95.1 works well in conjunction with 98.5; 104.5 would be the more likely candidate, but IHeart seems committed to a format that hasn't performed well for several months.
One to watch could be 94.1: San Antonio is over saturated with CHR/Rythmic oriented formats.
If the 101X upgrade comes to fruition, you might hear Alternative on a more far reaching signal. If the 101X upgrade takes place and if it shows in the ratings (a couple of if's): you might see an underperforimg signal try Alternative.
99.5 KISS has seen a nice ratings upswing: it would be interesting to find out if they would add current music to the playlist if a competitor emerges.
