CLOSEOUT -- ONE LEFT
IC-703 is Icom's product for the QRP enthusiasts. Focusing on QRP performance rather than an all-in-one solution, the IC-703 covers the Amateur Bands 160m to 6m*. Depending on the power supply the rig is capable of 5W @ 9.6VDC and 10W @ 13.8VDC, plus it has an internal antenna tuner. Icom engineers have addressed a lot of the concerns about current consumption and other comments gathered over the past two years regarding QRP performance. While it looks and feels like the IC-706MKIIG, this rig is a QRP version, not a replacement.
