A Few general observations of Broadcasting Stations which are heard now-a-days here in my place.
For all monitoring Observations 
RX:Grundig Yacht Boy 400
ANT: 75 Feet Length  33 ft Feet Height 
Multistranded Cu .75sq mm Wire(Approx)
with coax lead in
Location of Reception Place(Abhayapuri)(Assam)(India):NL56hi(Grid Location)

Sri Lanka Broadcast Corporoation(SLBC) External Service Hindi:
The schedule  is 0030-0100*utc & 0200-0230utc on 11905kHz
SLBC Hindi is on 11905kHz  during the first half of the transmission is now audible from 0043utc onwards with faint signal & the signal strength becomes strong after 0046 to 0050utc onwards often.I think it is on skip with us during that time. There has been  slight side band  splatter from nearby frequencies with 10kHz either side of the band from time to time specially towards the end of the transmission.
* The transmission often ends abruptly 4 minutes to 1 minutes earler as observed by me.
And the signal strength and overall reception during the 2nd half of the transmission i.e.0200-0230utc is not very good here.There has been slight to moderate co-channel interference  and also side band splatter is also there.

From Radio Peking ..Radio Beijing,...China Radio International(CRI) English Now CGTN Radio..:
It is now finally learnt CRI's English Service is now renamed itself as CGTN (China Global Television Network) Radio.After I read in a radio blog a post about this, I did check a few CRI English frequencies and I have heard that before every English broadcast you can hear this station Idd  announcement by a male .."This is CGTN Radio....".. followed by news in English..then the feature programs.
I think this is for only English programs .
Here is the audio link of the announcement etc recorded around 0700utc on 17710kHz  on January 26th..

Radio Taiwan International(RTI) English:
The present RTI English skd goes like this 
For South Asia, Southern China 
6100kHz 250kW Tumsai District,Taiwan(ROC) from 1600-1700utc 
For Southeast Asia
15320kHz 100kW Paochung,Taiwan(ROC) from 0300-0400utc
The overall reception of RTI English on 6100kHz has been excellent as per my monitoring observations for time to time this month.The signal strength(QSA) is extremely strong and no noise and no interference as such observed during the monitoring periods.
Here is the audio recording link of RTI English on 6100kHz from 1559utc for a few seconds onwards on Janauary 22nd.
The overall reception of 15320kHz is good to fair.The signal strength is good to fair with slight to moderate fading(QSB) is observed.There is no intereference as such now most of the transmission period after Radio Japan NHK World Japansese shifting its long standing frequency of 15325kHz to other frequency a few seasons back.But from 0355utc onwards slight intereference from a co-channel station has been observed and  and by 0357utc, the interference has been severe and it is difficult t o pick the audio of RTI English for last three minutes of its transmission.
Here is the recorded audio link of RTI English on 15320kHz on Janaury 25th around 0353utc:
and on the other audio link around 0357utc:
Radio Taiwan International (RTI) English used to be a good verifier of reception reports with QSL Cards depicting various aspects of Taiwan.I have received many printed QSL cards from the station.
Here is the scanned version of one such QSL Card (both sides)




Radio Japan NHK World Hindi:
The present schedule goes like this
1430-1500utc on 15720kHz (via Madagascar,250kW)
1530-1600utc on 7565kHz (via Tashkent,100kW)
(The Repeat broadcast )
0059-0119utc  on 6155kHz (via Tashkent,100kW)
(The repeat broadcast of the feature of the previous day)

Here is the link to an audio file recorded around 1448utc on 15720kHz on January 22nd.
and another audio link on the same date around 1530utc on 7565kHz
The link to the audio recorded around 0059utc on 6155kHz on January 23rd.

You can access the reception quality by listening to the audio files yourself.
