For the time being, the Oat 4.1 site is still on the air (site 2). Because the Oat P-25 site (site 12) has new channels, there was no requirement to do a hard cutover like we did with Hauser last Monday. The Oat P-25 site has been on the air for several months. I don't know what the schedule is for removing the 4.1 site.
