Icom IC-7410 HF + 50MHz radioamaterska radijska postaja bazna

 

Designed as an HF/50MHz specialized rig with excellent performanceand features in this category.


The appearance and operability of the IC-746PRO/7400 has been mostly been retained to maintain the familiarity in usability from old to new.
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 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
Major selling points:

  • +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. The Icom in-house DSP expertise is the result of more than ten years accumulated technical know-hows.
We know how to bring out the best performance of the DSP and various digital functions.

Double-conversion superheterodyne dramatically improves inband IMD

   
  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, the double-conversion system dramatically reduces signal distortion and provides a high-fidelity RF signal to the DSP processor


+30dBm third-order intercept point (IP3) in 14MHz
Icom’s analog RF circuit experience over a number of years 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 neighbouring 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 multifunction
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
  • Function key assignment
  • Band scope
  • RTTY decoder screen
  • Memory keyer contents
  • 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 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.

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 1.9MHz 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.
