Antenna 25 was reporting out of sync when I got back to the AOC. I
don't know if something happened after it was checked, but the T5
switched power looked to be in sync this afternoon (at X-band). I went
ahead and re-sync'd the antenna and reset the DTS modules. Let me know
if you find anything else and I'll take a closer look tomorrow.
