That is a very good question. The setup of a "Home Channel" is only accessible on the mobile devices. On theses devices you can setup a channel to have the Slingbox tune to. This feature is not available on the computer. I am sorry if that causes any trouble but what I could suggest is setting up channel 206 as a "Favorite." After adding it as a "Favorite" you would be able to connect to that unit and than you would be able to change the channel via the Favorite menu. I will post how to setup your favorites.
Hope this helps,
