If 96.9 were to run an urban format, a 5 to 6 share would seem realistic to me. Granted, it would have to be well run and would have to get a portion of its audience from the white and/or Hispanic populations to do that, but urban stations typically can do that if they're not too narrowly targeted. Not sure what you'd have to run to warrant what you'd consider a full-market signal there. One could reasonably make the case that Topeka has too many of those as is. I'd always heard the Booth family, who were generally considered smart operators, regretted moving 105.9's tower from Lawrence to Lecompton to improve the signal in Topeka. Also, with Topeka being nearly 10% Hispanic, I suspect most of that population is Spanish-dominant. Running a regional Mexican format might be able to make similar numbers, though, much like with urban, selling those numbers would probably be a challenge. Although I lived within an hour of Topeka for about four years in the late-90's/early-00's, I only went there a couple times. I drove through it plenty of times, but only actually stopped a couple. There really wasn't much reason to go there if you weren't from there, and it wasn't known for being a place that welcomed outsiders and transplants. I hear it's trying to change that, but I'd have to think it would be slow going.
I forgot about that one. If I remember correctly, Bott runs slightly different lineups on KCCV 760 and KCCV-FM 92.3. I'm guessing 96.9 relays 760. I know KCCV 760 has had a translator at 101.5 for around 10 years, and it got out quite well for what it was. Looks like the translator for 96.9 is on the same tower as KCCV-FM 92.3, which you'll pass on K-10 on your way to Lawrence just past the 35/435 interchange. The tower's on the south side of K-10.
