After noticing a very short and weak signal on 2320.9085 MHz, I monitored the frequency over a couple of hours and saw many doppler shifted traces, typical for aircraft scatter. Very soon I copied &#8220;&#8230;9DP&#8230;&#8221;, when a B777 crossed the path and was sure to see OK0ER in JN99DP in the waterfall diagram. At least 4 Airbuses A380 crossed the path one after the other, giving nice reflections.<\/p>\n<p><a href=\"https:\/\/dj5ar.de\/wp-content\/uploads\/2018\/10\/2018-10-22-10_33-4-x-A380-WSJT-X.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-3247\" src=\"https:\/\/dj5ar.de\/wp-content\/uploads\/2018\/10\/2018-10-22-10_33-4-x-A380-WSJT-X.png\" alt=\"\" width=\"1064\" height=\"598\" srcset=\"https:\/\/dj5ar.de\/wp-content\/uploads\/2018\/10\/2018-10-22-10_33-4-x-A380-WSJT-X.png 1064w, https:\/\/dj5ar.de\/wp-content\/uploads\/2018\/10\/2018-10-22-10_33-4-x-A380-WSJT-X-300x169.png 300w, https:\/\/dj5ar.de\/wp-content\/uploads\/2018\/10\/2018-10-22-10_33-4-x-A380-WSJT-X-768x432.png 768w, https:\/\/dj5ar.de\/wp-content\/uploads\/2018\/10\/2018-10-22-10_33-4-x-A380-WSJT-X-1024x576.png 1024w, https:\/\/dj5ar.de\/wp-content\/uploads\/2018\/10\/2018-10-22-10_33-4-x-A380-WSJT-X-624x351.png 624w\" sizes=\"auto, (max-width: 1064px) 100vw, 1064px\" \/><\/a>OK0ER transmits 1.5 W into a slot antenna in 675 m asl.
