Yaesu FT-991A
The New FT-991A – HF/50/144/430 MHz All-Mode “Field Gear” Transceiver
– Coming October 2016
The FT-991A is the next-generation of the widely popular FT-991. Like its predecessor, the FT-991A
is creatively designed to fit into a very compact (W9.0″ xH3.2″ x D9.3″) rugged case and will deliver up to 100 Watts solid output power (50 Watts on 144/430MHz) on SSB, CW, AM, FM, Packet and C4FM Digital on the popular HF/50/144/430MHzBands.
n keeping with the spirit of the rich performance of the FT-991, the new FT-991A provides two new stimulating and useful advanced features – a Real-time Spectrum Scopeand a Multi-Colour Waterfall Display.
The new dynamic real-time spectrum scope gives radio operators the ability to graphically view the location of signals on the band while they listen to the received audio allowing them to quickly move to the desired signal. The strength of signals on the band can readily be seen on the multi-colour waterfall display. Chronological order colour differentiation allows operators to easily recognise weak signals at a glance; signals that might otherwise be missed on the spectrum scope.
The new FT-991A naturally contains all the features packed into the original version of the FT-991 including a 3kHz Roofing Filter for the triple conversion receiver that effectively attenuates interfering signals and enables outstanding performance while still producing high quality audio. The 32bit high speed floating point DSP provides effective cancellation and reduction (DNR) of random noise, and the Auto Notch (DNF) automatically eliminates QRM
caused by dominant beat tones while the receiver’s Contour function and APF (Audio Peak Filter) can be used to further reduce undesired noise. A built-in 3.5inch full-colour touch screen high resolution display allows stress-free operability and visibility. for further detailed information, please refer to the attached specification sheet.
