I guess the Gavar technician realized that their powerful 300 kW TX unit doesn_t match proper on the lowest 31 meterband channel of 9300 kHz, so they made a late move +30 kHz little higher on 9330 kHz now.
Both S=9+35dB signals in eastern Thailand remote unit:
9330 even kHz TWR India via Gavar site, 13.30 UT April 1, 1315-1600 UT on various languages during each day of the week different, see nice Aoki Nagoya database list. 300 kW TX and curtain antenna of #238 ITU type, AHR(S)4/8/1.0 mean 4 rows horizontal dipols, 8 lines vertical dipols, 1 = height above the ground in wavelengths HR = a reflector behind.
and a similar service in 31 mb too, came across of 9910 kHz even, TWR India too, also via Gavar Yerevan site, at 13.45 UT April 1st. Awadhi language on Mondays, acc Aoki Nagoya database list, Mondays 1345-1400 UT.
