Description
At a palm-sized 4'' x 4'' x1'' body, this radio is easy to mount on any vehicle. The handheld mic comes with a large 7-color adjustable backlit LCD display and built-in speaker. You can use it in America and most European countries, allowing you to listen to more stations. Press and hold the PTT button, then short press the “EMG” key to activate the VOX function. After that, you can free yourself from finding the microphone and the PTT button to make it convenient and safe to use your CB radio while driving. An ideal radio for emergency communications or for traveler assistance. Priority should be given to calls for help if you use this channel. Press and hold “CH ↓” or “CH ↑” for 7 seconds to start the scan function. This allows you to find and listen to active channels quickly and easily. This allows you to adjust the receiving sensitivity between 3dB and 48dB. Normally, it should be set as high as possible to receive stations far away. Nine (9) Automatic Squelch (ASQ) for FM and 34 Manual Squelch for AM helps this radio block out background static and noise when receiving.

Outstanding CB Radio. Better than Cobra or Midland Hand Held
This is an excellent radio. I used it to replace a Cobra 75 that I damaged when removing from my previous car. This radio is half the price. The microphone is much smaller than the Cobra as is the transmitter box. On the road, people comment they can hear me clearly on AM due to it having a condenser microphone. It also has FM which the Cobra does not. Proper installation is essential, or the radio is worthless. The following is a guide to installing this thing in an SUV, which is the hardest type of vehicle to put this kind of radio into properly. THE PROBLEM: Antenna location on an SUV is the biggest problem. You want the metal of the car to act as a ground plane which means it should be below the antenna not along side of it. You want the antenna to be as long as possible, but you also have to put your car in a garage, either at home or places you drive to. That rules out a magnetic mount roof antenna. THE SOLUTION: I'll describe what I did and provide an Amazon parts list via links. CB RADIO: The radio I picked was the Radioddity CS-47 Small CB Radio, AM/FM, 40-Channel, One Hander. It is tiny, not much bigger than a pack of cigarettes. You can hide the radio inside the center console with room to spare, which is also where you plug it in because there is a cigarette lighter jack there. Then, the only thing you see is the microphone itself but you can hide that too. https://www.amazon.com/dp/B0BQJ8Y5B7 There is another version with the controls on the box which is cheaper. https://www.amazon.com/Radioddity-CB-27-40-Channel-FM-Emergency/dp/B0B56KST6F ANTENNA: The only realistic location for a CB antenna on a Highlander is a fender mount close to the windshield. I used a 2 Foot Firestik II FS Series Tunable Tip CB Antenna. This length is perfect because you can still get the car into a garage and it transmits reasonably well. You can also use an antenna spring (optional). https://www.amazon.com/Firestik-FS-2BK-feet-Tunable-Antenna/dp/B004USX7EE/ref=sr_1_1 CABLE: For the cable, you MUST Use the Firestik FireRing CB Coax with Stud. Do not modify this cable in any way. After you bring the cable into the car, do not coil the excess because that would make an inductor out of it. Just shove it under the floor mat in a random arrangement. If you do not do this you will detune the antenna and it will work poorly. Protect the cable with wire loom all the way to the antenna. https://www.amazon.com/FireStick-FIRESTIK-K4-8R9-Antenna-FIRE-Ring/dp/B01D09WIL6/ref=sr_1_1 MOUNTING: I used the Firestik SS-174 Hood Channel Mount Tall w/K-4 Stud. This requires some modification. You may need to cut off the short right angle part of the bracket after the slots. Using a vise and hammer, bend and reshape the bracket so that it looks as shown in the pictures below. If you do it right, the bracket will slip through the slot between the hood and the fender and won't even touch the paint. https://www.amazon.com/Firestik-SS-174-Stainless-Steel-Channel/dp/B000X3D7PE/ref=sr_1_1 SWR METER: You absolutely positively need to buy this or you are otherwise wasting your time. The antenna must be exactly tuned to match your radio. Otherwise, there are standing waves. This means that the power from the radio gets sent to the antenna and then is reflected back to the radio instead of going out over the air. The antenna is tuned by adjusting a bolt on top of the antenna in very small increments until you get the minimum SWR. Even 1/8 of a turn is significant. The bolt is hidden by a red cap. Tip: The red cap affects the SWR reading by quite a lot. Take it off to adjust the screw, then put it back on before you make each SWR measurement. https://www.amazon.com/Astatic-PDC1-100-Watt-Meter/dp/B004ULN610/ref=sr_1_3 INSTALLATION: The pictures show details of the installation. On the passenger side of the car you need to locate some painted steel inside the hood you can attach a mount to. Spend some time hammering the mount to the right shape for your car. You should be able to attach it perfectly so that when the hood closes it doesn't touch the bracket and the bracket doesn't touch the fender. . The cable then goes along the top inside of the fender where you can easily bring it out at the door hinge. Route the wire as shown so it goes inside the passenger compartment and then down to the floor underneath the floor mat. Randomly arrange the excess wire under the floor mat but do not coil it. That would make it an inductor and mess up the antenna matching. From there, route the antenna cable underneath the passenger seat. Move the seat all the way forward so you can drill a hole in the side of the center compartment about 5 in above the floor height. Now the antenna connector is inside the compartment. You can mount the radio using some Velcro. Many cars have a cigarette lighter outlet in the center compartment. If so, just plug it in there. Finished! I think the pictures are pretty much self-explanatory. Oh, you'll also need a CB handle. Nobody uses their name. Something like Happy Rabbit or whatever suits you. 10-4.

