Group: Transceiver
Description: HF All Band Transceiver General Coverage Receive
Information:
                                    ■ COMPLETE HF RADIO
► COMPACT SIZE
•ALL BAND, ALL MODE, ALL SOLID-STATE
The small size of the IC-735, only 94mm(3.7")(H) x
241mm(9.5") (W) x 239mm(9.4")(D), simplifies installation in
most mobile and portable situations such as automobiles,
airplanes, boats or suitcases.
The IC-735 covers all Amateur HF frequencies from 1.8MHz to
30MHz, including the three new bands of 10MHz, 18MHz and
24MHz. It offers not only SSB, but also CW, AM and FM
operating modes. All circuits in the IC-735, including the
driver and final power stages, are completely solid-state,
and the transceiver provides about 100 watts output.
•GENERAL COVERAGE RECEIVER
»RTTY OPERATION POSSIBLE
The IC-735 features general coverage receive capability with
a tuning range from 100kHz to 30MHz continuous, made
possible by an up-conversion system which uses a high side
IF and a CPU control system.
The rear panel of the IC-735 has easy-to-access terminals
for AFSK (audio frequency shift keying) RTTY operation.
OUTSTANDING RECEIVER PERFORMANCE
• 105dB DYNAMIC RANGE
»I COM'S DFM SYSTEM INSTALLED
The IC-735 has a 105dB dynamic range with a 70.4515MHz first
IF circuit which uses two quality crystal filters that
virtually eliminate spurious responses.
The ICOM DFM (Direct Feed Mixer) feeds the incoming signals
directly into a high level first mixer developed by ICOM.
This advanced system produces a higher spurious response
rejection ratio, a higher receiver sensitivity and a wider
dynamic range.
>PBT AND NOTCH CONTROL
• PREAMP AND ATTENUATOR INCLUDED
The IC-735 has a built-in Passband Tuning system that allows
continuous center frequency adjustment of the IF passband.
Additionally, a sharp IF notch filter provides clear
reception even in the presence of strong interference.
Both a 10dB preamplifier plus a 20dB attenuator are
installed as standard equipment. The preamplifier increases
receiver sensitivity while the attenuator provides added
protection from intermodulation problems.
■ SIMPLE PANEL DESIGN
► ROTARY DIAL DIGITAL TUNING SYSTEM
• EASY-TO-OPERATE, MULTIPURPOSE TUNING CONTROL
ICOM'S new continuous tuning system features a backlit LCD
(liquid-crystal display) that closely follows the TUNING
CONTROL, and provides an extremely accurate readout. The
VFO, with 10Hz digital tuning steps, gives the feel of an
analog tuning system.
The MAIN TUNING CONTROL plus adjacent switches select either
the 10Hz, 1kHz or 1MHz tuning speed and, also, control band
changes.
• CONVENIENT, FRONT SWITCH PANEL
The front-mounted SWITCH PANEL is a new idea from ICOM which
groups lesser used controls in one compact area behind a
protective cover.
