I notice that some of the remaining three boosters for WLEY 107.9 are reducing Horizontallly Polarized ERP to 26 Watts and leaving Vertical ERP at 99 watts. I assume it is because there was too much area of interference fringes with the H Pol signal with 99 watts, but with more loss of the V Pol signal from the WSCR/WBBM tower, the fringes are less significant. So is it limited to 99 watts due to IF problems with 97.1? That was the argument with translators, that they were limited to less than 100 watts where IF problems might occur, causing signals to be heard all over the dial due to the difference being approximately equal to the receiver IF frequency.

Even though I'm not a big fan of boosters, doing what you described is just one of the common exercises to put more power in one polarity than another. Just more in the effort to reduce destructive multipath effects common with on channel boosters.
Unless there is a lot of unoccupied swamp land or open water where the overlap can be directed, it's a constant challenge to make a booster not interfere with the primary station. It can be done, but takes a lot of time, money, and effort.

I know a perfect site for a booster like you describe. It would hit water about 1.5 miles on either side of a narrow peninsula. There are towers several miles out at the highest AMSL on the peninsula so it can't be NIMBYed. With a narrow beam Yagi and suitable ERP, which might take some experimenting, it would go right into the popuation center, which is in a serious terrain shadow. Hopefully with the right ERP, the fringes would be inconsequential before you hit land on the other sides. If you figure out where, David Eduardo, PM me!