Excellent, compact CB with good sound. Highly recommended.
I'm very happy with this CB radio and recommend it. Here's why: Very compact base unit may be the smallest one out there. Radio and mic are sturdy. Can be quickly moved from one vehicle to another. AM/FM (I wouldn't buy a new CB radio without FM). Channel scan (spends about 1 second on each channel looking for activity, also a feature I think is mandatory). The mic/speaker are both built into the mic unit and the sound is good and surprisingly loud. The mic is not too large, and the brightness of the display is perfect for day/night use. Not necessary to permanently install the radio. Can just plug it into the 12-volt socket on most vehicles and set the mic inside a cup holder. Nice customizing ability in the menus for various options. Also has VOX (voice activated mic) that can be enabled. The center button the top of the mic serves as a "mute" button which is nice to be able to quickly mute the radio without turning it off. This radio has the codes feature which if used with a second CB (that also has this feature) will make it so that your radio ignores any other conversations. It doesn't prevent other people from hearing your conversations, it just prevents you from hearing other people's conversations. Everything is controlled through buttons but I'm okay with that. Yes, I like the old school chrome radios with all the switches and knobs but having everything built into the mic is better plus most of those older style units don't have channel scan and without that feature you're going to be endlessly turning the channel know looking for activity. Here's how I mounted mine. I sat the base unit vertically on the floor of my car next to the console. I attached a piece of industrial Velcro to the radio's bracket and the other Velcro to the console. While you don't have to use the bracket, I chose to use it to provide a bit of a small air gap for ventilation purposes and so I wouldn't lose the bracket as I moved the unit from car to car. You could just Velcro this lightweight base unit anywhere you want. The side of the base with the circle is where you want to apply the Velcro as the other side (no circle) gets slightly warm during use. While you don't have to install the metal mic clip, I chose to do that to put the mic exactly where I wanted to on my dashboard to keep it within easy reach and to see the display easily. You can just set the mic in a cup holder. One other tip, buy a three-foot long antenna to get some reasonable broadcast range of a few miles. The short antennas always reduce the broadcast range of any CB radio. If you're traveling in a convoy of vehicles close together it wouldn't matter as much, and a small antenna would work.

Universally recommended best value
I universally recommend this radio as having almost every feature (except weather radio and SSB). Most importantly is the DNR noise reduction that is so effective. Expandable, and has good audio level from the handheld speaker mic on receive and transmit. Very compact size, I have used this in several vehicles. Clear transmit and receive audio. Good simple radio for friends and family. Also good radio for enthusiast to travel with for rental cars or for convoy etc.

Nice, Compact, Works Great 👍🏻
Works like a charm. Got it mounted inside the center arm rest box. It brings in skip like crazy! But, that's also a little help from the antenna!! Decent sound quality, mic controls are OK. I'm happy with this little radio. Out of the way, got it if needed! And, if you need to move it to various vehicles, very simple.... It has a cigar lighter plug for power, and you attach the antenna coax, done! On-the-air!

An overall decent simple all in one CB with some drawbacks
First, unlike others who received this item for free, I purchased it which in my opinion limits the bias in reviews. That being said, I was looking for a simple CB radio mostly for my state to state travel when I am stuck in traffic on smaller highways and either do not have cell reception or the maps are useless as they do not have up to date info. I am an amateur operator but don't bring my equipment to be put at risk on travel. I did not want to have a large radio or even deal with mounting the rig if I chose not to. I was surprised to come accross this Radoddity CS-47 CB which appeared to be a good value for $99 and would meet my needs for communication in desolate areas. I bought the unit and upon unpacking, confirmed my amazement for such a small unit but it also had a good build quality as well. I did initial testing at the "base station" and had no issues making a contact many states away which a great sounding radio report was given. The mic is very functional, simple, and most importantly, small but has all the controls. I saw a video on the various settings and such and customized the color display. I ran some tests against my other radios and found that the tonal quality on both transmit and receive was very good. I tried the various DSP modes and set it on "3" which provides a large noise reduction but still allows for a decent sound on receive. I tried the transmit "noise reduction" as well but did not feel like it was too effective however I set it at "2." The controls are layed out well and in one hand I can change volume, channels and even modes if I care to employ FM. I still have yet to find an FM operator to talk with on the CB bands here in the US, but maybe it has more support elsewhere. In testing FM listening with my amateur equipment it sounded great of course. The various roger beeps are great too. I paired this with a Lil Wilson magnetic mount antenna but the range is not far via ground wave (maybe 2-3 miles) so I am upgrading the mobile antenna with something larger. One complaint I have is about no SWR (even a warning) so you have to use a meter to check. The other is no SSB which I knew going in to this. I think that this rig is fine for the most part with AM/FM but it would be nice to see another model with SSB. There are other rigs like Anytone that offer SSB and more but those are much more than $99, however Radioddity should have an SSB offering to compeat in the next segment up as this is a nice quality radio and a great value for AM CB communication when traveling like I do.

