Description :

Compact and lightweight design

Real "base station radio" performance and functions packaged in a compact size of approximately 7.9 x 3.3 x 3.1 inch (20 × 8.3 × 8.2 cm). The weight is approximately 1 kg (including BP-272 battery pack). Its compact and lightweight design enables you to hold it with one hand.

Multi-band

From HF to 50/70/144/430 MHz (70 MHz band will be featured for the European version) in D-STAR DV, SSB, CW, AM and FM modes. The IC-705 receives continuously from the medium wave broadcast band to 144 MHz band. You can also enjoy FM broadcast and air band reception.

RF direct sampling system

The IC-705 uses the RF direct sampling method (down-conversion IF sampling method for 25 MHz and above) which greatly reduces distortion. The high speed & high resolution real-time spectrum scope and waterfall display are incorporated in a compact design for the first time in this class.

Large touch-screen color display

The large 4.3-inch (11cm) touch screen color display dramatically improves visibility and operability in the field.

Bluetooth and wireless LAN

Bluetooth and wireless LAN are built-in. They can be used for smartphone linking and remote control, and also for Bluetooth headsets.


Backpack and Side / Rear Panel View

Backpack

The IC-705 fits perfectly in the optional dedicated LC-192 multi-function backpack. The backpack includes holes for the antenna and for passing through coaxial cable and microphone cable. You can easily operate the IC-705 with it in the backpack.

QRP / QRPp operations

Despite being a portable radio, it achieves the maximum output power of 10W with a 13.8 VDC external power supply. When the standard BP-272 Li-ion battery pack is used, operation at the maximum output power of 5W is possible. True 5 watt QRP as well as 0.5 watt QRPp are supported.

D-STAR functions

The IC-705 is fully equipped with functions to enjoy D-STAR comfortably, such as the DR function and Terminal Mode & Access Point Mode. In addition, you can send / receive and view saved photos using only the IC-705 without any application software.

Antenna and SP-Mic come standard

A whip antenna for VHF/UHF and speaker-microphone come standard. The speaker-microphone is equipped with programmable buttons assignable to various functions, such as frequency adjustment and volume control.

GPS and logger

A high-performance GPS antenna is incorporated. In the D-STAR DV mode, you can send and receive location information while communicating. This high-performance GPS enables various functions such as GPS log function and repeater search function.

MicroSD card slot

The IC-705 is equipped with a microSD card slot that can be used for firmware upgrades, programming and so on, as well as voice recordings and saving GPS log data.
