KESO/KKBA Spacing

J

JustinT

I believe that both of these 92.7s are on the newer side; definitely KESO. They have always seemed a bit close together for co-channels -- far closer than the Houston/Corpus Christi co-channels that are often discussed. Is one of these stations grandfathered in, or do they legally meet the spacing requirements?
 
Both stations are class C2 FMs and according to the rules their towers need to be 190 km apart.
KKBA's tower SW of Corpus Christi and KESO's tower south of Port Isabel appear to be right at 190 km apart.
KESO is boxed in. It can't adequately serve the valley from Port Isabel. But it can't move west or it would short space XHAAA 93.1 which IIRC has its tower halfway between Reynosa and Matamoros.
 
That's correct about the spacing to KESO, but both are licensed as 73.215 contour protection stations. That means that the required separation is reduced to 177km, and they clear that by a little over 8 kilometers (around 5 miles). Both are non-directional.

I was thinking the same thing about XHAAA's tower location, but according to the most recent change applications for both KKBA and KESO, the tower actually is in Reynosa.
 
The latest coverage maps filed with Mexican election officials show XHAAA Reynosa and co-owned XHRYS Reynosa and XHVTH Matamoros all halfway between Reynosa and Matamoros, probably on the same tower.
 
XHAAA 93.1 has also downgraded from 100kw to 50kw which would be necessary to move toward 92.7's tower.
Less power but twice as many listeners in the coverage area. No wasted signal in low populated areas west of Reynosa.
 
Thanks for the update, fred. It makes sense, of course, that they would relocate XHAAA and I hadn't checked the latest info from Mexico on it. Now that I have, it appears that the new site (listed as being in El Control TA) clears the required distance to KESO by 4.9 kilometers, just over three miles.
