This Transceiver was purchased new, from MLS on 16 Nov 2015. It will be used as a back-up for the Kenwood TS-590, and for Digital Modes. It is unlikely that I will use the 2M or 70cms bands.
Sadly, in spite of returning it to the manufacturer twice, it was terribly 'deaf', which was checked by A to B switching between it and the Kenwood TS-590.... I kept it for 3 months, and sold it at quite a loss !!
Yaesu eventually realised that the transceiver was not as good as they thought, and after a year on sale, they upgraded to transceiver to an updated version - thje FT-991A. I have never tried this one, but you now (Feb 2017) can send the old 991 transceiver back to MLS to upgrade it to the 991A specification for £450 ... Making the original purchace price of the 991 at £995 almost £1500 when you add on the upgrade !!
The Manufacturers 'Blurb' The FT-991 is the next generation in all mode, all band MF/HF/VHF/UHF transceiver with C4FM (System Fusion) Digital capability. The FT-991 includes multi-mode operation on CW, AM, FM, SSB, and Digital Modes (Packet, PSK31, RTTY and C4FM), with 100 Watts of HF/50mhz Capability (50 Watts VHF/UHF).
The New FT-991 now includes a high-resolution full colour 3.5" TFT Touch panel for superior operability and visibility, incorporating a High Speed Spectrum scope with ASC (Automatic Spectrum-scope control) built right in.
State of the Art Digital Signal Processing Recognizing an all-important Golden Rule 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 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
Selectable 3 and 15khz roofing filters 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. This proven receiver design architecture enables elimination of unwanted signals through filters at each stage as well as optimized gain distribution.
Automatic Spectrum-Scope (ASC) 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.3.5The FT-991 could not provide functions easier than at your fingertips with a 3.5" Full Color TFT Display for Superior Operability and Visibility.
USB Capable 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).
100 Watts of Solid Performance The RF Amplifier in the FT-991 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.
Compact, Lightweight & Portable The FT-991 Comes in a compact, lightweight package suitable for portable, mobile and base installations. 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 Internal High Speed Automatic Antenna Tuner included in the package. The antenna tuner uses a LC switching network that has a large capacity 100 channel memory. The tuning data is automatically memorized to reduce tuning time when changing frequency.
High Accuracy TCXO +/-0.5PPM High Resolution DDS/PLL local Oscillator included as part of the standard package.
