===Receiving DX===

used to show sunrise and sunset times for your own station, a
particular callsign or a prefix.

Example:
and you will receive spots automatically.  However, you may wish to
check on spots just posted.  Maybe you wish to see if a particular
band is open or if a certain callsign is active, perhaps a DXpedition.
The command to do this is SHOW/DX.  Without any other arguments, this
command will output the last 10 spots posted.  It is possible to look
at more than this, for example the last 20 or 50 spots, by adding the
number to the command.  You can make it even more specific by adding a
band in either wavelength or frequency, and/or any additional
information such as QSL details.
   
Examples:
 
show/dx
show/dx 5
show/dx 20
 
will show the last 10, 5 and 20 spots received by the cluster
respectively.


Examples:
show/sun


show/dx on 20m
The output from this would look something like this ..
show/dx 10 on 20m
show/dx 20 on 20m


will show the last 5, 10 or 20 spots on 20 metres only.

It is also possible to check for certain callsigns, or fragments of
and
callsigns in the same way.


Examples:
sh/sun 5b4


show/dx g0vgs
would look like this ...
show/dx 10 g0vgs

To post DX you use the DX command.  The syntax is shown below.


Example:
Example:


  dx (frequency) (callsign) (remarks)
  show/heading zl
 
Where frequency is in kilohertz and the callsign is the callsign of
the station you have worked or heard, (ie not your own callsign!).
The remarks section allows you to add information like the operators
name or perhaps a location.  Actually DXSpider will allow the
frequency and callsign fields to be entered in any order.
 
Example:
 
dx 14004 pa3ezl OP Aurelio 599
 
In fact, all the following will give the same result...


dx 14004 pa3ezl OP Aurelio 599
The output from this command would look like this ..
dx pa3ezl 14004 OP Aurelio 599

Headings and propagation

There are three commands in DXSpider to help you get the best DX possible. These are SHOW/SUN, SHOW/MOON and SHOW/HEADING. These commands will only work for you if you have entered your personal details. They use your entered location as a reference, so if you have not entered it or have entered it incorrectly they will not return the correct information.

Sun

The SHOW/SUN command can be used in three different ways. It can be used to show sunrise and sunset times for your own station, a particular callsign or a prefix.

Example: 

show/sun

The output from this would look something like this .. 

sh/sun
Location                              Rise   Set      Azim   Elev
G0VGS  Morecambe, Lancashire          07:08Z 17:39Z  205.3   24.1

and 

sh/sun 5b4

would look like this ... 

sh/sun 5b4
Location                              Rise   Set      Azim   Elev
5B     Cyprus-5B                      04:23Z 15:40Z  244.0   18.8

You can also specify multiple arguments like this ... 

sh/sun gw4veq 5b4ab zs

and then the output would look like this ... 

sh/sun gw4veq 5b4ab zs
Location                              Rise   Set      Azim   Elev
GW4VEQ Brungwran, Isle of Anglesey IO 07:14Z 17:48Z  204.9   24.9
5B     Cyprus-5B                      04:23Z 15:40Z  244.5   18.3
ZS     So-Africa-ZS1-ZS               04:31Z 17:28Z  289.9   41.3
ZS     So-Africa-ZS5-ZS               03:44Z 16:34Z  278.5   32.0
ZS     So-Africa-ZS6-ZS               03:59Z 16:42Z  277.6   35.0

Moon

The SHOW/MOON command works in the same way as the SHOW/SUN command. This program however, calculates the rise and set times of the moon for a prefix or callsign, together with the current azimuth and elevation of the sun at these locations.

Example: 

show/moon ea

The output from this command would look like this .. 

sh/moon ea
Location                        Rise   Set      Azim   Elev  RGain dB
EA     Spain-EA                 08:15Z 20:09Z  257.2    9.5      -0.6

You can see that the output is similar to the SHOW/SUN command, with slightly different fields.


Heading

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

Example: 

show/heading zl

The output from this command would look like this .. 

sh/heading zl
ZL New-Zealand-ZL1-ZL: 7 degs - dist: 11238 mi, 18087 km Reciprocal heading: 355 degs
ZL New-Zealand-ZL2-ZL: 9 degs - dist: 11540 mi, 18574 km Reciprocal heading: 353 degs
ZL New-Zealand-ZL3-ZL: 19 degs - dist: 11634 mi, 18724 km Reciprocal heading: 345 degs
ZL New-Zealand-ZL4-ZL: 34 degs - dist: 11783 mi, 18963 km Reciprocal heading: 332 degs
