Frequency Ranges: RX 30 kHz – 56 MHz, 118 MHz – 164 MHz, 420 MHz – 470 MHz (specified performance, amateur bands only).+/-0.5PPM High Resolution DDS/PLL local Oscillator included as part of the standard package. The tuning data is automatically memorized to reduce tuning time when changing frequency. The antenna tuner uses a LC switching network that has a large capacity 100 channel memory. Internal High Speed Automatic Antenna Tuner included in the package. Measuring 8.8″(W) x 3″ (H) x 9.9″ (L) at just 9.7 pounds this robust full featured mobile/portable radio is ready to go when and where you are! Internal Automatic Antenna Tuner The FT-991 Comes in a compact, lightweight package suitable for portable, mobile and base installations. The RF Amplifier in the FT-991A provides a clean and solid 100 Watts of Operating Power (50 Watts VHF/UHF) and is combined with a large heat-sink and forced air automatic cooling fan to increase operating time and prevent overheating. The FT-991 can be connected to a computer using a USB cable for CAT control and firmware updates, or the use of an optional SCU-17 Interface Unit to support USB Audio In/Out, TX Control (PTT, Key, Shift). The FT-991 could not provide functions easier than at your fingertips with a 3.5″ Full Color TFT Display for Superior Operability and Visibility. Automatic Spectrum-Scope (ASC)Īdvanced 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. This proven receiver design architecture enables elimination of unwanted signals through filters at each stage as well as optimized gain distribution. The triple conversion circuit structure allows highly flexible gain distribution at each stage. The 1st IF frequency incorporates selectable robust 3 kHz and 15 kHz roofing filters that effectively attenuate interfering signals. The high-speed floating point TMS320C6746 DSP chip (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. Recognizing an all-important Golden Rule Amateur Radio – “You cannot work them if you cannot hear them”– the FT 991A features a rugged state-of-the-art highly balanced receiver circuit configuration.
