International amateur radio at the radio telescope<\/h4>\n

DL\u00d8EF (“Delta Lima Zero Echo Foxtrott”) has been the international call sign for the amateur radio club station at the Astropeiler Stockert since the founding of the club.<\/p>\n

This is not unusual, as for example, the radio amateurs of the world-famous Arecibo Observatory in Puerto Rico with its fixed 305-meter mirror also used the amateur radio call sign KP4AO. Our neighboring 25-meter radio telescope Dwingeloo in the Netherlands is active with the amateur radio call sign PI9CAM.<\/p>\n

While radio technology in radio astronomy serves exclusively for scientific research, amateur radio is a worldwide radio service. The fascination with radio waves and their possibilities is the bridge between radio technologies for a group of radio astronomy interested club radio amateurs.<\/p>\n<\/div><\/div>

The club station DL\u00d8EF is affiliated with the German Amateur Radio Club (DARC<\/a>), local chapter Gem\u00fcnd\/Eifel (G22)<\/a>. The main activities of the radio amateurs at the radio observatory are focused on radio contests (contests), the maintenance of the historic Morse code (CW<\/a>), electronics tinkering, and courses to prepare for the professional exam for amateur radio (amateur radio license<\/a>). Within the framework of radio technical and operational possibilities, they experiment with high-quality high-frequency measurement technology, as well as with the existing radio astronomical receiving and transmitting options, and accompany and support (field day<\/a>) visitors from interested radio clubs. They are part of the public relations work of the Astropeiler and are active on the regional amateur radio repeater DB\u00d8SE (438.95 MHz).<\/p>\n<\/div><\/div>

In the nearby Sonnenhaus, a shortwave and a VHF station are available. A Windom antenna for 160 m, 80 m, 40 m, and 30 m, and a 3-element beam for 20 m, 15 m, and 10 m are used as KW antennas. For 2 m, 2 x 11 element and for 70 cm 2 x 19 element Yagis are available. We gladly make this station available to radio amateurs upon request for a fee.<\/p>\n<\/div><\/div>

Although the site of the observatory (QTH locator: JO30IN<\/a>) is largely surrounded by trees, if you go beyond that (e.g., with a telescoping mast) or use profitable antennas, the Stockert with its 434 meters above sea level is a very good location for field days on VHF, especially for northern antenna directions. Therefore, we gladly provide a suitable field upon request, toilets, and electricity if desired. However, the highlight of local amateur radio use lies in Earth-Moon-Earth connections (EME).<\/p>\n

On the technical recreational level, radio astronomy is traditionally associated with the amateur radio service. However, radio astronomical activities always take precedence over amateur radio. Therefore, the 10-meter telescope is also used for other celestial observations, and temporary restrictions for actively transmitting radio amateurs may arise during sensitive radio measurements at the Stockert.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
