Found this interval at 1614 preceding 1615 sign on. I've never copied AIR at this time, so this was a surprise. They use this frequency 1315-1530 which is often an easy copy in my QTH, but that's from Delhi while this is from Bengaluru, and on a different azimuth as well (though probably one favorable for Rx here in North America. Fair to good.
