External Antenna:Long Wire multistranded Copper wire 75ft long 33 ft height approx.
Place Of Reception:Abhayapuri(Assam)(India) Grid Location:NL56hi
All time mentioned  in  Coordinated Universal Time(utc) 

Date:November 15,2022
Sri Lanka Broadcasting Corporation(SLBC)  External Service Hindi

The audio file link recorded around 0230utc:
https://app.box.com/s/ldc2q8pewtv6quqdup8dsde03zvraov3
Monitor's Special Notes (Khas Tippani)
SLBC Ext. Ser Hindi's  first transmission i.e.0030-0100utc  on 11905kHz  is currently off the air.And another thing I have noticed about the 2nd half of transmission i.e. 0200-0230utc slot  that the program airs old Hindi film songs and programs ends only always with songs of late Kundal Lal Saigal as per my observation for a few years.A rare tribute to a singer from a radio station.And SLBC also aired a special tribute program as a mark of respect to  Melody Queen Lata Mangeshkar  on February 6th (2022) on 11750kHz from 1630utc onwards.

Voice Of Mongolia(VOM) English On 12085kHz during 0900-0930utc
The Same Old Story Side Band Splatter from 12080kHz 
The reception remains the same on VOM English on 12085kHz here.The moderate to heavy interference as  side band splatter from a broadcasting station on 12080kHz during the mentioned time slot prevents me to copy signal of that station.It is on rare occasion when signal strength of that  broadcasting station on 12080kHz becomes weak, you can hear some sort of audio from VOM English.This has been the case for several seasons now.
Here is the audio recordings link of VOM English a t0922utc on 12085kHz on November 15th:

All India Radio (AIR)External Service Nepali 
On 15210kHz , On November 14th,there was no transmission observed during  0209utc  random check on that frequency.
But later around 0233utc,I found strong signal on air and  AIR Morning News In Hindi was on air.
And again on November 15th, I checked around 0200utc ,I found no transmission on that frequency.But later during my another check on 15210kHz from 0247utc .I found AIR Ext Ser. Nepali back on air with strong signal.

My Latest On Medium Wave

All India Radio (AIR) Dibrugarh: 
Recently a news circulated in print media and Television News Channels in Assam,that broadcast of 5 minute Assamese News Bulletin from All India Radio(AIR) Dirbrugarh( which goes on air on 567kHz in medium wave from 1230utc i.e.6PM Local Time) will be stopped from October 25th onwards.And recently while monitoring here at my place of reception during first week of November,I have found that the news bulletin of AIR-Dibrugarh has been replaced  by 5 minutes of Assamese Regional News Bulletin from AIR-Guwahati from 1230utc i.e.6PM local time.And it is for information the reception AIR-Dibrugarh here in my place(In Western Assam) in the early morning hours and from the evening (specially in winter) has been good.And recently one of our fellow ham VU2EHJ set up a webSDR at his location at Sarupathar in Golaghat District and I enjoyed listening to AIR Dibrugarh on 567kHz via this webSDR during day time when It is possible to copy AIR Dibrugarh.I read somewhere that AIR Dibrugarh was one of the most powerful medium wave station of All India Radio network and in 1970s-80s perhaps, it used to receive reception reports from amateur radio operators/radio hobbyists from Scandinavian countries,Holland etc. 
Anyway, this 5 minutes news bulletin in Assamese was started in mid 1997 and I listened to it from time to time.

Here is the audio recording of the opening moment of AIR Dibrugarh relay of Regional News from AIR Guwahati in Assamese (567kHz) on November 2nd  around 1230utc(6:00PM Local Time).:

And I think same program was going on Radio Nepal Kathmandu on 792kHz heard a few minutes later.The signal strength was strong but slightly weaker than Radio Nepal Pokhara.

Sri Lanka Broadcasting Corporation (SLBC) External Service Hindi:
Today it was not heard here during 0030-0059utc transmission however it was heard on the same frequency during its 2nd part of the transmission during 0200-0229utc.But the signal was not strong and slight co-channel interference and also from nearby frequency there.But yesterday on January 4th, SLBC's Hindi transmission was heard on 11905kHz during its first half of transmission with good signal strength.Today morning might be in skip.There was dense fog in the morning and poor visibility.

The audio link recorded around 0059utc:

No signal Of RRI English To India during 0400-0456utc on 1170kHz In B21 Mystery Solved At Last:
it is because now all two frequencies for this transmission slot has been carrying DRM mode of transmission i.e.both 11790kHz  & 
13720kHz.Thanks for the alert message from a radio monitor  friend of Nepal, when he pointed out to the  fact.Later when I checked  the latest  frequency schedule of RRI English posted  I found the fact myself.
And earlier 25mb frequency was used to broadcast the analog transmission and the other frequency used to broadcast in DRM.

Radio Voice Voice Of Mongolia English
0900-0930utc 12085kHz
The reception is usually poor with heavy interference as a form of side band splatter from 12080kHz during the entire period of broadccast.And it is on rare occasion you can hear this transmission with less interference and  atleast a few sentences and a few parts of the broadcast contents can be audible.Today I could copy to some extents of the broadcast.

AIR Gangtok on 4835kHz was not heard today as per my several airchecks from 0232utc onwards upto 0307utc.Perhaps it was off the air during the entire  morning transmission starting from 0100utc.

General Observation Of A18 On Some Regional Shortwave Stations Of AIR:
AIR Kurseong on 4895kHz & 7230kHz,AIR Aizawl on 5050kHz & 7295kHz   are still not on air as per my monitoring observation. 
AIR Gangtok is sometimes heard with strong hum noise completely blocking the audio on 4835kHz and followed by a day's or so off the air and again back with normal audio in this A18 season.It might be due to some technical problem on its transmitter.And also a good news that AIR-Gangtok was recently was heard with good signal on its day time frequency of 6085kHz.

