The IC-7410 by icom has been designed as an HF/50MHz specialized rig with excellent performance and features in this category. The IC-7410 employs high grade DSP unit and double conversion super-heterodyne system developed from the latest technology used in our higher grade rigs such as the IC-7800/7700/7600 series. In addition, the IC-7410 comes with a built-in 15kHz 1st IF filter and can accept up to two optional filters (3kHz/6kHz). When used with these 1st IF filters, narrow mode signals such as the CW and SSB modes are protected from adjacent strong signals.
+30dBm 3rd order intercept point (in 14MHz band)
Double conversion superheterodyne system improves inband IMD characteristics
32-bit floating point DSP unit
Built-in 15kHz first IF filter and optional 3kHz and 6kHz first IF filters
Large monochrome LCD display
±0.5ppm frequency stability
Built-in simple band scope
Built-in automatic antenna tuner
All mode (SSB/CW/RTTY/AM/FM)
Optional RS-BA1 for IP remote control
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.
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 dramatically 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:
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)
Built-in antenna tuner
The internal antenna tuner covers from 1.8MHz to 54MHz 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.
