Faster DSP unit and in-house
DSP expertise
Icom brings out the best DSP performance combining
more than ten years of DSP technical know-how and much
faster DSP processors. Icom's in-house DSP experts have
developed a IC-7400 replacement that every operator will
be proud to own. In addition to the higher speed DSP,
the AD/DA converter, AK4620B, provides a higher dynamic
range and superior S/N ratio.
Double-conversion
superheterodyne
Introduced with the IC-7800, a double conversion
superheterodyne design, with an image rejection mixer
for the 2nd mixer stage is employed in the IC-7410. This
receiver design not only reduces the electronic
complexity, it greatly reduces the number of internal
distortion points from older triple and quadruple
conversion receivers.
+30dBm third-order intercept
point (IP3)
In Icom's continuing efforts
to create the best receiver, the design of the IC-7410
incorporates the latest in DSP software technology and
Icom's analog RF circuit experience for a +30dBm* IP3,
rivaling the IC-7600. The end result, clear reception of
weak signals surrounded by QRM from broadcast and
neighboring ham stations. * In 14MHz band.
Three first IF filters
(3/6/15kHz)
Optional 1st IF filters (6kHz,
3kHz) The IC-7410 accommodates three 1st IF filters with
the 15kHz, 1st IF filter supplied, while the 3kHz FL-431
and 6kHz FL-430 are optional for better
receiver performance by
protecting the desired signal from nearby strong
signals.
(Fixed for 15kHz in FM mode.)
Large, multi-function LCD
The display increases in width
from the IC-7400. The large multi-function LCD shows
frequency, 9-character channel name, channel number,
multi-functional meter (includes S-meter, RF output,
SWR, ALC and COMP level).
The dot-matrix portion of the
LCD shows the following items:
• Channel name
• Function key assignment
• Band scope
• RTTY decoder screen
• Memory keyer contents
• Graphical SWR scale
USB connector for PC control
The IC-7410 has a standard type B USB connector and
can be connected to a PC. Modulation input, audio
output, RTTY demodulator output and CI-V command can be
controlled via the USB cable. Also, the conventional
CI-V remote control jack is built in to the IC-7410.
RTTY demodulator and decoder
The built-in RTTY demodulator and decoder allow you
to instantly read an RTTY message on the display. No
external units or PC required. The built-in tuning
indicator visually helps in critical tuning.
Simple band scope
The built-in simple band scope shows the band
condition at a glance and is handy for searching for
active stations.
Wide range of DSP features
Using the latest algorithms, the digital features
give flexibility and speed needed for working in tough
RF conditions.
• Digital IF filter allows you to choose filter width
and shape factor
• Digital Twin PBT eliminates interference by changing
the IF bandwidth and/or shifting the IF frequency
• AGC loop management with programmable AGC time
constant
• Auto/manual Notch Filter provides more than 70dB
attenuation and eliminates unwanted beat tones
• Noise Reduction can enhance the receiver's
signal-to-noise ratio
• Noise Blanker reduces interference from pulse-type
noise
• RF Speech Compressor increases average talk power,
improving signal strength and readability
• User programmable tone control: microphone equalizer,
SSB transmit passband width, receive HPF/LPF and receive
audio equalizer
Ample CW functions
All of the following CW capabilities are included in
the IC-7410:
• Large CW pitch knob and independent BK-IN (break-in)
delay knob
• CW wave form controlled by the DSP
• 4 keyer channels with 70 characters of transmit memory
per channel
• Multi-function electronic keyer with adjustable keying
speed from 6–48 wpm, dot-dash ratio from 1:1:2.8 to
1:1:4.5 and paddle polarity
• Bug keyer and full break-in function
• Continuously adjustable CW pitch control from
300–900Hz
• Double key jacks (Front and rear panels)
• CW reverse
High frequency stability
A high stability TCXO crystal
oscillator provides ±0.5ppm of high frequency stability
over a wide temperature range (0°C to +50°C). This
allows for a long steady operating time in digital
modes.
Large heat sink
IC-7410 chassis When compared
to the IC-7400, the IC-7410's large heat sink improves
heat dissipation. Even during long hours of heavyduty
cycle operation, the IC-7410 provides stable output
power.
Other features
• Built-in voice synthesizer
• User programmable band edge beep
• VSC (Voice Squelch Control) function
• Two preamplifier types: Preamp 1: Improving IMD
characteristics, Preamp 2: High gain preamplifier
• 20dB built-in attenuator
• Built-in automatic antenna tuner
• CTCSS tone encoder and decoder
• Triple band stacking register
• Quick split and frequency lock functions
• RIT and ⊿Tx variable up to ±9.999kHz
• SSB/CW synchronous tuning
• 1Hz pitch tuning and display
• Program, memory, select memory, mode select and ⊿f
scans
• Automatic tuning steps
• AH-4 control circuit
• Large independent MIC/RF power and Notch knobs
Optional RS-BA1 IP remote
control software
The
optional RS-BA1 software allows you to use the
IC-7410 from another room using your home network or
even from a remote location over the Internet.
