Right now, I can confirm on a KiwiSDR in Kerala (southern India) that the National Channel of AIR is still on air. The signal on 9380 kHz is very strong with good audio. The // 1566 kHz from Nagpur is quite strong but with a close second station in Kerala.
However, the Delhi channel 1215 kHz is a (strong) empty carrier on the New Delhi SDR of TWR Monitoring. 1566 is also strong in Delhi.
