Yaesu FT-991 HF/50 and 144/430

The FT-991 Transceiver is capable of operating SSB, CW , AM, FM Packet and System Fusion C4FM Digital.

The FT-991 is designed for the most competitive operating situations, with a suite of new features to enhance the experience. Whether you primarily operate at home, mobile or in the field, the FT-991 will provide outstanding fundamental performance and an inviting expansion into a full featured base station.

The FT-991 provides solid transmitter performance with up to 100 Watts on HF/50MHz and 50 Watts on 144/430 MHz. Recognizing an all-important Amateur Radio Golden Rule - “You cannot work them if you cannot hear them”– the FT 991 features a rugged state-of-the-art highly balanced receiver circuit configuration. The highspeed floating point DSP chip TMS320C6746 (3000 MIPS / 2250 MFLOPS) from Texas Instruments used in the receiver design guarantees excellent interference rejection with actual signals under real-world conditions, not only on HF but also in the VHF and UHF bands.

The 1st IF frequency is protected by selectable robust 3 kHz and 15 kHz roofing filters that effectively attenuate interfering signals. The triple conversion circuit structure allows highly flexible gain distribution at each stage. This proven receive design architecture enables elimination of unwanted signals through filters at each stage as well as optimized gain distribution.

A built-in 3.5-in TFT full color touch screen high resolution display with loads of information provides stress-free operability and visibility for the FT-991 user.

Advanced Spectrum Scope with ASC (Automatic Spectrum-Scope Control) located just below the LCD display gives the operator all the information for comfortable QSO on the DXing scene.

The new FT-991 also has Automatic Mode Select (AMS) function that instantly recognizes digital mode or FM analog mode and enables mutual communication.