More radio monitoring observations etc soon.

A Few General Observations On AIR Regional Stations On Shortwave:
AIR Thiruvananthapuram on 5010kHz , AIR Portblair on 4760kHz  are not audible/ audible with very poor reception now-a-days.And AIR-Chennai on 4920kHz sometimes audible with weak signal specially in the evening  mix with strong signal of co-channel Chinese regional station.The signal this  summer  of AIR Chennai's another morning frequency on 7380kHz is not very good here often noisy.
And as reported earlier AIR Kurseong on 4895kHz & 7230kHz AIR Aizawl on 5050kHz & 7295kHz   are still not on air as per my monitoring observation. AIR Bhopal is facing severe to moderate  inteference on 4810kHz but on 7430kHz it is audible with good signal with no intereference. AIR Jeypore is audible on 5040kHz more or less satifactory signal specially in the morning.AIR Jaipur is sometimes audible on 4910kHz however not monitored regularly.AIR-Hyderabad is sometimes audible with fair signal on its another morning frequency of 7420kHz with sideband splatter & noise etc.But nothing audible on AIR Hyderabad on 4800kHz due to severe intereference from Chinese Regional Stations.

All India Radio(AIR) North East Update

Here is a few very latest monitoring observations by me.

RX:Grundig Yacht Boy 400 
ANT:Cu WIRE 78' Length 30' Height With COAX LEAD IN 

Geographical Location of Reception Place(Abhayapuri):
Longitude:26º18´20´´North
Latitude:90º37´50´´East

All India Radio(AIR) Gangtok On 4835kHz:
As it was observed previously that All India Radio(AIR) Gangtok on 4835kHz sometime heard with severe hum type noise along with distorted audio due to possible  faulty transmitter parts.But for several weeks as observed my me both during morning hours (i.e.0100-0330utc and also in the evening hours(i.e.1130utc onwards) during my random airchecks on 4835kHz I've found good signal of AIR Gangtok free from any disturbance and have been noted with good audio quality. I was about to post about this latest observation...
But around 1350utc in the evening of July 27th (2018) during an aircheck on AIR Gangtok I found severe hum noise and the signal couldn't be copied at all.
Here is the link to audio recorded...around 1350utc..
https://app.box.com/s/n6tqqa7hsqrn7h3oh2qt353ny6pfsttt
However later during another aircheck at 1453utc , I heard AIR-Gangtok without any hum and with clear audio.And Nepali song was on air that time.
Let me observe  AIR-Gangtok on 4835kHz for sometime.

On Other AIR Regional Shortwave Stations :
It is now the only the 2nd shortwave regional station on air of AIR from the North East Region Of India and the most powerful...And the other one is AIR's North Eastern Service from Shillong..(i.e AIR-Shillong on 4970kHz-morning-evening & 7315kHz- day).But AIR-Shillong's signal often suffers from low intensity audio. i.e.perhaps low modulation level plus slighly rough audio..And sometimes remains off the air for several hours.It was not heard  on July 27th (2018) as per my several airchecks on 4970kHz both in the morning & evening.
And still no trace of signal of AIR-Aizawl on 5050kHz & 7295kHz. And also AIR-Kurseong is still of the air on both 4895kHz & 7230kHz.

More monitoring observations and updates etc soon.

A Few Of My Latest Observations On AIR Regional Stations On Shortwave


Here is a few of my Monitoring Observations on All India Radio(AIR) Regional Stations...on shortwave.
Geographical Location of Reception Place(Abhayapuri):
Longitude:26º18´20´´North
Latitude:90º37´50´´East
Receiver:Grundig YB 400 (Digital Read OUT)
Antenna:Long Copper  Wire(30 ft plus length)..height 20ft Plus  as External  Antenna
Co-axial Lead In
(for all cases)

First From our North Eastern Region...
AIR-Aizawl  is still off the air as I haven't found any signal on 5050kHz ..AIR-Gangtok on 4835kHz is now the strongest shortwave station heard in my QTH from our region.AIR-Shillong on 4970kHz is also audible with improved signal quality.
I observed AIR-Gangtok & AIR-Shilllong going off the air for a day & two or a few hours sometimes.

From Eastern Zone..& North Zone etc..
AIR-Kurseong is still off the air on 4895kHz & ...
AIR-Jeypore on 5040kHz is audible with strong signal in the morning.But sometimes its audio gets distorted. 
AIR-Bhopal is also audible on both 4810kHz & 7430kHz with variable reception.AIR-Joypur on 4910kHz is audible with poor reception.

Another interesting development..From South Zone....
AIR-Chennai is now audible with fair signal sometimes good without any co-channel QRM from Chinese Regional Station on 4920kHz for several weeks.
But AIR-Hyderabad on 4800kHs is still facing co-channel QRM from Chinese Regional Station and is still not copiable.But on 7420kHz in the morning AIR-Hyderbad is audible to some extent.
 The reception of AIR-Porblair on 4760kHz & AIR-Thiruvananthapuram on 5010kHz is not very good as the case usually happens in summer. 

But from a few days AIR-Thiruvananthapuram on 5010kHz is noted here in the morning with fair to poor reception quality.with noise & moderate fading  on 5010kHz.
I observed strong peiodic morse code signal on this frequency from time to time in the morning.
Here is the audio recording link with periodic morse code signal which I recorded around 055utc on July 10th.
