                                    430MHz ALL-MODE TRANSCEIVER INCORPORATING A MICROCOMPUTER
CPU control with ICOM's original programs provides various
operating capabilities. A no-backlash dial controls by
ICOM's unique rotary encoder circuit. The Band-edge detector
and the Endless System provides out-of-band protection.
Variable capacitors and dial gear are not utilized and
therefore provide problem-free use. The IC-471 A/E provides
FM, USB, LSB, CW coverage in the 430 ~ 440MHz (IC-471 A: 430
~ 450MHz) frequency range. Thus the IC-471A/E can be used
for mobile, DX, local calls, satellite work, and moonbounce.
MULTI-PURPOSE SCANNING
Memory Scan allows you to monitor all different memory
channels or only those stored with a particular mode.
Program Scan provides scanning between two programmed
frequencies. Auto-stop scanning when a signal is received,
in any mode.
DUAL VFO'S AND 32 MEMORY CHANNELS
Two separate VFO's can be used either independently or
together for simplex operation, and any desired frequency
split in duplex operation.
The IC-471A/E has 32 memory channels and each channel stores
the operating frequency as well as the mode, duplex/ simplex
and subaudible tone frequency (IC-471 E provides provides
tones only when an optional unit is installed).
CONTINUOUS TUNING SYSTEM
ICOM's new continuous tuning system features a luminescent
display that follows the tuning knob movement and provides
an extremely accurate readout. Frequencies are displayed in
7 digits representing 100MHz to 100Hz digits.
Automatic recycling restarts tuning at the top of the band,
i.e., the high edge when the dial goes below the low edge.
Recycling changes the high edge to the low edge as well.
Quick tuning in 1KHz steps is available, and fine tuning in
10Hz steps in the SSB and CW modes, and 5KHz steps and 1 KHz
steps in the FM mode, is provided for trouble-free QSO.
EASY-TO-READ DISOLAY
The IC-471 A/E employs an easy-to-read large luminescent
display. This displays the operating frequency as well as
the VFO in use, operating mode, RIT snift frequency, duplex
mode, scan mode, etc.
EASIER OPERATION AND LIGHTER WEIGHT
The IC-471 A/E is the most compact, lightest weight all-mode
430MHz transceiver. It is the first to use a pulse power
supply (option) in communication equipment, for lightweight.
A 50mm-diameter large tuning control knob is provided for
smooth and easy tuning. Easy to use control knobs are
provided for both receiving and transmitting. An LED
indicates the transmit or receive mode.
SUITABLE FOR BOTH FIXED AND PORTABLE STATIONS
The transceiver can be operated with a self-contained
117/240V AC (option) or 12V DC power supplies. A convenient
Dial Lock switch is included for mobile operation as well as
an easy-carry handle. An effective Noise Blanker reduces
pulse noise. The IC-SM6, high quality stand microphone
(option), is suitable for fixed station operation. A
powerful audio output, 2.0 watts at 8 ohm, provides easy
listening even in noisy surroundings.
OUTSTANDING PERFORMANCE
The RF amplifier and the first mixer circuit incorporate
FET's, and other circuits provide excellent Cross Modulation
and Two-Signal Selectivity characteristics. The IC-471 A/E
has excellent sensitivity demanded especially for mobile
operation, high stability, and utilizes Crystal Filters
having high shape factors and exceptional selectivity.
The transmitter uses a balanced mixer in a double conversion
system, a band-pass filter and a high-performance low-pass
filter. This system provides distortion-free signals with a
minimum spurious radiation level.
