All the TV and FM "protected contour" maps should now be fixed. After the Tiger mapping service was shut down, the FCC only had the images it had cached on its own servers. After they rolled out the Google overlays I figured they'd keep the old images around for a while — I was wrong. The TV maps disappeared immediately and the FM maps disappeared earlier this year.
Some of the early Google map links were broken directly from the FCC. I got some of them during this updating session but there's no doubt some slipped through the cracks. Otherwise, everything should be working again. If you find a bad link, mistake or whatnot let me know and I'll get it fixed.
I've also standardized and added auxiliary information to those FM stations that have such facilities. There are only 15 FMs in the state that have filed for auxiliary backup transmitters, and a few others scattered in New Orleans and Pensacola. I don't know much about them but it appears that having a licensed backup site allows a station to switch to the backup without notifying the FCC immediately, versus having to apply for an emergency Special Temporary Authority.
Tuscaloosa station WTXT no doubt is glad they paid to get the aux license, as their main tower was felled by winds or a tornado during the recently outbreak. Their auxiliary facility is located on the old WACT-AM/FM stick between Greensboro Avenue and I-359. That site was just a few hundred feet from being in the middle of the tornado that ripped through Tuscaloosa!
