I have the FT857D and it's a great radio, but the screen is on the small side. Here is a video by OH8STN on the FT817 the setup works on the FT857d also, i purchased the bluetooth module and downloaded the software and it works pretty good and now i have a larger screen.
picture of my tablet.
I've used that software before, only just as a web sdr. But I did notice it was set up to control the 817/857. Pretty cool!
