The new “A” version of the FT-991, which will be offered from the end of 2016 on, brings two new features:
- Realtime spectrum display. The transceiver displays the received spectrum while listening, i.e. the receiver is not muted.
- The waterfall diagram is now in colour. The greatly facilitates the identification display of signal strength of all signals.
The Yaesu FT-991 is the result of a continous development of one of the most successful transceivers by Yaesu – the FT-897D. This up-to-date radio offers all features a passionate radio amateur is looking for: full 100 W transmit power on shortwave from 160 to 10m, 100 W on 6m, 50 W on VHF and UHF. Plus operation in all modes (SSB, CW, AM, FM, data modes) and including the latest digital ‘System Fusion’ C4FM technology.
Despite the compact size the FT-991 is easy to operate due to the easy to read 3.5″ colour touch LC display. Most often needed controls are accessible through the touch panel or on the front of the transceiver, the necessity to access the menu is reduced to a minimum. And the relatively small case of the FT-991 can even accomodate an automatic antenna tuner, which tunes antennas from 16.5 to 150 Ω, sufficient for most not perfectly matched antennas.
Like all recent transceivers the FT-991 uses up-to-date DSP technology. This ensures a perfect receiver with freely adjustable filter widths, selectable notch filters and adjustable noise reduction. On the transmit side a parametric microphone equaliser can be used for outstanding modulation. A voice memory keyer is provided as well. The well known Yaesu features for comfortable telegraphy operation like zero beat tuning or a contest keyer are of course included as well.
Fans of digital modes will find an USB interface integrated into the FT-991. This interfaces provides an external sound card and a serial CAT interface to your computer. Just install the drivers and a software for digital modes and you are on the air with modes like PSK31, RTTY, Whisper, SSTV and much more.
Be prepared for the digital future! Yaesu includes the latest ‘System Fusion’ technology in the FT-991 transceiver (VHF/UHF only). This enables you to use the System Fusion DR-1XE repeaters with the digital C4FM modulation. This ‘C4FM’ modulation offers benefits like a good legibility, high compression rates and variable bandwith usage. This enables you to transmit serial data in parallel to the digital voice data (the full rate data mode is not suported by this radio).
