This is what you need
I have used all methods of interfacing to work all forms of digital modes on HF and VHF. Been doing it since 1983.
Of all of the interfaces this one is my favorite. Recently I built an SDR, the MCHF. I was more than impressed with the fact I could plug a single USB cable into the radio and have the best of all worlds in audio interfacing and CAT control. Everything down one data stream. Well, the SCU-17 gives a person the same ability for their Yaesu rig.
This is a slick little unit. The only complaint I could come up with is that if you're not using the audio raw (you know, using it in the very mode I was just describing) and using the actual "key" line on the radio, the PTT light doesn't work. It's not tired to the SCU-17 when you are using CAT to control the rig. This is a small small complaint. For what this unit gives in return it's way worth the money.
These interfaces are better than using the Signalink because that interfaces has a VOX circuit in it that generated a "key" command using the radio's key line. Now, if you're using a radio that isn't a Yaesu then the Signalink is the best option but for Yaesu, THIS one is.
