5. Headings and propagation

There are three commands in CLX to help you get the best DX possible. These are SHOW/SUN, SHOW/GRAYLINE and SHOW/HEADING. These commands will only work for you if you have entered your personal details.

5.1 Sun

The SHOW/SUN command can be used in three different ways. It can be used to show sunrise and sunset times for a particular callsign, a prefix or a locator. The output of the command will vary depending on what information you give it but will always display the sunrise and sunset times for your location and for the location of the distant end.

Example:

show/sun ea 

The output from this would look something like this ..

5.2 Grayline

The SHOW/GRAYLINE command works in the same way as the SHOW/SUN command. This program however, calculates the dawn and dusk times for a given callsign, prefix or locator. This can be an invaluable aid in deciding when you will have the best chance of getting DX from a specific area or country.

Example:

show/grayline ea

The output from this command would look like this ..

You can see that there is the same information as the SHOW/SUN command, with the addition of dawn and dusk fields.

5.3 Heading

The SHOW/HEADING command works in the same way as the SHOW/SUN and SHOW/GRAYLINE commands but outputs beam headings for a specified callsign, prefix or locator. Reciprocal beam headings are also calculated.

Example

show/heading ea

The output from this command would look like this ..

If the location is over 8000 kilometres away, then the long path will also be calculated.

Example:

show/heading du 

Would output something like this ..
