Land is the problem...when I worked there LBI could not find the land needed for the upgrade..doubt it will ever happen.. it is restricted in moving north due to 102.9 and that's a big issue..moving south puts in the Gulf of Mexico
But there's 103.1 right? Shouldn't that be enough to not interfere with KLTN?
No, absolutely not. 103.1 is even closer to 102.9 than 103.3.
Lol Mr Chuck! I meant if there's a space between 103.3 and 102.9 how much could 103.3 affect KLTN? 103.1 should be enough space to not overlap KLTN!
I understand. However, 103.1 is a 1st adjacency to 102.9 and 103.3 is a 2nd adjacency to 102.9. Just like 102.7 and 102.5 are the same on the other side of the frequency. You can't move it to 103.5, because of 103.7. It's trapped like KNTH is trapped and can't go west, unless two stations (1050 and 1090) sign off and 1070 KOPY powers down. Not gonna happen.
Double post. I had to delete this one.

Ok makes sense but then how are La Raza 98.5 and that translator 98.7 next to each other? I'm lost here!
The difference is that the translator on 98.7 is very low power. 98.5, 103.3 and 102.9 are all 100KW

FCC Part 73 and 74 set spacing between stations of different classes (height and ERP).....translators only being 250w ERP are allowed much closer to high power signals since its unlikely the weaker signal will interfere with the much stronger signal within its protected contour. However, 98.7 is OUTSIDE 98.5's protected contour of 60dbU so that's a moot point...a 103.3 full power Class C is protected from 2nd adj full power from 65 miles min spacing....lower Classes are spaced accordingly. This is to prevent the adj signal from overloading the FM rcvr within the on channel's coverage area...However, if two FMs 2 channels apart were on the same tower, they likely would not BUT that opens up a whole other can of worms with intermod, etc (signals mixing at 200kHz interval).
There are strict spacing requirements for co-channel, adjacent and next adjacent separations. LBI can't find a location that meets the spacing issues for 102.9
