If you are asking about the audio feed, I don't know anything about it.
If you are asking about the Saltgrass linked repeater system itself, it's still running as far as I can tell. I've been making QSOs through it on my commutes to and from work. Just this morning I heard a ham in Tyler Tx talking with another just outside of Alexandria, La and pulled over and made contact via the KD5KNZ repeater here in Baton Rouge, La. Spoke with a female ham near Hoston, Tx as I drove through midcity Baton Rouge last week. The system is still operating.
