To expand: not much if anything has changed on the non-comm end of the band:
88.5 still all-Swaggart all-the-time
89.3 some time back WRKF dropped daytime local classical for NPR network talk shows, lost some of their charm IMO. BR's only HD radio station.
89.7/91.5 still Rev. Kennedy's ministry
90.3 still smoooooooooth jazz
91.1 still college radio (which is not a bad thing, I find the current iteration mostly listenable)
Some other signals of note:
BR LPFM 94.9 is now gospel
BR LPFM 96.9 is a rare catch, I have not heard them on the air in a year of trying.
Lafayette's 107.9 is now full power on the 99.1/99.1 tower near Breaux Bridge, puts a good hip hop signal into Baton Rouge. 99.1 and 99.9 still the same (country and ac).
SLU's 90.9 playing less AAA in the daytime.
Hammond's 107.1 now country "Kajun 107". I know that they have been that for a while, but having worked at the original Kajun 103 it's still strange to hear WHMD claim it.
Hammond has an LPFM at 107.9. Every time that I've listened all I have heard is ambient "beep-beep tinkle-tinkle" music.
I have buried the lead: as you pass across I-12, be sure to scan the New Orleans signals. Depending long you have been away, you'll be challenged to find what's still the same.
And surely your folks have prepared you for the unGodly amount of traffic we now face post-Katrina.
The food here is still the best around
