One of them is quite a special one: <a title=\"Lineartransponder DB0LTG\" href=\"http:\/\/www.ov-g07.de\/index.php\/relais\/db0ltg\" target=\"_blank\" rel=\"noopener\">DB0LTG<\/a> on 1296,745 MHz.<\/p>\n<p>This beacon provides a very stable signal of normally 40 dB, usable for antenna calibration, especially when the sun isn\u00b4t available at night time. On the other hand the beacon is part of a linear transponder located on the Unnenberg near Gummersbach, Germany. The input is in the 432 MHz band and the output in the 1296 MHz band. In my SDR I can even see the noise floor of the transponder next to the beacon.<\/p>\n<div id=\"attachment_671\" style=\"width: 650px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/dj5ar.de\/wp-content\/uploads\/2013\/03\/DB0LTG.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-671\" class=\" wp-image-671 \" title=\"DB0LTG with noisefloor\" src=\"https:\/\/dj5ar.de\/wp-content\/uploads\/2013\/03\/DB0LTG.png\" alt=\"DB0LTG\" width=\"640\" height=\"466\" \/><\/a><p id=\"caption-attachment-671\" class=\"wp-caption-text\"><strong>DB0LTG with noisefloor<\/strong><\/p><\/div>\n<p style=\"text-align: left;\">When talking about the transponder, Rudi, OE5VRL\/5 was the only one I worked on it until now. We had big fun in performing a QSO via DB0LTG in October 2012 when conditions allowed such a crazy test. While performing my daily beacon check tonight, I noticed some SSB signals on the transponder. So I prepared my (poor) 70 cm equipment and set it to the input frequency. My first call was heard and so I enjoyed chatting to the guys who were initially setting up and now using this nice toy every Wednesday night.<\/p>\n<p style=\"text-align: left;\">By the way: The distance from Mainz to Gummersbach is 135 km.
