The opacity of the following occurrences is reduced by the area ratio between the plotted circles.

Display bounces on map

The drawing of the bounces on the path is characterised by :

- The bounce distance, determined by the adjustable parameters (altitude of the reflecting ionospheric F layer), and the radio angle of departure of the waves at the antenna.
- The diameter of the circles is determined by the horizontal aperture angle of the antenna, which can help you to find out what the directivity angle of your antenna represents in beam width on the map

Be cautious not to misinterpret this 2-dimensional representation : Contacts are still possible outside the represented bounce circles!

Stations settings. Move stations by dragging the markers or by entering the locator below.

Stations
MUF & foF2 Short path curves For the short path (shortest path between TX and RX), the curve indicates the theoretical possible frequency range for achieving a long distance contact by bounces of 3000 km.
path is workable & usable frequency bandwidth (MHz)
⭕️ path is poor, not suitable

Curves SP
MUF & foF2 Long path curves For the long path (longest path between TX and RX), the curve indicates the theoretical possible frequency range for achieving a long distance contact by bounces of 3000 km.
path is workable & usable frequency bandwidth (MHz)
⭕️ path is poor, not suitable

Curves LP
Summary table of frequency bands potentially opened for long range communication
✓ the band can be currently used for long distance contact between the two markers
? the band is at the limits but might be tried to make contact between the two markers

Release #3

Here are some new features with this latest version released on April 28th !

The Long path (LP) is now added and connects the two markers opposite the shortest path (SP). It is designed in dotted lines on the map – Thanks to all voter on the feedback platform.
The TX and RX markers antipode (red and blue) points are placed on the map. – Thanks to Pieter N4IP for suggestion
Just as the SP curve tab was, with the LP line, the MUF and foF2 curves take place now under a new tab. The curves are improve with nice gradient colors.
New synthesis indicators are displayed in the SP and LP frequency curve tabs.
New tab in the panel that presents a summary table of frequency bands whose activities may be appropriate for establishing radio contact between the two markers.
Wave bounce zones have been added to the map. – Thanks to David F4HJA for suggestion
Size of the sun reduced. – Thanks to Pieter N4IP for suggestion, and all voter on the feedback platform.
Sidebar Menu improved : General settings take place, with a vertical scroll when needed.
General settings: You can enter your radio call sign (for future use).
General settings: You can disable the display of popups when you enter a callsign in the bottom panel.
General settings: Soon the Win-Test logging software will be able to communicate with HamDXMap. Still under developpement.
On mobile device, sidebar can be closed by clicking outside it
