Information

• COMPLETE HF Transceiver Icom's new IC-765 is an advanced HF all band Transceiver with a modern heavy-duty design for the serious HF enthusiast. The IC-765 features a 10 Hz digit in the display, a high speed PLL lock-up time including Icom's exclusive DDS circuit, a newly developed fully automatic Antenna Tuner, and many more advanced features. • FULLY AUTOMATIC HIGH SPEED Antenna Tuner The built-in CPU memorizes previously matched conditions on each band. Tuning speed is ultra fast since tuning starts from a previous position. If the Antenna Tuner cannot tune from a previously memorized preset position, the advanced re-try function automatically changes the preset position and memorizes the best preset position. • COMPLETE SYSTEM FOR CW OPERATORS The IC-765 has high-speed CW full break-in capability and many comfortable functions such as a electronic keyer, independent iambic key jack, keying speed control and CW pitch control. The IC-765 includes a 500 Hz CW narrow filter for effectively removing QRM on crowded bands. • 10 Hz DIGIT DISPLAY The large fluorescent display shows 7 digits for the operating frequency, meaning that the 10 Hz digit is also displayed. • BAND STACKING REGISTER Each band memorizes the last used frequency, mode, and IF filter condition (narrow or normal). The feature gives the IC-765 a simulation of 18 VFO capability (2 VFOsfor each band). • 105 dB DYNAMIC RANGE Receiver ability is fixed by the dynamic range. The Icom DFM (Direct Feed Mixer) system provides an excellent 105 dB dynamic range. • NEW PLL CIRCUIT-ADOPTED DDS The advanced Icom DDS (Direct Digital Synthesizer) System ensures high speed PLL lock-up times, clear signal emissions, and high C/N characteristics. A high-speed PLL provides very fast CW full break-in performances. • OTHER CONVENIENT FEATURES - 10 dB preamp - Selectable attenuator, 10, 20, 30 dB - 99-channel memory - Split memory on channels 90 ~ 99 - Built-in 500 Hz CW narrow filter - Programmed scan, memory scan and selected memory scan - Separate LED lights on a selected memory channel - IF shift - Notch filter - Low distortion 100 W power Amplifier - Large heatsink and cooling fan - Fast/Slow/OFF selectable AGC - RF-type speech compressor - New-type noise blanker - DATA switch for advanced data communications - Cl-V bus line
