It is always very impressive on how a signal behaves with fading. A signal tracer such as the KSDR S meter plug in can show you lines or curves that you cant even believe! Stunning curves that define what we call fading or propagation, can very easily lead you get always into some [very] useful results. Something that one decade ago was rather impossible for the poor man's system.
I m keeping the same formula with the previous posting by adding a screenshot after each reception log which this time is on the MW band only. It is made especially for a rather difficult Facebook group that sticks into the rules rather than the info provided.
KSDR in Hanoi
963 a station 1737 with talks that seem as Viet. mwlist.org shows a station on Thailand which operates till 1700 There is a low level QRM...
Rather flat signal fading in the 7 mins time . a bit stronger flutter in the end of reception.
1008 CNR1 1738 Nice traditional Chinese music and man talking S9
Sue to long distance the signal has more prop disturbances. Look also for the minima and on how signal dropped abruptly
1080 CRI English 1745 S20 talks between two girls about music and emotionalism and how much some songs can hurt hearts . afterwards with a CC pop song
The fading curve is impressively smooth that can mean station is closer than you can think under 1/32 sec resolution Sign off is shown in the right end of the graphic leaving the spots with the local noise!!!
Hungary SDR nearby Budapest
729 ERA Athens with news at 1900 with max S9 in geek about the forthcoming elections net Sunday 7th
Poor signals in the remain 2 freqs : 1008 1404. Nothing on 1305
No info here. What you get from this curve?
In Buharest SDR same frq 1847:
Discussion with the president of a very small left wing party on why people must vote them. This is part of the intra-party treaty that all mass media must offer part of their time for all political parties to self promote.
1006 1404 1305 are not clearly heard.
SDR spot has self overloading problems QRM from 720 Romania Fading graphic is in auto mode and overloads are shown with separate traces above and below the fading curve
I m leaving also you to comment on this curve.
Doha SDR :
1538 Asianet 1818 old Tamil songs in between short songs references in Tamil or same 1825 with adverts , mentioning also radio Carnival , possibly new name? S0+22db max
A bit intense fading level even if the station seems to be in a relatively close distance to the SDR spot. Around 378 km . This can be cause by the mild overloading of station's audio> Notice that signal tracing is also dependent to the decoding modulation!
Don't forget: Propagation is one of the most important factors of any SWLer or DXer. It can kill or even enhance reception on a HF Circuit. I remind you the P or F factor in the SINPFEMO code. Just think why the RSBG and ARRL edited books on propagation!

This will be the only and the one case of making such posts. I will cotinue my older format of text only postings unless i will receive more the 40 replies!
