Jason, I just did a search, and the only place I found this topic was a string I started a while back about CYOW terminal and CYQB terminal and how they couple frequencies and use insets on their radar displays (at the time I had no idea how they did this, but having now seen it in my training, I find it quite facinating and useful).
On another note though, while at the time, someone had explained frequency coupling and insets to me, the question was never really answered by anyone (in that thread anyway) why CYOW's feed was not archived...
