the back up site is where WNOU and WYXB broadcast from near post road and east Washington.
Hank is a full Class B radio station licensed to Shelbyville. All the Emmis stations are Class B's and are were originally allowed to broadcast at 50kw at 500 feet...that is what WYXB does-sort of via a directional antenna (they had to go slightly directional when they moved 106.7 from Hawthorne site to current sight to protect someone out east). WNOU uses lesser power at about 1000 feet(13kw), the equivalent of 50K at 500 feet. WLHK is using either the panel antenna on top of the WNOU tower at about 1000 feet or another antenna at the top, but at a reduced power...similar wattage to what WNOU is using but dialed back some, as it would be further north and very slightly west of their current licensed sight on Southport road, they have to protect 96.7 in Alexandria, the second adjacent channel. The only real areas affected should be down in the area of Columbus, Bloomington, maybe Martinsville.
The site also houses WFMS on the same antenna as WNOU. Both have full Class B authorization, etc. On the WLHK primary site, Hank uses higher wattage than WNOU or WFMS as the antenna height there is around 700 feet(23kw).
WYXB is down lower on the tower to gain better near field radiation vs WNOU and WFMS who opted for far field radiation to get the far reaches of the TSA, etc. WYXB benefits from higher near field radiation as this provides better penetration into office buildings...the listen at work station.
For more information on this subject and others (along the lines of plate current times plate voltage times transmitter efficiency times antenna gain minus line loss equals ERP) consult a third class radiotelephone operators permit with broadcast endorsement study guide from back in the day when board operators and disc jockeys were expected to know this kind of stuff.
