An Obervation Of All India Radio(AIR) Gangtok on 4835kHz

As per my observation ,All India Radio(AIR) Gangtok has been often heard  with strong noise (hum type) on its shortwave frequency of 4835kHz(morning & evening) now-a-days.And this morning i.e.On December 14th .(2018) around 0123utc on 4835kHz the transmission was noted with free from any hum type  noise and there was music(Ram Bhajan-devotional song in Hindi by a lady) was on air.
Here is the link to the audio recorded:

But later around 0250utc during my air check on AIR Gangtok on 4835kHz , there was strong noise(hum type) and it was difficult to copy the audio contents.Though noise sometime became slighlty less.I understand this is due to some faulty parts in the transmitter.And AIR Gangtok goes off the air for a few days or so and again back on air  with no noise but after a while again the same problem occurs.
Here is the link to the audio recorded around 0304utc of AIR Gangtok on 4835kHz :

Radio New Zealand International(RNZI) English on 9890kHz during 1100-1300utc (effective from January 13th..2018 .Courtesty Alokesh Gupta for updating me about schedule) is facing severe (rather completedly blocked) by a co-channel station perhaps China based Station in unidentifed language.
However  on January 20th..I heard around 1221utc onwards for for 15 minutes or so satisfactory signal of that RNZI English with slight to moderate fading without any co-channel interference with SINPO 45434.But on January 21st, there was heavy co-channel interference there on 9890kHz. as per my aircheck from 1100utc..with time signal..etc plus news from RNZI by a lady perhaps with fair signal..and then RNZI signal was completedly blocked by the co-channel station.

On January 19th, KNLS Spanish Programs was on air in place of regular KNLS English Program from 0300utc on 15560kHz.This has happened on a few  occasions last year.But today i.e. January 22nd I heard regular KNLS English Program from 0300utc on 15560kHz.Previously it was also faced slight to moderate interefence as a form side band splatter  from Chinese based station broadcasting on 15570kHz but now-a-days due to weak signal of Chinese station, no interference was observed.
