I don't have an x6100, but I remember seeing that wfview supports connecting to the new firmware for the x6100. I'm not sure if it only supports radio control or also supports spectrum display like with the icom device. There was a post where someone used wfview to connect to an x6100, and it seemed like it had a spectrum display, but apparently there was a huge delay. If you have one, you could try it out.
