From the outside, it's quite a simple looking device. The front has a tune button and red status indicator light. The back is a little more complex with 6 connections for antenna, ground, transmitter, connection to radio, port for remote trigger, and pass through for CAT function.
The LDG YT-100 auto tuner fills a need for Yaesu transceiver owners who own the FT-100, FT-100D, FT-857, FT-857D, FT-897 and FT-897D. 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. It operates from 160 to 6 meters with from 1 to 100 watts.
Specifications:
Continuous coverage 1.8 to 54 MHz
RF Power: 1 to 100 watts SSB, CW and digital modes.
Tunes 4 to 800 ohms. (16 to 150 on 6 meters)
2000 memories sorted by frequency.
Dimensions: 7.0”L, 7.0”W, 1.5”H. Weight: 20 ounces

One of the great features of the YT-100 is that it tunes a wide range and has 2000 memories. I use mine portable on several different antennas. I've had it just under 2 years and it works like a champ. I love how simple it is to tune with the Yaesu FT-897D.
While over building the 6m yagi with the guys a few weeks ago, I triggered a tune cycle. When I thought it was done, I began spinning the VFO knob to a different frequency, but did it too soon, as the tuner hadn't found a good match yet. After that, it went haywire and didn't seem to want to work properly. We were done testing antennas anyway, so I packed it up for the night.
When I got home, I thought that I'd open it up and see if there was a reset function. I hoped this would maybe help if I had done any damage and also reset the 2000 memories. Since I use it on several different antennas, I thought that might be beneficial to start over.
When I opened it up, I didn't find a reset button, but did snap this photo for you guys. The good news is that it's been working fine since. I didn't do any long term damage to it.
