Category: Radio, Communication
Group: Transceiver
Description: HF All Band Transceiver
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
