Visitor info. The Dwingeloo Radio Telescope is located on one of the busiest bicycle routes on the Dwingelderveld and with its 25-meter diameter, the telescope is almost impossible to miss. For passersby there are information boards about radio astronomy next to the telescope. The telescope is open to the public during special national and regional activities. ABOUT THE RADIO TELESCOPE Second life. The Dwingeloo Radio Telescope, commissioned in 1956, is one of the oldest radio telescopes in the world. Until 1998, ASTRON used the radio telescope for scientific research of the Sun and the Milky Way. Due to a standstill, the telescope was damaged by rust, but enthusiastic radio amateurs were able to give the Dwingeloo Radio Telescope a second life. ACCIDENTAL DISCOVERY Accidental discovery. In the early 1930s, radio engineer Karl Jansky of Bell Telephone Laboratories accidentally discovered that radio waves were emanating from the universe.OLD POSTCARDS
An amateur Dwingeloo historian sent us 24 postcards with the telescope, from his collections. The photos show the different eras of the telescope (with monopod, tripod and current focus box), and some photos show the Würzburg radio telescopes that were present next tothe telescope.
POSSIBILITIES OF THE CAMRAS WEBSDR Observing meteors. During our special openings and stargazing evenings, dozens of visitors are interested in observing meteors. This is why CAMRAS volunteers Simon Bijlsma (PA7SB) and Frans de Jong (PE1RXJ) have put more information on the astronomy page for those who want to read it again or want to know more. It concerns four articles: METEORS LIVE STREAM AUGUST 12, 2020 After two previous live stream demonstrations, we provided another live stream demonstration, on Wednesday, August 12 at 20:00 CEST.We did this because the radio telescope is still closed to visitors due to Covid-19 measures.

ABOUT CAMRAS
Anyone walking or cycling on the Dwingelderveld near Lhee in the vicinity of Dwingeloo will see a monumental steel structure at the edge of the forest: the Dwingeloo Radio Telescope, put into operation by Queen Juliana in 1956 and, at that time, the largest radio telescope in the world.CONSTRUCTION
The tower is a 15-meters-high construction in half-timbered form with platforms, stairs and control house. The mirror hangs on two axes at the top of the tower, and can move in vertical direction (height). The typical beak shape at the top of the tower is needed to bring the mirror into a horizontal position. The tower stands on a square frame USE – DWINGELOO RADIO TELESCOPE Using the Dwingeloo Radio Telescope is the best way to preserve it. Therefore, CAMRAS makes the telescope available for use by amateur astronomers, radio amateurs and youth, and for educational, public and cultural activities.ANTENNA BUILDING
Antenna building. Just as a camera needs a lens, a radio receiver needs an antenna. You can easily build your own Yagi antenna to listen to meteors with the use of an RTL-SDR dongle.. The design of a Uda-Yagi antenna is characterized by three components: the actual active part (the dipole) and two parasitic elements; the reflector at the back and a director at the front. ASTRONOMY – DWINGELOO RADIO TELESCOPE Purpose of the Dwingeloo Radio Telescope. The Dwingeloo Radio Telescope was built for scientific research of radio waves from the Milky Way and the universe. As ASTRON no longer uses this telescope for that purpose, CAMRAS gives amateur astronomers and other interested parties the opportunity to experiment in the field ofastronomy.
VISUALIZE RADIO METEORS Click at bottom left at Band: at 2m, then you activate the meteor receiver (143 to 145 MHz). Type in the Frequency field (above Band) 143048.50 kHz. Click on USB (right, in the second white block) to make sure that the receiver is in the correct reception mode, here is thatUpper Side Band).
ACCIDENTAL DISCOVERY Accidental discovery. In the early 1930s, radio engineer Karl Jansky of Bell Telephone Laboratories accidentally discovered that radio waves were emanating from the universe. He investigated interference on transatlantic radiotelephone connections at a wavelength of about 15 meters. He recorded radio noise from nearby thunderstorms. SOFTWARE DEFINED RADIO RECEIVER Software Defined Radio receiver. The days when you had to observe meteors with large complex radio receivers and antennae seem to be over. The development of inexpensive RTL-SDR dongles makes it possible to make a broadband radio receiver in no time from your laptop with which you can detect radio reflections of meteors..

DESIGN AND BUILD
Designing and building the largest radio telescope. Radio telescopes are not very different in their operation compared to optical telescopes: the resolution or detail sharpness of the observation depends on the opening or diameter of the telescope and on thewavelength.

He investigated interference on transatlantic radiotelephone connections at a wavelength of about 15 meters. He recorded radio noise from nearby thunderstorms.
