I'm not complaining! I like how WSB has doubled-down on local programming.Very simple. Cox makes 100% of the money with EVH. They split it with Hannity.
Why should the #1 radio company in Atlanta share any money with iHeart?

680 use to "protect" Silva NC. That station moved to 540 why WCNN hasn't reworked their directional pattern to put a little more signal north and west towards the ballpark I don't know. They got 8 towers to work with.
There is a 680 in Memphis which I assume is the reason for the NW null (including the ballpark), and another in Raleigh which (again, I assume) is the primary reason for the NE null, and which would limit any changes possible due to the move of the 680 in Sylva, which was sort of "halfway" to Raleigh. I suppose 680 might be able to tweak out a little more signal due north or NNE due to the Sylva move, although the Raleigh station is 50kW 24/7 (DA-N). WPTF-AM 680 kHz - Raleigh, NCI heard that at night games at Truist, 680 doesn't work well. Braves baseball is a significant part of WCNN's programming. As for the engineering with directional stations, duplexing on other directional arrays, they are doing amazing stuff. Every directional station I have ever seen (all built before 1970) had precise spacing of the towers. I guess phasing cabinets can be adjusted to make up for "bad" spacing. As class B AM's downgrade to save electric bills, sell land, or not have the expense of maintaining directional arrays, there could be opportunities for some stations to modify their signals enonomically. "Last man standing."
Playing with the pattern with the phasor and power divider--and the know-how to do that--I get that that won't come cheap. Plus lawyers for the FCC red tape. But we are talking about possibly the second-best AM signal in town and the only other one with significant ratings--probably the only other one with ANY ratings that doesn't lean hard on a translator.So here's the reality check against almost any attempt to do anything to improve an AM facility in 2024: what's the return on the investment?
You're looking at tens of thousands of dollars just to engage one of the few remaining consulting firms that can do AM DA work.
In the very best scenario, maybe you can make some tweaks to the pattern using the existing tower layout. That still involves reworking the phasor at a cost of multiple tens of thousands of dollars.
In the most likely case, getting a real improvement would mean modifying the tower layout. Now you're dealing with local zoning and permitting at the cost of tens of thousands in legal fees, and well into six figures if you're reworking the ground system, laying in new transmission and sample lines, erecting new towers...
...and for what return? To reach the three people in the stands at Truist with AM radios following the game? How would that justify an expense into the hundreds of thousands of dollars?
It would be a small change in audience. Raleigh and Sylva are pretty close radially from the transmitter in "North Atlanta". The radial to Silva is 31 degrees, the radial to Raleigh is 67 degrees. There is also a co-channel that needs protected in Williamsburg, KY, on a 2 degree radial. (In the above, due north = 0, due east = 90)The real question, is what can be done with Sylva out of the way while still protecting Memphis and Raleigh? That's where your ROI might break down. It might not be much.
Yeah, I was thinking that re: Cobb because nothing has changed there (at least not recently).It would be a small change in audience. Raleigh and Sylva are pretty close radially from the transmitter in "North Atlanta". The radial to Silva is 31 degrees, the radial to Raleigh is 67 degrees. There is also a co-channel that needs protected in Williamsburg, KY, on a 2 degree radial. (In the above, due north = 0, due east = 90)
Because of those limitations, absolutely nothing could be done for Cobb. You might be able to cover a bit of Gwinnett.
Something I just realized: the ballpark should be getting a decent signal per Radio-Locator (YMMV). Is the issue really coverage or massive RFI at the ballpark?
Georgia Tech had a problem with cell signals at Grant Field, and the culprit was a scoreboard that was spewing massive amounts of RFI. When that was fixed, the problem went away. Prior to that Verizon and others were bringing in portable cell towers on gameday.
The daytime signal is fine at Truist.Roddy, as others have noted the main nighttime null to the WNW is designed to protect 680 in Memphis (WMFS). By the time you rotate some 30-45 degrees CCW towards Truist Park (12.75 miles away from the center of the array), the pattern should be throwing at least 10 KW in that direction. The day pattern uses just two towers for some very gentle nulls; and should be blasting plenty of signal toward Truist.
