Help - DX Path Map

Postby ADMIN » Fri May 30, 2008 4:20 pm

DX Path Maps provide a visual indication of the paths being spotted.
The geomagnetic equator region and sun overlays can offer useful insight into the propagation mechanism involved.

A picture is worth 1,00 words!

  • Maps do NOT work with obsolete browsers like IE5.
  • GoogleMaps does not support long path plots, so all plot are short path.
    This will be a known problem on the 6M DX Path Map when operators are lucky enough to make and SPOT their LP contacts.

The DX Path Map can be configured to your liking with "My Settings".
You can set the default region, plot line thickness, whether markers are shown or not, and for how long the lines will appear for.
Please refer to the My Settings Help for more information.

Above: 2/70/23 Logger. Map Markers Hidden - recommended, if there are many plots, and the map becomes crowded

Above: Map Markers Shown

NOTE: Markers are only available for the first 10 or 20 minutes since a SPOT was made.
After this time, it's considered old news.
Markers are normally available for 20 minutes, but during the busy months of December and January, they are only available for 10 minutes.
This helps prevent the map from becoming too cluttered.

Above: Clicking on a Marker reveals an Info Window with the SPOT information about that plotted line.

Basic Navigation
You can move the map around by using the navigation controls.
Alternatively, and much easier, is to "grab" the map and drag it around.

When hovering above the map, your cursor will change to the hand.

To grab, whilst hovering above map, hold left click down
Image, move to desired point, then release left click.

You can zoom the map in or out.

Map re-centre
Choose a spot on the map and double left-click.

Plotting your spots
Your can plot a basic Short Path line between yourself and the DX you are reporting.

For this to occur three things MUST happen;
1) You must have a VK Logger Operator Info profile with your own gridsquare filled in the appropriate box
2) You must specify the 4-character (or 6-character if known and higher accuracy is desired) gridsquare of what you are reporting.
3) You must "SPOT" your reception report, rather than using the chat window.

What is the correct syntax for a Grid Square?
Example, 4-characters: QG62
Example, 6-characters: QG62LK

No spaces, no hypens, no dashes, no question marks, just plain alpha numeric characters.

Once an origin and destination is known, a line can then be plotted on the map.

Colour Codes - 6M Logger
Red lines are the most current, less than 20 minutes old.
Magenta lines are 20-60 minutes old.
Blue lines are 60 - 90 minutes old.
Green lines are JT65 or FSK Digital QSOs
Yellow lines ------- are TV Video/Audio spots.

Colour Codes - 2/70/23 Logger
Red lines are 2M spots.
Blue lines are 70cm spots.
Magenta lines are 23cm and higher spots.
Green lines are JT65 or FSK Digital QSOs
Yellow lines ------- are TV Video/Audio spots.

For all bands, line opacity degrades with time, and will be invisible after 90minutes.

What is this SPOT business, anyway?
Using the SPOT feature to announce your report offers a highly structured method of data entry.
This then makes it is easy to actually do something with your information... more so than attempting to pull out fragments of usable information from a casual blah blah blah type message in the normal chat window.

But finding the other grid is a pain!
:!: Not really, not if you use the Logger's features.
To find a grid square of another station;

Operator Info database
You can look up the gridsquare of other registered VK Logger users.

Finding Grid Square of other on-line users
In the "Users Signed In" module, sponsors can click on the user, and their grid square will be revealed in the drop-down "Op Info Quick Look-up "module.

Auto Find
Enter the DX callsign in the Spot DX box and click the find icon: Image
The following databases are then searched; Op Info, Beacon and Early Warns.
If a result is found, the Grid Square will be presented to you.
Click on "Use this Grid", and it is entered into the Grid box for you.
It doesn't get any easier than that.

But I don't know my own grid square?
If you can use a mouse, then you can easily find a grid square anywhere on the planet using the "Mapping" feature. It takes seconds.
(Appears down the bottom, on main Logger menu).
Unfortunately, you have now run out excuses for not knowing! :wink:

Want to know more about Grid Squares?
Visit the Annual Gridsquares Table (AGT) information and resources page.

Something to keep in mind...
Because the Maps covers the entire globe, all Grid Squares are considered valid.
If you enter an incorrect Grid Square by accident then it will still be plotted... and it is nigh impossible to error trap this out.
Bullshit IN = Bullshit OUT! :wink:
