Yaesu radio are among the best, and LDG makes a dedicated bolt-on tuner for the FT-897, but that leaves a big chunk of the Yaesu product line with no dedicated tuner. Of course, most LDG tuners will work just fine with Yaesu radios, but it sure would be nice to have it integrated to the radio.
LDG's new YT-100 is just that. An included CAT cable interfaces with your FT857, FT897 and FT-100 (including all D models). This makes it an integrated tuner powered by the interface. No extra power cables are needed. Just press the tune button on the tuner and everything else happens automatically! The mode is set to carrier and the RF power is reduced, a tune cycle runs and the radio is returned to the original settings.
The YT-100 does not work with FT-891, use Z-100 Plus, Z-11 Pro II, AT-100 PRO II, and AT-200 Pro II tuners and the LDG Y-ACC cable).
