Smoother FT8 Mode Operation with Constantly Evolving Firmware
The latest firmware offers smoother FT8 operation. One touch FT8 mode preset, Scroll mode, WLAN (Access Point) function and other updates are available.
HF/50/144/430 MHz Multimode
From HF to 50/144/430 MHz, you can enjoy a variety of bands in the D-STAR DV, SSB, CW, RTTY, AM and FM modes. The IC-705 receives continuously from 30 kHz through the 144 MHz band. You can also enjoy FM broadcast and air band reception.
RF Direct Sampling System
Configuration diagram of the RF direct sampling method
The IC-705 employs an RF direct sampling system, where RF signals are directly converted to digital data. Then processed in the FPGA (Field-Programmable Gate Array), making it possible to simplify the circuit construction as well as reducing internal noise that can mask weak signals.
* The down-conversion IF sampling method is used for 25 MHz and above.
Real-Time Spectrum Scope and Waterfall Display
Display example of real-time spectrum scope and waterfall
Performance seen with the IC-7300 and IC-9700 spectrum scope is at the tip of your fingers for field operation. You can quickly see band activity as well as finding a clear frequency, all in the compact radio and not as an expensive add-on. Scroll mode automatically keeps the operating signal within the scope range.
Large Touch Screen Colour Display
The large 4.3” colour TFT touch LCD, same size as the IC-7300 and IC-9700, offers intuitive operation of functions, settings, and various operational visual aids, such as the band scope, waterfall, and audio scope functions.

Introduction for Icom AH-705 Automatic Antenna Tuner
CloseCloseIngress Protection (IP) Code
Ingress Protection (IP) ratings define the level of protection provided by enclosures to prevent the ingress of foreign objects (dust) and liquid into the electrical equipment.
International Standard IEC 60529 outlines an international classification system that describes the sealing characteristics of electrical equipment.
The classification system uses the “IP” code, or “Ingress Protection” code, to define the level of seal.
An IP number contains two numbers (i.e. IP67) in most instances which relate to the level of protection provided by an enclosure or housing.
Either number may be shown as “X” (i.e. IPX6 / IP7X) to indicate the “X” part is not tested.
Degrees of Solid Particle Protection – 1st Digit
| IP6x | No ingress of dust; complete protection against contact. (Dust tight) |
|---|---|
| IP5x | Protected from the amount of dust that would interfere with normal operation. (Dust protected) |
Degrees of Liquid Ingress Protection – 2nd Digit
| IPx8 | Protected against continuous immersion in water. Depth and duration specified by model. |
|---|---|
| IPx7 | Protected against temporary immersion in water for 1 m (3.3 ft) for 30 minutes |
| IPx6 | Protected against water projected by powerful jets from any direction. 100 L per minute by a powerful jets (12.5 mm) for 3 minutes. |
| IPx5 | Protected against water projected by jets from any direction. 12.5 L per minute by a nozzle (6.3 mm) for 3 minutes. |
| IPx4 | Protected against water splashed against the equipment from any direction |
