The waymark coordinates are taken at the gate into the transmitter building in the middle of this large tower site in a developing area of Coppell. These towers have been here since the 1960s, when this was all pastureland.

"A couple of miles to the west of 1310, Belt Line bends south at the intersection with Denton Tap Road, and right there at the corner (actually reached via a small service road) are the three towers of KLIF (570), one of the very best regional-channel signals in America.
If you've been paying attention to the earlier segments of this story [reproduced below -- BMB], you know by now that the 570 signal is the old WFAA radio, descendant of that unusual WFAA/WBAP shared-time operation on both 570 and 820. This site came into use in the late sixties, when the original 570/820 site just a bit to the southwest in Grapevine was condemned for the construction of the new Dallas/Fort Worth International Airport.
When it first came into service, I'm told, there were four towers here: WBAP 820 at the northern end of the site, then the three 570 sticks to the south. Today, WBAP has moved over to Tarrant County and 570 stands pretty much alone here. Two of the towers are closely spaced; to get the third in frame requires a view from the southern end of North Lake. (And getting that view required parking across Belt Line Road and running across traffic to the other side, whereupon your overly-intrepid editor tripped on a high curb, gouging his hand and cracking the filter on his lens - ah, the lengths we'll go to for tower pictures!)
In any event, WFAA radio lasted just 13 years on 570 once the WBAP share-time deal ended. In 1983, in a last gasp of AM music radio, 570 became classic rock KRQX - in AM stereo, even - for the last four years of Belo Corp. ownership before it was sold in 1987. Then came oldies as KLDD and a year as KKWM, simulcasting soft AC from sister KKWM-FM (97.9), and then the station was sold to Susquehanna to become the new home of KLIF, the heritage calls relocated from their home at 1190. And for 12 years now, KLIF 570 has been doing talk down there at the bottom of the dial."
The earlier installment, as promised: (

"WBAP's move down to Bisbee in the early eighties (the most recent move of any I-A clear channel allocation in America, to my knowledge) ended a long history of sharing transmitter sites with the former WFAA, Dallas on 570. Until the sixties, of course, WBAP and WFAA shared more than just a transmitter site; they shared the 820 frequency (and 800 before that), then added the former KGKO, Wichita Falls (the very first in a long history of Wichita Falls-to-DFW move-ins) on 570 so that whichever station was not using 820 would have an alternate frequency on which to operate. When WBAP bought out WFAA's interest in 820 in the sixties, leaving WBAP alone on 820 and WFAA alone on 570, the stations continued to share a transmitter site between the two cities on land that was eventually absorbed by the Dallas-Fort Worth International Airport.
And even after that site was condemned, WBAP and WFAA continued to share a new site in Grapevine, until this site went up. As a newish site, it has a much skinnier tower than KRLD - but you can't argue with the signal: WBAP has, some say, the largest interference-free U.S. land coverage of any radio station."
