Yaesu FT-991 HF/VHF/UHF Multi-Mode Transceivers
Yaesu FT-991 HF/VHF/UHF Multi-Mode Transceivers are the next generation in all mode, all band MF/HF/VHF/UHF transceiver with C4FM (System Fusion) Digital capability. FT-991 transceivers include multi-mode operation on CW, AM, FM, SSB, and Digital Modes (Packet, PSK31, RTTY and C4FM), with 100 Watts of HF/50 MHz capability (50 Watts VHF/UHF).
FT-991 transceivers include a high-resolution full-color 3.5 in. TFT touch panel for superior operability and visibility, incorporating a high-speed Spectrum Scope with ASC (Automatic Spectrum-scope Control) built right in.
Recognizing an all-important Golden Rule of Amateur Radio - "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 high-speed floating point DSP 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 incorporates 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.
Their advanced Spectrum Scope with ASC (Automatic Spectrum-Scope Control) located just below the LCD display gives the operator a great view of the band activity to make easy DX contacts.
These FT-991 transceivers could not provide functions easier than at your fingertips with a 3.5 in. full color TFT display for superior operability and visibility.
These rigs 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, and Shift).
The RF amplifier in FT-991 transceivers provides a clean and solid 100 Watts of 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.
These radios are a compact, lightweight chassis suitable for portable, mobile and base installations. Measuring 8.8 W x 3 H x 9.9 in. deep at just 9.7 pounds, this robust full-featured mobile/portable radio is ready to go when and where you are!
The integral internal high-speed Automatic Antenna Tuner included in the transceiver uses an LC switching network that has a large-capacity 100 channel memory. The tuning data is automatically memorized to reduce tuning time when changing frequency.
A plus/minus 0.5ppm High Resolution DDS/PLL Local Oscillator included as part of the standard radio package.
