Introduction

This page is intended to help in the following microwave modes:

- Line of Sight
- Tropo Scatter
- Rain Scatter
- Aircraft Scatter

Start

You must first locate your home or point from which issued. To do this, move the cursor to the desired position, click on the map and a dialog box appears , select the button . The button allows you to configure the DX station you want to contact. Each time you click on the map will leave the dialogue in case you want to change settings.

Line of Sight

In contact mode this page will help you find positions that find no obstacles to your correspondent by the lift chart that can be displayed between two geographical points.
Moving the mouse over the map will display the locator, latitude, longitude of the mouse position , location DX displays the distance and azimuth between your home and the DX station. Clicking on the button , it will display the profile between the two selected points.

 

Tropo Scatter

This mode consists of the refraction of the signal in the troposphere layer, closest to the ground 11 kms, where more than half of the mass of the earth's atmosphere. Due to the effects of temperature inversions (inversion, high), dense layers of the troposphere can guide signals from one point to another. You can get DX 700 Kms.
Tropo mode you press the icon and map forecasts refractive index.
You must move the mouse to the red zone is the zone of maximum refraction.
Moving the mouse over the map will display the locator, latitude, longitude of the mouse position , the locator from home, the distance and azimuth of this to the tropo area and the location Tropo DX, distance and azimuth if configured .
If you have set the DX location is displayed distance and azimuth between your home and the DX station .
The image refractive index forecast is calculated by 4 layers of 975mb height at 850 mb, this gives a refractive index N. This information is provided by Pascal Grandjean - F5LEN can find predictions, cluster, and other useful tools on its website.
The image scale is generated: the color red is the maximum refractive and purple high.
An article interesaten propagation thus you can read here.

Rain Scatter

This mode is to use the clouds as refractors signal to link posts that have no direct vision and increase the range of transmissions, these storms occur between 2 and 6 kms and is the most suitable band 10 GHz. DX may be up to 600 kms.
The Rains Scatter mode will help you find the azimuth and bering to an area of RS in Spain in order to find a point of dispersion of rain (Rain Scatter).
Moving the mouse over the map will display the locator, latitude, longitude of the mouse position (SCP) , the locator from home, the distance and azimuth of the storm and the DX location, distance and azimuth if configured .

If you have set the DX location is displayed distance and azimuth between your home and the DX station .
Based on the idea of Patrick EGLOFF TK5EP web, a very useful site.
The image is obtained from the precipitation radar 14 provincial (except Canary Islands) of the State Meteorological Agency (AEMET) and cooled with an interval of 10 minutes. The page is automatically reloaded, so the maps, it reloads every 10 min .
The picture shows the lowest reflectivity PPI expressed in dBZ. Represents the projection on the horizontal scanning performed by the radar in azimuth while maintaining high antenna axis 0.5 ° to the horizontal. Radar data is closer to the ground and is therefore best suited to estimate the precipitation that falls on the floor, but also the most affected by orographic blocks. The density scale is dde: . A interesaten article in this mode you can spread the web of the URE of Barcelona and one more technical URE de Barcelona y uno más técnico here.

Aircraft Scatter

Useful information

All functions of traditional Google map available. You can zoom to street level, change the map type, etc. .. All settings (zoom level, position on the map, place of origin and type of map) are saved for the next visit.
The map can be moved by holding down the mouse, the icon will appear.
The zoom can be changed with the mouse wheel or the controls .

The recommended browsers are Chrome and Firefox.
Any comments or bug report is welcome

Many DX and JAS 73s.
