[. . . ] What's more, the SELECT knob allows "channelized" tuning in minimum steps of 1 kHz on SSB/CW, or 5 kHz on FM, for quick and easy tuning around the band. All important keys are strategically placed around the front panel, for quick access. ·EASY-TO-USE "SCROLLING FRONT PANEL" KEYS : The compactness of the FT-80C is made possible by the easy-to-use "multi-function" keys, which allow adjustment of a number of transceiver operating functions during operation. Pressing the [FUNC] key allows selection of the operating function row, using the Selector knob, and you may then press the [A], [B], or [C] key, as needed, to change the Multi Function Keys A key B key AB A=B MFa (VFO A/B /Selection) (Equalize VFOs A/B) MFb MFc MFd MFe* MFe MFf MFg MFh MFi MFj MFk MFl MFm MFn MFo MFp MFq (Write to Memory) (Quick Memory Store) (Repeater On/Off) (CTCSS/DCS On/Off) (Split Tone Encode) (ARTSTM On/Off) (Scan Start) (Spectrum Scope) (Meter Mode) (CW Spot) (ATU/ATAS On/Off) (Noise Blanker On/Off) (RX Preamp On/Off) (RX Normal Fltr. ) (Keyer Mem. [. . . ] The FT-80C's DSP Unit features a 24-bit high-tech D/A chip for signal processing. BANDPASS FILTER : Separate DSP Bandpass Filters for Voice and CW augment the analog filters for enhanced interference rejection. For Voice modes, you get 16 High-Pass Filter cutoff frequency selections, and 32 Low-Pass Filter selections, for a total of 512 combinations. And for CW, you may choose bandwidths of 240 Hz, 120 Hz, or a razor-sharp 60 Hz. · DSP AUTO-NOTCH FILTER : To reduce interference caused by annoying carriers within the audio passband, the DSP Auto-Notch provides a significant reduction in the interference level. If multiple carriers are present, the DSP will detect and notch all the carriers present. ·DSP NOISE REDUCTION : The very effective Noise Reduction filter of the FT-80C utilizes as many as 16 noise-reduction algorithms, for use in a wide variety of noise environments, without introducing appreciable distortion on the desired signal. Operator fatigue is reduced, and signal-to-noise ratio is significantly enhanced. ·DSP MICROPHONE EQUALIZER : To match the FT857's TX audio response to the waveform produced by your voice and the microphone in General use, the DSP system includes a four-position Mic Frequency Range: Equalizer circuit. The resultMHz, increased 420-470 MHz Receive: 0. 1-56 MHz, 76-108 is 118-164 MHz, "talk power" as : extraneous 2 Meters, Transmit 160 - 6 Meters, frequencies are suppressed, allowing all available bands only) be 70 Centimeters (Amateur power to concentrated into your(Alaska Emergency Frequency/USA Version) 5167. 5 kHz voice's pattern. ADVANCED FEATURES FOR ACTIVE DXers ·IF Shift : Use the IF SHIFT feature to vary the center frequency of the IF passband, so as to eliminate interference above or below the current operating frequency. ·IF Noise Blanker : Optimized for use in the mobile environment, the FT-80C includes a highlyeffective IF Noise Blanker specifically designed for suppression of ignition and other pulse-type noises. ·Smart SearchTM : When visiting a new city, use the Smart Search system to scan the FM/AM Mode for activity. When busy channels are found, they will be automatically loaded into a special Smart SearchTM memory bank, for easy recall. ·Spectrum Scope : If you have to be away from your radio for a few minutes, turn on the Spectrum Scope to keep watch on band activity. The Spectrum Scope will create a bar-graph display of activity on channels above and below your current operating frequency. ·ARTSTM(Auto-Range Transponder System) : During Search-and-Rescue operations, the ARTSTM ACTIVE-TUNING ANTENNA SYSTEM (ATAS-120 Option) Yaesu's patented ATAS-120 Active-Tuning Antenna System provides a compact, yet efficient, automaticallyadjusting antenna for mobile, portable, or apartment-balcony use!Utilizing DC voltages fed from the FT-80C, the ATAS-120 automatically adjusts its length longer or shorter, with the FT-80C feeding a tiny amount of power for SWR detection by its internal directional coupler. When the best impedance match is found, tuning automatically stops, and operation can begin. Specified for operation on the 7/14/21/28 MHz Amateur bands, the ATAS120 contracts fully for use on the 50/144/430 MHz bands, providing a low SWR for local FM work (where vertical polarization is predominant). And if you're an apartment dweller, use the optional ATBK-100 Antenna Base Kit, which provides an outstanding counterpoise to ensure low-angle radiation on the VHF/UHF bands. The FT-80C provides up to 200 "Main" memory channels, each of which may be named with an Alpha-Numeric label of up to eight characters. These 200 Memories may be separated into as many as 10 Memory Groups of 20 Memories each. [. . . ] For added convenience, you also get a "Quick Memory" and a "Home Channel" on each band, plus Five pairs of band-limit memories, to let you restrict operation to a sub-band, if you UPGRADE WITH COLLINS® MECHANICAL FILTERS FOR SSB AND CW (0ption) To enhance performance on both receive and transmit, high-performance Collins® Mechanical Filter options are available for both SSB and CW. For SSB, the 2. 3 kHz, 10-pole YF-122S option provides a very flat passband response, for natural-sounding transmit audio, along with excellent skirt selectivity. And for CW, the 500 Hz, 7-pole YF-122C and 300 Hz, 7-pole YF-122CN options help separate signals on a crowded band in a contest. HIGH-RESOLUTION DOT-MATRIX DISPLAY The large 2. 1"x0. 69"(53. 4x17. 2 mm) multi-color display provides easy-to-read indication of many operating functions. The color may be chosen from among 32 different color selections, and may be programmed to show different colors on each band, mode, Memory Group, or even to track signal strength and power output by Large Character mode AND MUCH, MUCH MORE.
