The KT-100 has been at the heart of my shack now for a while, Kenwood made an AT-300 tuner but that has long since become obsolete and almost impossible to find. As you will see from the picture above there is just one button on the front (And it doesn’t really need to be there if you have a TS-2000 or TS-480. As the rig handles the tuning. other than that there are two LED’s that I think will tell you that everything is working well. One labeled SWR which blinks whilst tuning and then blinks SLOWLY if it can’t obtain a match. The second is Tuning which blinks whilst tuning.
I have found that with my random wires and a 9.1 unun that the tuner will handle just about everything, with my Hustler BTV-8 I have found that there is no need to use it at all, so it runs just the wire antenna’s.

My only comment would be that on tuning its a noisy beast and that You need to keep a little distance between the tuner and the radio. Other than that. I am glad to own one.
