The Yaesu FT-1500M will go down in history as yet another landmark in radio engineering and further enhances Yaesu's legendary reputation for tough durable construction and precedent setting design. Yaesu's FT-1500M, a masterpiece of RF and mechanical engineering, is a trendsetting blend of compactness and functionality. The Yaesu FT-1500M is the most quiet and efficient radio transceiver ever built. Excellent receiver performance, direct keypad frequency entry, Alpha-Numeric Memory System, and 50 Watts of output power, and DB-9 data port are just the start! Greater operating Efficiency Yaesu's FT-1500M represents a technological breakthrough in radio transceiver design! New advances in power amplifier technology combine to provide you with 50 Watts of clean transmit power with enhanced current consumption efficiency. Yaesu's patent pending aluminum die-cast shell construction dissipates heat throughout the entire transceiver chassis and eliminates the need for an external thermally switched cooling fan. This allows the FT-1500M to fit in an incredibly small case size: less than 5 inches square X 1.4 inches high (weighing a mere 960 grams) and offer superior operating specifications as well! Better Receiver Performance The FT-1500M's receiver section is as tough as its construction. It features Yaesu's renowned RF ATT (Advanced Track Tuning), that allows for outstanding spurious image rejection. The automatic tracking bandpass filter used in the ATT system protects the RF receiver section from strong out-ofband signals that can result in intermodulation and adjacent band interference in lesser quality transceivers! The FT-1500M's wide band receiver covers 137 to 174 MHz. The FT-1500M can monitor Amateur, Public Safety, and Weather Band stations with ease, keeping you in touch with all the action in your community! Easy Data Interfacing For packet operation at either 1200 bps or 9600 bps, The FT-1500M is conveniently equipped with a DB-9 data jack located on the rear chassis for neat and organized data interfacing. The DATA jack provides connection points for transmit data, receiver audio, PTT, and ground. Signal levels, bandwidths, and impedance levels are all optimized for the user selected data rate for maximum throughput.
