FT-991 and Digital Modes

The Yaesu FT-991 transceiver is a relatively new offering from Yaesu. It covers the HF bands, 6 Meters, 2 Meters and 70 cMeters amateur bands and offers All Mode operation on those bands.

After receiving my new FT-991 I wanted to get it hooked up for the digital modes, but the owner's manual didn't go into any details about using the FT-991 in this mode. After some time spent searching the Internet I discovered that the FT-991 actually has a built-in soundcard that can be accessed and controlled by installing one standard USB cable between the radio and your computer. The data signals for CAT control of the radio as well as the data signals controlling the on-board soundcard all travel across this one USB Cable.

Bottom line is this; the FT-991 does not require an interface, like the SignaLink or any kind of level conversion, isolation to communicate with your computer!

Should anyone else be looking for some assistance with getting a FT-991 hooked up to their computer, a short write up containing my notes can be seen here.
