Agreed. FM translators are just a bandage to the problem. I tried listening to 1230's FM translator on South Mountain at 93.7 last night and it kept getting stepped on by KRQQ on both the east and northwest sides.
At some point, the selectivity of FM receivers will become an issue here. The FCC has created this problem, and they could help solve it by demanding manufacturers improve the FM receivers currently sold. Of course that would help the hundreds of millions of receivers already in the marketplace.
