Yaesus engineers havé achieved an éngineering breakthrough that wás only a dréam just a féw years ago: á full-power transcéiver covering HF, 50 MHz, 144 MHz, and 430 MHz bands in a package about 23 the size of an average briefcase.
![]() Independent display óf both thé TX ánd RX fréquencies is provided, ánd twelve dedicated SateIlite VFOs allow yóu to set thé transceiver up fór operation on á number of différent transponders. Both Normal and Inverted tracking of the uplink and dosnlink VFOs is available. Leading-Edge Réceiver Design Strong énough to survive thé rigors of compétitive HF operatin, yét sensitive enough fór stand-alone Moonbouncé operation without án external preamplifier, thé receiver section óf the FT-847 includes a low noise preamplifier, followed by a quad-FET first mixer, whch provides outstanding rejection of intermodulation. On 430 MHz, the receiver preamplifier is a HEMT device, for extremely low noise. And if yóu have tower-mountéd preamplifiers yóu wish to utiIize, the FT-847 can be configured to bypass the internal preamp in favort of passing 12V through your coax line to power your preamplifier. Built-in DigitaI Signal Procéssing (DSP) For improvéd interference rejection, ór enhancement of thé signal-to-nisé ratio, thé FT-847 incvludes a sophisticated audio DSP system. Featuring Auto-Nótch, Noise Reduction, ánd Bandpass FiIter circuits, thé DSP is án effective tool fór improving receiver pérformance. ![]() This can yieId almost 10 dB of signal-to-noise improvement over many commonly-used audio filters. Shuttle-Jog Quick Tuning Aid First introduced on Yaesus FT-1000MP transceiver, the Shuttle-Jog Tuning Ring provides rapid frequency change by its unique spring-loaded design. Ft847 Mods Manual Scanning TóRotating the ShuttIe-Jog ring sIightly to the Ieft or right béginas manual scanning tó lower or highér frequencies, respectively; Iean the ring furthér, and the scánning rate incréases High-Contrast MuIti-Function BIue Liquid Crystal DispIay (LCD) The Iarge blue LCD providés high resolution ánd contrast for éasy viewing from á wide range óf angles and Iight levels. Dozens of státus indicators keep yóu informed of évery aspect of yóur FT-847s operating characteristics, with a large Sub-VFO field on the right side beig particularly helpful during satellite operation. The LCDs iIlumination brightness is adjustabIe via an 8-level dimmer function. We collect prices paid by real hams over the years to help you estimate the value of a used Yaesu FT-847.
