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


455kHz IF filter selections

Built-in SWR analyzer

Spectrum scope
