It is a SUPERB rig for the QRP enthusiast and does just about everything that one could want.
The IC703 features a built-in DSP filter and auto ATU as well as speech processing an a CW keyer with 3 message memories.
It is an ideal compact and portable "all-in-one" ham station for QRPers.
Icom's DSP technology allows you to pick-out the weak signals!
DSP capabilities give you tools to reduce interfering signals, or just to dig weak signals out of the dirt. The noise reduction separates desired signals from noise and reduces the noise components for a clearer received signal, while the auto notch tracks and eliminates interference from a solid tone signal.
160-6m full coverage internal automatic antenna tuner, and low current PA
The newly designed PA unit and antenna tuner, specifically designed for the IC-703, extends operating time by reducing the voltage and current consumption. The antenna tuner utilizes low current latching relays to cover 160ľ6m. While on a 9.6V DC source or less than 11V DC, many functions of the IC-703 are controlled by the microprocessor to extend the battery life.
While in low current mode, the IC-703 automatically switches to 5W output power (2W AM). While on 13.8V DC, the output switches to 10W (4W AM). Antenna tuner PA unit
Auto power scale meter
There's no need to calculate the output power, as the IC-703 automatically scales the power meter according to the output power of the rig. The full scale reading of the meter will indicate the power output setting of the rig. For example, if you are running at 5W mode, the full scale reading will be 5W. (Available power settings are 10/5/2.5/1/0.5W)
Low current mode
By using power efficient components for the PA, antenna tuner and the PLL circuits, the IC-703 is designed for maximum efficiency at 9.6V DC. When using the optional BP-228 battery pack, the IC-703 automatically switches into low current mode, thus allowing operation time of up to 7 hours (Tx:Rx:Stand-by =0.5:0.5:9 in SSB mode).
While operating on high power, or 13.8V DC, the IC-703 can safely operate at a full 10W even if the power source drops to 11V DC.
Stay on frequency, indoors or out
Whether safe indoors or exposed to the cold temperatures outdoors, the IC-703 will be right on frequency with the standard ▒0.5ppm TCXO.
The IC-703's receiver performance is in the same class as that of high end base stations: 0.16ÁV at 10dB S/N for 1.8 to 30MHz bands and 0.13ÁV for 50MHz at 10dB S/N (in SSB and CW modes).
Remote control head allows for easy operation while outdoors
Operate while hiking without fumbling for the controls. Use with the optional OPC-581 (3.5m; 11ft) or OPC-587 (5m; 16ft) separation cables to remote the control head where its easy to see and use, allowing the compact body, measuring only 167(W) Î 58(H) Î 200(D) mm and weighing 2.0kg, to be carried out of the way.
Built-in memory CW keyer
The IC-703 has a built-in CW Memory Keyer with three memory locations and up to 50 characters per memory location.
Other keyer features include a variable CW pitch control (300.900Hz); operation with a bug; iambic paddles; or straight key. All these functions are available even when in low current mode.
Clean FSK, RTTY
Utilizing the TRUE RTTY mode, FSK, the IC-703 generates the tones internally for the cleanest possible signal on the band.
Also, whether operating FSK or AFSK data, you can tweak the IC-703 to be the perfect portable RTTY machine by adding the optional FL-52A filter.
455kHz IF filter selections
The 455kHz IF allows you to upgrade the standard 455kHz filter, FL-65, to improve your selectivity by installing an optional filter into the filter slot.
Built-in SWR analyzer
Check out your antenna's SWR with the internal SWR analyzer. The resolution of the IC-703's SWR graph bandwidth is adjustable from 10/50/100/500kHz.
Catch band activity at a glance with the spectrum scope. With the operating frequency in the center of the display, each step either to the left or right of center is selectable from 0.5/1/2/5/10/20/100 kHz steps.
