The Ranger RCI2970N4 is a 400w ham radio transceiver designed for 10 and 12 meter band communication. It is not an 11 meter (Citizens Band) radio, but users will often convert one channel to that band. With sideband capability for USB, LSB, and CW modes, this dual band radio offers versatile and reliable communication for amateur radio enthusiasts. Made by Ranger, a trusted brand in radio communication, this ham radio meets the needs of those looking for high-performance ham radio equipment. Ideal for those looking to expand their radio communication capabilities, the Ranger RCI2970N4 is a top choice for hobbyists and professionals alike. 10 & 12 Meter Mobile Amateur Radio.

Mounting Bracket with Hardware. 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.
