8. The second type of radio net operation is called Free Operation. Free operation is the
method of radio net operation in which a number of stations are permitted to contact any
other station within the net. In free operation there is no formal control station, however, there
may be a "senior station" which can exercise control over the net if needed. Figure 1-9 is an
illustration of free operation.

Notice the "hump" in the link between stations C and B. This hump is used to distinguish the
difference between link BC and link AD.
