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. ? Built for Drivers Who Need to Be Heard. Truckers choose the Connex 3300 because it delivers. Strong, punchy transmit audio that cuts through engine and road noise. Classic Connex modulation known for loud, clear communication. Simple front-panel controls you can adjust without taking your eyes off the road. Bright channel display that’s easy to read day or night. ?? Why Truckers Trust the Connex 3300. Clear communication in loud cabs. Reliable performance on long hauls. Straightforward operation – no complicated menus. A proven radio design used by drivers for decades. Talkback for monitoring your own audio. Variable power for flexible setups. NB/ANL noise filters to reduce engine and electrical noise. Rugged build designed for daily use in trucks. ? What’s Included. Mounting bracket & hardware. 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, you. Unsolder a short jumper wire. To pins 11 and 12, and. Remove the solder bridge. Between pins 11 and 12 so they are independent. This changes the radio’s tuning so it now covers the CB range (26.965-27.405? MHz) instead of ham bands. The process is straightforward and does not require “peak and tune” by a technician – the radio is already peaked and tuned. What You Need to Do the Conversion. A soldering iron and basic electronics skills. Or you can watch a YouTube video on soldering basics for electronics. The Technical Jargon Version of the Features. Small Meter with Scales for Signal Strength and Power Output. Front Panel 4 Pin Mic Jack. Blue Lighting for Meter. Three Position Dimmer Control. Rear Frequency Counter Jack. Vol, Sql, Mic Gain, RF Gain. Dual Echo and Talk Back with On/Off/+10KHz Switch. Band Selector (6 Bands). 2 Level Power Control. ANL-NB or RB-NB-ANL or OFF Switch. What’s in the box. Radio unit, “e-chip”, microphone, mounting hardware, user manual. 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. You do not need to pay someone to “peak and tune” the radio, it already comes peaked and tuned. 3300HP vs 3400HP vs CX: Feature Differences That Actually Matter. Strong PeP output (45W). Best for buyers wanting the “classic Connex feel” without color-changing displays. Updated styling with large radial meter. Best for buyers wanting a modernized 3300 with more visual customization. Highest published output (50+W). 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. 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. 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. 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. 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. And the title would also need to say 11 meter not 10 meter. We hope that helps you get around the confusion this issue causes.
