I guess when co-owned 790 and 1510 in Spokane decided to diplex, the 
lesser of two evils was 1510 getting 790's towers 1 and 2 and adding as 
its third a new 179.5 degree tower, thereby making 1510's night array 
165.7, 224.5 and 179.5 degrees.

(KGA's day array consists of the 225 and the 166 degree towers, both from 
790's array).

The alternate, which would have required a little more land to the 
southeast of the 790 array, would have given 1510 165.7, 146.4 and 179.5 
degrees.

But, I think that is a better choice as WLAC would be well protected by 
the 179.5 and 146.4 degree pair, with the taller tower pointing towards 
the co-channel Class A, as is the usual practice, while the primary 
service area would have had the 165.7 and 146.4 degree pair, and the 
secondary service area wouldn't have been destroyed by a 225 degree tower.

As it stands, the 225 degree tower is in both the day and night arrays.
