Weather Station from ON4LDZ - Zaventem - Belgium
My QFH antenna
|Looks great||The varnish is already done||First contact with a scanner, not very good, but encouraging|
To build the antenna, I have first used the JAVA calculator from Jean-Coppens with the following value.
Design frequency = 137.5 MHz
Number of turns = 0.5
Length of one turn = 1
Bending radius = 10 mm
Conductor diameter = 12 mm
Width/height ratio = 0.44
Ws2Lr - Program used to link WX2IMG to LR
|Loading the background picture||Setting of the radius of the map||Final result with 557x557 dimension and $.dat file are also generated (here only the background)||Loading the composed image from WXtoIMG||Mixing of the composed image with the background with apply of the transparence and intensity level, final result.||Setup window of the Ws2Lr|
* This program can also be used to generate a map with variant radius without a mix of WXtoIMG composites.
Since the 1st
of March 2008
|Here the program on the
It sleeps when all batch processes are down.
|Here the program on the Main server.
It wakes up the NOAA PC.
Turn on the LR server.
