It's far easier to protect the abbreviated primary service area of a 
Class B than it is to protect the extended primary service area AND the 
secondary service area of a Class A.

Dallas' 1190 needed five towers, in-line, to protect WOWO, with only 1 kW 
nights.

For 5 kW nights, Dallas needed twelve towers, and then it also had to 
protect Portland, Guadalajara and Tolleson, in addition to WOWO.

Since WOWO's downgrade to Class B, all 1190s are reevaluating their night 
patterns, and some, including the other North American Class As, have 
already effected changes.

As a matter of fact, the Mexican Class A is, under the "Rio" rules, 
allowed 100 kW days, although it remains grandfathered at 10 kW nights, 
although Guadalajara is presently operating 50 kW days and 10 kW nights.

In addition, "Rio" allocated three additional Class As on 1190 in Central 
and South America.

Those also have to be protected.
