The MFJ-706 is an Emergency Communications (EmComm) box that turns your ICOM IC-706 into an instant and foolproof emergency communications center. It covers all HF, VHF and UHF amaterur radio frequencies available on the IC-706.
It is literally a complete grab-and-go communications center that can provide a full 100 Watts SSB/CW signal simply by plugging into any available vehicle cigarette lighter socket or light-duty 10 to 15 Amp 12 VDC power supply.
An MFJ exclusive PeakPowerBoostTM circuit delivers instantaneous SSB/CW power peaks using several Farads of super capacitance.
A built-in, full range automatic antenna tuner turns any random wire or other antenna into a highly effective HF antenna. Simple foolproof automatic tuning is done with a single push of a button.
