This is a 10‑meter amateur radio. It is not a 40‑channel CB radio and will not operate on CB channels unless properly converted.
The Connex 3300 is a long‑time favorite among truck drivers who want loud, clean audio and simple, reliable controls. This radio is built for real‑world trucking — noisy cabs, long nights, rough roads, and unpredictable weather. It is easily convertible from the 10 meter band used by licensed ham operators to the 11 meter (Citizens) band used by truckers, but it is unlawful do convert pre-sale. You can find YouTube videos on how to DIY this, or you can pay a radio shop to do it.

How to Convert the Connex 3300 to 11 Meters
The Connex 3300 has a row of 15 pins on the front panel.
To convert from 10m to CB, youunsolder a short jumper wirefrom the7th pinto pins 11 and 12, andremove the solder bridgebetween pins 11 and 12 so they are independentCB Tricks.
This changes the radio’s tuning so it now covers the CB range (26.965–27.405 MHz) instead of ham bandsHam Radio Transceiver.
- The process is straightforward and does not require “peak and tune” by a technician — the radio is already peaked and tunedHam Radio Transceiver.
What You Need to Do the ConversionA soldering iron and basic electronics skills. If you do not have those skills, you can hire high school a kid or community college electronics student to do this for $20 cash ( contact the school). Or you can watch a YouTube video on soldering basics for electronics.The Technical Jargon Version of the Features:
- 40+ Watts

- AM/FM/PA
- Rear Frequency Counter Jack
- Vol, Sql, Mic Gain, RF Gain

Important (already said a different way, but we need to be clear)
This is a 10 meter, not 11 meter, radio. That means it does not operate on the Citizen's Band (CB). However, all 10 meter radios are built with easy conversion in mind (see above for how to convert this particular model).
The single largest market for 10 meter radios? Truckers who need distance, and that means they need more than the 4 watts permitted for CBs. So they buy a 10 meter radio and convert it. You do not need to pay someone to "peak and tune" the radio, it already comes peaked and tuned. Just not converted.
3300HP vs 3400HP vs CX: Feature Differences That Actually MatterConnex 3300HP
Connex 3400HP
Connex CX3400HP
Highest published output (50+W)
7‑color selectable backlight
More controls on front panel
Larger chassis and meter
Best for buyers wanting the most feature‑rich, highest‑power Connex in this family
🧠 What This Reveals (the part Connex never explains)
3300HP and 3400HP are closer than their names suggest — the 3400HP is essentially a modernized 3300 with color options and a different meter.
CX3400HP is the “premium” variant, with the highest output and the most front‑panel features.
The taxonomy is meaningless — “33,” “3300,” “3400,” “CX,” and “HP” do not map to a coherent hierarchy. So don't be confused if you can't follow the logic. It's not you, it's them. They are good at making radios, bad at naming them.
FAQs
"Is this a CB?"No, it is a 10 meter radio. The Citizens Band is limited to 4 watts and operates on the 11 meter band per FCC regulations. Truckers and other long-range radio users buy a 10 meter radio and convert it to 11 meters. 10 meter radios are designed and built with this in mind, but are not sold converted because FCC prohibits that. If you see "10 meter radio" on a listing, it is not a CB.
"Is it peaked and tuned?"All ham radios are "peaked" by the qualified engineers who design them. A radio hack without an engineering degree and radio design experience cannot improve on this, though they can alter the radio for higher output wattage. But this overdrives the transistors, causing distortion and overheating. Not a good thing to do. All imported radios are tuned to their respective bands, per FCC regulations and Customs enforcement. There is no additional tuning required."Why the ALL CAPS for mosfet?"Because MOSFET is an acronym, and in English acronyms are spelled in all caps. MOSFET stands for Metal Oxide Field Effect Transistor. This is not a new technology. It has evolved and improved over time. Some radio buyers obsess over what kind of transistor is used in the finals, based on something they read or their buddy told them. MOSFET isn't the only way to achieve the design engineers' goals, but this technology is often chosen.
"Is this converted?"We get this question quite a bit. It is illegal to sell a converted radio, and it also violates the TOS of any online marketplace to do so. If the listing says 10 meter and it says NEW condition, then it has not been converted. To convert it, the seller would need to open the box--therefore making it Open Box instead of New. And the title would also need to say 11 meter not 10 meter.
All of these radios are designed to be easy to convert, so there's no reason to buy one from a shady seller just because they spent 3 seconds plugging in a jumper after opening the box and then the radio case. We hope that helps you get around the confusion this issue causes.
