The most simple way to know if there is propagation on the shortwave

 Last time i explain to you how to use VOACAP but there is a most simple way so see the propagation on the shortwave bands

DR2W is like VOACAP made for amateur radio but he can be use also by SWL between 10 and 80 meter

Exemple you would like to know what is the propagation on 19 meter ( 15100 kHz to 15800 kHz )

https://dr2w.de/dx-propagation/

I am i Europe and i click on 20 meter band, its 19:00 UTC ( 21:00 local time in France )

You can see good propagation with red colors on Africa and Asia

Now i will do the same from North America on 20 meter at also 19:00 UTC

UTC  https://en.wikipedia.org/wiki/List_of_time_zones_by_country

You can see the propagation in North América is only good for USA and Canada

Now you can see the propagation in North America all the day on 20 meter

Click ANIMATION

You will see hour by hour the colors are changing and the red color is the best

At 04:00 UTC in North America on 20 meter

04:00 UTC on USA east coast is 00:00 local time or midnight

SSN 149 is Sun Spot Number

The SN index also SSN or "SunSpot Number" or "number of sunspots or groups of sunspots" testifies to the number of spots visible on the surface of the sun.

The activity is very dense around sunspots and this has the effect of ionizing the layers of the ionosphere resulting in better reflection at high frequencies.

This index varies from 0 to 300.

Below 100, it is rather the low bands 3.6 MHz and 7 MHz that will be operational.

As soon as this index displays the value of 100, we agree that we have good HF propagation conditions.

From 150, the upper bands 24 MHz, 28 MHz and 50 MHz will allow "long distance"

YOU UNDERSTAND ???

Good DX and 73
