On-line Interactive Maps
If you are planning on a DXpedition, consider adding an interactive propagation
map to your web site (see example). To create
- configure HamCap (set your QTH, year, month, SSN, antenna types, etc.);
- right-click on the map and click on Pre-Compute Maps in the popup menu;
- wait until all maps are computed. Depending on your CPU speed,
this may take from 10 to 40 min.;
- right-click on the map holding the Ctrl button down to open the popup menu
with advanced commands, and click on Generate GIF's. HamCap will create a set of
GIF files, with hourly propagation maps for each band. The maps will be stored
in the \Gifs subdirectory of the HamCap directory;
- download the
HTML script for map browsing, and modify it to match the style
of your web site;
- upload the script and the images to the web server and place them in the same directory.
After the expedition, please search your logs for "VE3NEA" and send me your QSL
if I worked you ;-)
If you have IonoProbe installed on your system, go to the Settings tab
in Ham CAP and press the IonoProbe button. IonoProbe will provide real time
ionospheric indices to Ham CAP, and the prediction will be automatically updated
when the indices change.
DX Atlas adds even more power to Ham CAP. Make sure you have
DX Atlas installed, then press the DX Atlas button on the Settings tab. The area
prediction data will be superimposed on the DX Atlas map, and you will be
able to magnify and scroll the map, and view it in the Azimuthal
and 3D projections.

Ham CAP provides a COM/OLE Automation interface that 3-rd party programs can
use to start Ham CAP, set prediction parameters, and run predictions.
In a typical application integrated with Ham CAP, the user will right-click
on a callsign, and Ham CAP will pop up and display the point-to-point
propagation chart. A sample automation code is provided
in the Programmer's Corner section.
