So the improved Doppler correction is working smoothly as can be seen and heard in the signals received.<\/p>\n<p><a href=\"https:\/\/dj5ar.de\/wp-content\/uploads\/2015\/09\/2015-09-05-09-51-15-PA3FXB-in-JTMS.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-2107\" src=\"https:\/\/dj5ar.de\/wp-content\/uploads\/2015\/09\/2015-09-05-09-51-15-PA3FXB-in-JTMS.jpg\" alt=\"2015-09-05 09-51-15 PA3FXB in JTMS\" width=\"663\" height=\"302\" srcset=\"https:\/\/dj5ar.de\/wp-content\/uploads\/2015\/09\/2015-09-05-09-51-15-PA3FXB-in-JTMS.jpg 663w, https:\/\/dj5ar.de\/wp-content\/uploads\/2015\/09\/2015-09-05-09-51-15-PA3FXB-in-JTMS-300x137.jpg 300w, https:\/\/dj5ar.de\/wp-content\/uploads\/2015\/09\/2015-09-05-09-51-15-PA3FXB-in-JTMS-624x284.jpg 624w\" sizes=\"auto, (max-width: 663px) 100vw, 663px\" \/><\/a><\/p>\n<audio class=\"wp-audio-shortcode\" id=\"audio-2106-1\" preload=\"none\" style=\"width: 100%;\" controls=\"controls\"><source type=\"audio\/mpeg\" src=\"https:\/\/dj5ar.de\/wp-content\/uploads\/2015\/09\/PA3FXB_150905_095115.mp3?_=1\" \/><a href=\"https:\/\/dj5ar.de\/wp-content\/uploads\/2015\/09\/PA3FXB_150905_095115.mp3\">https:\/\/dj5ar.de\/wp-content\/uploads\/2015\/09\/PA3FXB_150905_095115.mp3<\/a><\/audio>\n<p>PA3FXB in JTMS received by DJ5AR via ISS Bounce.
