** Free Shipping **

The LDG IT-100 is an automatic tuner intended for use with modern Icom transceivers. It works with any Icom transceiver that supports an AH-3 or AH-4 Icom tuner; a partial list of compatible units includes: IC-706, 703, 718, 7000, 7100, 7200, 7300, 7410, 746, 756, 7600, 7610. The interface cable is included. The IT-100 connects to the radio via its Tuner jack to control the tuning cycle; the transceiver’s Tune button controls the tuner. The Tuner jack also powers the tuner, so it requires no external power supply. Since the IT-100 is matched to your specific rig, you just press the Tune button on the radio, and the rig and tuner do the rest: reduces power, transmits a carrier, automatically matches the antenna to the rig, then restores the original power and mode.

Like most LDG tuners the IT-100 operates automatically, beginning a tuning cycle when the user presses the tune Button the radio or tuner. It also features LDG’s advanced memory tuning, providing 2,000 memory locations; when tuning near a previously used frequency it will recall the settings for nearly instant tuning. It learns your favorite frequencies and bands as you use it. You can also start a tuning cycle manually whenever necessary.
