Icom IC-7410 transceiver, HF+50Mhz ,100 W

The Icom IC-7410 provides professional performance in the 160 to 6 meter amateur bands.

This specialized HF rig employs the same high grade DSP unit and double conversion super-heterodyne system developed from the latest technology used in the IC-7600, IC-7700 and IC-7800 series.

It features a 15kHz roofing filter. In addition, when used with the optional FL-430 and FL-431 filters, narrow mode signals are protected from adjacent inband signals.

The 3kHz first IF filter is especially effective in the CW and SSB modes. It utilizes Icom's proven IF-DSP technology.

Like the IC-7400, it features a sharp black and white LCD. In fact, the IC-7410 liquid crystal display is actually 10mm wider than the IC-7400 display.

It features a superior general coverage receiver covering 30 kHz to 60 MHz with +30dbm 3rd order intercept point receive performance and ±0.5 p.p.m. stability. There is a built-in bandscope function, and Baudot RTTY capability. Other refinements include: ±9.999 kHz RIT, BPF, quick split function, band edge beep and CW keyer (6-48 WPM). A large chassis heatsink is employed. There is a built-in tuner. Power is 100 watts. There are both CI-V and USB ports on the rear panel. This radio requires 13.8 VDC at 23 amps

Faster DSP unit and in-house DSP expertise

The IC-7410 employs a much higher speed DSP unit compared to the IC-746PRO/7400's DSP unit. The AD/DA converter AK4620B allows for a high dynamic range and superior S/N ratio.

Icom has many years of DSP expertise, and has been key in development of the technology. The IC-7410 represents the latest in digital achievement and performance.

Double-conversion superheterodyne

The IC-7410 employs a double conversion superheterodyne system which has an image rejection mixer for the 2nd mixer stage. When compared to a typical triple-conversion system, signal distortion is dramactically reduced.

+30dBm third-order intercept point (IP3)

Icom's analog RF circuit experience  combined with the latest DSP software technology results in +30dBm IP3 equivalent to the IC-7600. Even in tough RF conditions, such as interference by broadcast stations or strong neighboring ham stations, a weak signal can be clearly received by the IC-7410.

Three first IF filters (3/6/15kHz)*

The IC-7410 comes with a built-in 15kHz 1st IF filter and can accept up to two optional filters (3kHz FL-431 and 6kHz FL-430). By changing the first IF filter width according to the operating mode, the desired signal is protected from the influence of nearby strong stations. The 3kHz first IF filter is especially effective in the CW and SSB modes. (Fixed for 15kHz in FM mode.)

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 stable operating time in modes such as RTTY.

Large, multi-function LCD

The display increases in width from the IC-746PRO/7400. The large multi-function LCD shows frequency, 9-character channel name, channel number, multi functional meter (includes S-meter, RF output, SWR and ALC level). The dot-matrix portion of the LCD shows the following items:

• Channel name
• Band scope
• Memory keyer contents
• Function key assignment
• RTTY decoder screen
• Graphical SWR scale

Simple band scope

The built-in simple band scope shows the band condition at a glance and is handy for searching for active stations.

RTTY demodulator and decoder

The built-in RTTY demodulator and decoder allows 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.

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 improve operating efficiency
• 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

Built-in antenna tuner

The internal antenna tuner covers from 1.8MHz to 50MHz and automatically tunes for low SWR. Variable capacitors provide higher accuracy than a typical mechanical relay tuner. Once you transmit on a frequency, the tuner can instantly retune the frequency using its built-in memory.

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.

Large heat sink

When compared to the IC-746PRO/7400, the IC-7410's large heat sink improves heat dissipation. Even during long hours of heavy-duty cycle operation, the IC-7410 provides stable output power.

Optional RS-BA1 IP remote control software

The optional RS-BA1 allows you to use the IC-7410 from another room using your home network or even from a remote location over the Internet. Most settings such as filter width, AGC constant, etc., can be controlled from your PC.