Excellent compact CB radio.
I waited for a while to write this review as I just got done installing this very compact CB radio, it took me some time to figure out where I wanted to mount it, I have it hooked up to a Hustler HQ27 mounted on a front fender channel mount, I am impressed with how well this radio works as I was heard around 5 miles out, the sound quality on the receiving end was loud and clear, the only speaker which is the small speaker in the mic or handset sounded way much better than I had expected, I definitely recommend this radio for small vehicles and the main unit could be easily hidden or concealed, I have a few items on order such as a panel mount RJ45 and 3 meter mic extension cable so I can mount the main unit hidden and extend the mic cable.

Love It
I am a driver and had no interest in a cb because I keep mine turned off most of the time in my rig and get tired of hearing the carbage on a cb and the white noise.....but this is so cool I had to reconsider the idea for my personal vehicle. I paired it with a 4ft firestick, have my mount grounded good and got my swr's low and the clarity is better then any cb I've ever owned. I've ran cobra for over 27 years behind the wheel and never have been excited to hear the chatter until installing this one. I have received and transmitted over 10 miles with obstruction and that's good! There's just a one con....1. While scanning all channels the hand held locks out functions such as volume or squelch. You have to stop scanning to adjust anything. Other then that it's great. I plan to install a flush mount usb port that plugs directly to the transceiver and the mic to the flush mount for a remote set up that matches my gmrs radio. Small, compact, great audio and packed with features. Definitely one to consider.

GREAT little CB ...make sure you use the Noise Reduction Technology
I recommend this to hundreds of people on many CB forums.... just because I watch the You-Tube Videos and read what this radio can do...and think it looks fantastic! after telling so many people what a great radio it was. My girlfriend got me one.... I didn't use it for 6 or 7 months... when I did take it out of the box to use it, it didn't work???? I contacted Radioddity..... they we very friendly and always answered my e-mails... but needed proof of purchase... my crazy girlfriend was long gone by then ( thank heavens) so I don't know where she got it and had no paper work.... I ALWAYS register anything I buy and did not see the registration card in the box so I figured I registered it when I got it. I told Radioddity to just look me up?? they said I wasn't registered???? and they needed my order number??? if not the order # from them.... than the Amazon order #??? after going back and forth it was hopeless, I didn't have proof as it was a gift. that doesn't make me too happy... but I should have tried it when I first got it so let that be a lesson to me. I did like it and I bought another one myself from here.... GUESS WHAT... no warranty card in the box to mail in.... I guess they don't do that... they look it up by your order number! I like the little CB... the menu on the mic takes some getting use to and I'm not crazy about the Squelch being a menu item... but I guess I would get used to it.... I mostly bought it to do some youtube range tests with it and to loan it out to friends that are thinking of getting a CB that don't have much room in their vehicle. I hooked it up to my very tall 50 foot base station and talked to the 5 or 6 people in my 30 mile area that I always talk to... it transmitted and received just fine.... BUT all the people I was talking to told me I sounded distant??? they were all saying to hold the mic closer to my mouth.... I have been into CB for 40 years I know how to talk into a microphone!!! so I had to go into the settings and turn up the mic gain to max.... it didn't help... I have a VERY loud BOOMING voice so my voice has always done fantastic on any radio.... but not this one..... everyone could hear me and talk to me... but they all just kept saying it was like I was several feet from the mic and was very distant???? I couldn't adjust it any better... but it's still a great little radio for the price.... I'm not going to knock it!!! for the cheap money and all it can do .... its really something..... and it has the Noise Reduction Tecnology that makes a CB a total GAME CHANGER!!!! any radio without the ( NR ) Noise Reduction technology is like a model T car compared to a new Corvette!... it is truly like day VS night..... don't ever buy a CB without it!!!!!!...... this little radio is truly amazing!!!!! for the people that don't know what NR is..... there is always noise in the background on CB.... if someone doesn't have much power ( watts) or a cheap antenna they may only transmit for 3 or 4 miles... and that background noise will be louder then the signal they are putting out... so you will not be able to hear them as the noise is louder than they are.... but turning on the NR technology gets rid of most of the background noise... I recommend setting it to # 2 or #3 .... once it's on the back ground noise will be much less and you will be able to hear someone very far away that you normally would not be able to hear. I have a side band radio SSB ( NOT THIS RADIO I have a Radioddity QT60) and I talk to people all across the USA in every state! and in many other countries from South Africa to Jamacia to the UK and Scotland.... using the NR Technology I can just barely hear the people I am talking too.... but I can hear them and they can hear me and we can talk..... without the NR all I would hear would be noise and static!!!! so for a radio under a $100 dollars this is amazing!!!
