Here's the Scoop...
No, it's not a cc conspiracy, as suggested below. WTDA is Nortah American, WJZA Saga broadcasting.
About two or three years ago, now, the tower for WPAY-FM fell in an ice storm.
WPAY-FM is a Class C station because the tower is located in Kentucky (Class C territory) even though Portsmouth (and the rest of Ohio) is Class B territory.
Class B stations can operate with a maximum of 50 kw. at 150 meters above average terrain; Class C stations at 100 kw at 600 meters AHAAT.
A few years ago, the FCC created a new intermediate Class C-0 for Class C stations that could not operate (or didn't want to operate) at the full class C
The minimum distance separations from a CO station to other stations is less than for a Class C. And those other stations can ask the FCC to reclassify a Class C station to a Class C-0 if it's power/antnenna height combination doesn't match the minimum set for a Class C.
The FAA refused to allow WPAY rebuild their tower to its original height. WPAY decided to move further south & build a new tower to remain a full Class C station. This created an opening for WTDA to move south (closer to Columbus).
Then PAY changed their minds, and decided to rebuild close to their old site at South Shore, KY (just across the Ohio from Portsmouth). TDA jumped up and down and said that PAY must be reclassified as a Class C-0 channel, allowing them to still move south. In the meantime, WJZA requested the move to Pickerington.
What the FCC did here is to say: 1. TDA--your request for a move based on reclassifying PAY is a new request, and we have the WJZA request. 2. You would be too close to WJZA if we approved both requests, we are going to consider your changed request as a counterproposal to what JZA wants 3. You can't move unless we re-classify PAY, we don't believe we have to do that, so your requst fails.
4. Since you can't move, we don't have to worry about you and can move JZA to Pickerington.
It is likely that this is the end of efforts to move 103.9 further south. They can't move off their channel because nothing will fit.
