After last weeks „Kjetil-Event“ I feel motivated to blog again at DFS / radar events. As I described in older blogs I focus my radar hunting to weather radar systems because these are up today the only radars I was able to capture. Worldwide we talk about the following 5 GHz effected channels 120 / 5600 MHz, 124 / 5620 MHz, 128 / 5640 MHz.
What was the „Kjetil-Event“ ? Our WLAN Pro colleague from Norway testet his new Aaronia SpecAn at his place and found a radar sample at his house and tweeted about it. I wanted to recall the Norwegian weather radar stations and had to look for the correct EUMETNET weblink again.
To have it at a handy place for future recalls I want to publish the link here:
This website publishes the locations of weather radar stations who put their resources together to a European network. This makes it a great and handy resource to locate a weather radar station near you in Europe to validate your DFS event alarms. So I guessed the Hurum weather radar little south of Oslo where the station Kjetil detected in his house. See location of the weather radar stations in Kjetils region little south of Oslo below.
The Hurum radar is the only station running at 6620 MHz (ch 124). It has shortest distance to Kjetils place. All other south Norwegian stations run at 6640 (ch 128). If you play with the country filter at the website you will see the stations in south Sweden run at 5605 (ch 120).
Kjetils place is the first location I heard of where the SpecAn proved validation took place around 20 km away from the radar station. So it is probably the radar antennas main sector who hits Kjetils place. The antenna is described with a 1 degree beam. Getting a hit by this narrow beam at ground level may not happen very often. That’s why I call it the „Kjetil-event“ now ;-).
Kjetil captured the radar event with his labs Cisco environment and proved with spectrum analyzers from Aaronia and Ekahau (Sidekick 1)
