"there's now a choice for those who can hear the rimshot 107.3 signal."
I doubt Legends is worried, or should be.
First, even though it comes in decently on a premium car radio east of the Genesee, 107.3 can't be heard on a home or office desktop radio anywhere in Monroe County, meaning it might as well be in Timbuktu. WCBS-FM is probably bigger competition for Legends in the workplace, at least in offices with a decent Web connection. But Legends is heard well everywhere in Monroe County (they're on the Warm 101 tower on Colfax St. in the city).
Second, 107.3 sounds llike nothing more than an iPod, or a clone of Jack, and that doesn't seem to be cutting it most anywhere, especially without any live personalities or live information content like weather, news briefs or traffic, all of which Legends has from 6 AM to midnight 7 days a week. Even if you can hear 107.3, there's no reason to prefer it over Legends (which is tweaking its music mix to include more familiar 70s and 80s songs that were hits in Western NY in their time).
Third. Legends has made one good move music-wise from the get-go; basing its record library on songs that were hits on WBBF and WAXC back in the 60s and 70s, and 98PXY in the 80s, songs that were hits IN ROCHESTER when they were new. That's crucial for any oldies station. 107.3 is probably programmed from out of town and based on national research, which may not synch with Rochester's taste in oldies.
Best not to compare any of these stations with WHTT, which is very much driven by what was a hit on KB, WYSL/1400, WGR or Kiss 98.5 back in the day and skews toward Buffalo favorites in both its music and its personalities.
