Yaesu FT-991A

YAESU FT-991A KW / 6m / 2m / 70cm Multimode Transceiver

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.  

Support for Advanced C4FM Digital Functions 

 

• V/D Mode for Simultaneous transmission of Voice and Data with powerful error correctio optimised for mobile operation & Voice FR mode for high quality audio transmission. #
• AMS (Automatic Mode Selection) function instantly recognises digital mode or FM and enables mutual communictions
• GM (Group Monitor) function allows on screen checking of group members with in range
• 126 different DSQ (Digital Squelch) enables unique selection of stations.
  # Sending and Receiving of image data using C4FM is not supported in the FT-991
