FT-991A All Band, All Mode (inc C4FM) Portable Transceiver
Yaesu FT-991A All Mode All Band Portable Transceiver
The FT-991Transceiver is the next generation in all mode, all band MF/HF/VHF/UHF transceiver with C4FM ( System Fusion) digital capabilities. The FT-991 includes multi-mode operation on CW,AM, FM, SSB and Digital Modes ( Packet Radio, PSK31, RTTY and C4FM) with 100W TX Output on HF and 6M ( 50W on VHF/UHF).
The NEW FT-991 incorporates as high resolution full colour 3.5" TFT touch panel for superior operator experience and visibilit, incorporating a high speed Spectrum Scope wiht ASC ( Automatic Spectrum-scope Control) built in.
The FT-991 is designed for the most competitive operating situations, with a suite of new features to enhance the experience of operating the FT-991 whether you are using it at home, mobile or in the field. The FT-991 will provide outstanding performance in providng access to the full range of exciting modes available on the ham bands today.
State of the Art Digital Signal Processing
Recognising the all important adage of ' You can't work them if you can't hear them' the FT-991A fetures a rugged state of the art highly balanced receiver circuit configuration. The high speed floating point DSP chip from Texas Instrument TMS320C6746 (3000MIPS /2250 MFLOPS) used in the Receiver design guarantees excellent intrerference rejection from real signals under real-world conditions, not only on the HF bands but also on VHF and UHF.
Selectable 3KHz and 15KHx Roofing Filters
The 1st IF incorporates selectable robust 3KHz and 15KHz roofing filters that very effectively attenuate interferring out of band signals. The triple conversion design allows a highly flexible gain distribution in each stage ensuring effective elimination of interfering signals through the use of filters and variable gain distribution.
Automatic Spectrum-Scope (ASC)
The Advanced Spectrum Scope located just below the LCD Frequency and Power Meter Display gives the operator all the information necessary for locating QSOs and now includes real time scope function wiith full screen display option
Large Colour TFT Touch Screen Display
The high-resolution (480 x 272 dots) 3.5-inch wide colour TFT touch screen displays the operating information and the status of the transceiver functions isplayed on this screen and provide the operator with easy to read operating information.
USB Serial Bus connection
The FT-991A can be connected to a computer using a standard USB cable for CAT control and firmware updates.
100 Watts of Solid Performance
The RF Power Ampifier in the FT-991A provides a clean and solid 100 Watts of Operating Power ( 50Watts on VHF/ UHF) and combined with a large heatsink and forced air automatic fan provides increased operating time and prevents overheating of the Amplifier.
Compact Lightweight and Portable
The FT-991A comes in a compact, lightweight package suitable for Portable, mobile and Fixed station installations. Measuring 229W x 80H x 253D mm (9" x 3.2" x 10"; 9.5lbs) and weighing only 4.3 kg, this robust full featured mobile/portable radio is ready to go when and where you are!
Internal Automatic Antenna Tuner
The Internal Automatic Antennae Tuner included in the package uses LC switching network with a large 100 channel memory. Tuning data is automatically stored and retreived to reduce tuning time when changing frequency.
