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!


160-6m full coverage internal automatic antenna tuner, and low current PA


Auto power scale meter


Low current mode


Stay on frequency, indoors or out


High sensitivity


Remote control head allows for easy operation while outdoors


Built-in memory CW keyer


Clean FSK, RTTY


455kHz IF filter selections


Built-in SWR analyzer


Spectrum scope


Other outstanding features
