XTU is about 5th in market billings, and about 35% behind WBEB.
There are around $14 million country dollars in the market, based on a station being just inside the top 10 in 25-54 on average (in Jan-Feb-Mar averaged they were 12th in that demo).
If there were two stations, it is likely that the billing would be split, and neither station would be in even the top 15 in the sales demos; that would mean that the country revenue would decline, and there might be $10 to $12 million split between two stations. And then there is the considerable revenue loss that accompanies a major format shift where few, if any, advertisers would carry over.
The only iHeart station that is so revenue challenged that billing $5 or $6 million a year would be a gain would be low-billing WRFF.
Clearing Bobby Bones is not an automatic revenue source; music based morning shows are sold based on delivery, not clearances.
