As someone who files FCC applications for a living, may I clarify?
No competent engineering consultant EVER files an application that doesn't already meet all the FCC's spacing standards. There's no guessing about what those are. They're all laid out in the rules, specifically sections 73.207, 73.215 and 73.213.
If the FCC staff thinks an application doesn't comply with the rules for whatever reason, they'll reach out by email to the consulting engineer to clear up whatever the issue is during processing.
Once the FCC has issued a construction permit, as they did for KJLV, they've certified that the proposed facility complies with the rules.
So if KJLV had any spacing issues to KUIC or any other station, the CP would not have been granted. And because K-Love has some of the best consulting engineers in the business, there's no way they ever would have filed an application that had any spacing issues.
If K-Love isn't following through on building out the CP, it's much more likely that it's some sort of a business issue. Sometimes you file a CP to move just as a negotiating ploy when you have a tower lease that's up for renewal. If you then get a better renewal deal, it's cheaper to stay put than move.
Or it's possible they had some other strategy to move signals around and then decided not to follow through on it for whatever reason.
But again - if there were a spacing issue, it would have been caught during the preparation of the application, and if not then during the application process, and certainly not after the CP was already granted.
I'm not sure how easy it is for Ted on his screen reader, but for any application like this, you can read the entire filing and see how the consulting engineer showed that there will be no interference, at least on paper.
