Update On All India Radio(AIR) Gangtok

As per my latest aircheck, I've not heard AIR-Gangtok on 4835kHz  on January 23rd evening & also this morning i.e.January 24th.Perhaps AIR-Gangtok was not air due to transmitter problem.As mentioned earlier, in this blog  AIR-Gangtok was heard on January 22nd with strong hum on 4835kHz in the morning.

More updates etc soon.

More Updates On All India Radio Regional Shortwave Stations:
AIR Chennai is now hum free and can be audible both on 4920kHz & 7380kHz ( in the morning) here in place.In the evening-night when co-channel station from China is weaker , AIR-Chennai is audible with satisfactory reception on 4920kHz But in the morning the AIR-Chennai is completedly blocked by the co-channel Chinese Regional Station on 4920kHz.

AIR-Portblair is also audible sometimes with fair signal on 4760kHz in the evening-night and sometimes in the morning.
But still here no trace of signal of AIR-Kurseong on 4895kHz & AIR-Aizawl on 5050kHz.Other regional shortwave stations audible here in my place is AIR-Bhopal on 4810kHz & 7430kHz (Morning,day) and AIR-Jaipur on 4910kHz and another AIR-Jeypore on 5040kHz..now the most  consistence reception giving   shortwave station here in my place.AIR-Shillong is audible here but its audio intensity level is at low level now-a-days( low modulation?) and also the audio is also slightly rough.

Radio New Zealand International English on 9890kHz:
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.

KNLS Spanish Feed On English Slot on 15560kHz via KNLS Madagascar World Voice(MWV):
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.
Voice Of Mongolia(VOM) English on 12085kHz:
As per my recent monitoring observation VOM English on 12085kHz  is also facing heavy interference from a  station broadcasting on 12080kHz during its usual transmission from 0900-0930utc.Its very difficult to copy the contents of the broadcast.

AWR Wavescan Not Audible:
And like the previous sundays,this past sunday i.e.on January 21st , Wavescan, the DX Program of Adventist World Radio(AWR) was not audible on its two frequenies 15715kHz (Via KSDA Agat,Guam) & on 17730kHz perhaps via MDC Madagascar  during 1600-1630utc.

All India Radio(AIR)-Chennai With Hum On Its Shortwave Frequencies

AIR Chennai was heard with hum last evening i.e.January 7th here in my QTH Abhayapuri(Assam) around 1306utc on 4920kHz.Perhaps the co-channel Chinese Local Radio Station's signal was weak.And this morning i.e.on January 7th ,no hum was audible on 4920kHz though Strong Signal  Chinese Regional Station was audible.And later in the morning nothing audible of AIR-Chennai  on  another morning frequency 7380kHz.Instead , weak signal of another station with reciting from perhaps from the Holy Koran was audible.I guess AIR-Chennai was off the air this morning during my monitoring period.Thanks Jose Jacob(VU2JOS) of NIAR,Hyderabad, .a keen observer plus monitor of All India Radio Stations, reporting about the sever hum   on AIR Chennai shortwave frequencies  in DX Circles.(I also observed that..I thought it was due to some fault in our domestic AC Power supply system or receiver or other reasons but no such hum audible on other frequencies adjacent frequencies or meter bands...thanks for the information.Usually AIR-Chennai is facing severe QRM from co-channel Chinese Domestic Station on 4920kHz. here in mt location in Abhayapuri in Western Assam.But now-a-days in the evening-night due to weak signal from China the signal of AIR-Chennai can be heard well.But for last a few days..this hum problem began...However I didn't check AIR-Chennai on 7380kHz in the morning for a few week or so)
Here is the video that I recorded as mentioned last evening..
