Note, this is an upgrade to the AT-5555N. The main difference with this newer version is RX Noise Reduction (NRC). The newer version includes an extra PCB inside the radio specifically for a receive noise reduction function. This feature helps to reduce background noise on incoming signals. 50 Watts PeP (Bird), 30 Watts RMS (Dosy). Large LCD panel that can display much more than just the frequency. Backlight uses EL technology. Includes CTCSS / DCS module. Extremely Stable on SSB. Echo / Reverb & Talkback. Multiple Clarifier Operating Modes. RX compander: noise blanker. Noise gate setting: mic noise adjustable. Compatible with electronic and dynamic mics. SWR? S/RF? DC Voltage display function. Power Supply Voltage Protection. Frequency Range 25.615 – 30.105 MHz (AT-5555EX version only). Antenna Connector UHF SO239. Temperature Range -15/+50 °C. Input Voltage 13.8V (15.9V max / 11.7V min) – 9A max at 40W SSB PEP. Radio is fully PC programmable (with optional PC Interface Cable). Dimensions: 28cm x 25cm x 6cm; 11in x 9.9in x 2.4in. Weight: 2.8kg; 6.2lbs. 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.
