you have a CB but understand that
[00:17:42] not everybody talks on the CB radios and it's okay it's a great tool if you're a prepper
[00:17:47] and you're looking for a great tool CB radio is it this these show notes for this particular program
[00:17:53] will be more link oriented to get you you know pointed in the right direction for gear it's really
[00:18:01] simple as buying a radio buying the cable to go between the radio and the antenna and buying an
[00:18:07] antenna and then how do how you're going to power it if you're looking at mobile installations
[00:18:11] most of those antennas come with the cable attached to it if you're setting up a base
[00:18:16] station you'll have to have the cable to go between the radio and the antenna give yourself
[00:18:20] an extra 10 or 15 feet or a little more if you need it when you when you decide how much you're
[00:18:26] measuring out to purchase to feed the antenna with the power supplies will be in the show notes as
[00:18:31] well again this allows you to operate the 12 volt radio that can work in your car it allows
[00:18:38] you to power it from the inside of your home this is not hard stuff the the ebook will be
[00:18:44] linked in the show notes it goes to a lot of these things a lot of this stuff is common sense and
[00:18:49] guys you know as well as I do that's why your podcast listener that youtube has the answers to
[00:18:54] virtually everything but if you stumble into something and you just can't figure it out please
[00:18:59] don't ever hesitate to contact us and we'll do our best to get you squared away or at
[00:19:03] least pointed in the right direction now this is not going to finish out our talk on CB radios
[00:19:08] we'll probably come back one more time but I hope this has been some understanding for you and
[00:19:14] some help I mean it's not hard communications is not hard it's just it doesn't like fit in everybody's
[00:19:23] understanding but it still doesn't mean that it's hard and that's the purpose of this program
[00:19:28] to help you make good decisions not in fear so that you can move forward in your communications
[00:19:33] plans and strategies in case something were to happen because you're prepping for something right
[00:19:38] we all are whether we realize it or not okay I'm going to go where you we can be found online at
[00:19:43] prep comms.com of course hub city mercantile is our show sponsor hub city mercantile.com that'll
[00:19:50] be in the show notes we appreciate your business by the way always love it when you guys review
[00:19:54] the program share the show and check us out on youtube now there's no like real videos there
[00:20:00] it's just this but some people like to listen through youtube of course we're on spotify and the
[00:20:05] apple thing too so we're everywhere and thanks to you we're continuing to grow the program
[00:20:10] we'll be back next time we're going to be finishing up cbs then but until that moment in time
[00:20:16] guys have a great day thank you again for listening god bless you 73 y'all
