PI9CAM Lifft Off PI9CAM Without a Dish

That twittered Frederiek Westra Holthe one of the spectators who insisted to keep looking until the first flying saucer above the Dwingelderveld became visible. With that spectacle came an end of a long day. Around 21:15, the dish came loose from the base.

Restoration PI9CAM

Restoration PI9CAMThe dismantling of the dish in Dwingeloo has started. Today, the dish would be lifted only by an error in the calculation of the weight is was not successful. The starting points of weight are not correct and there is more than 40 tons of force needed to be able to lift the dish.

Source: (www.camras.nlThe lift of the mirror is delayed for a few hours. They could not move the 25 meter-wide mirror of the telescope says Andre van Es (Chairman CAMRAS). The dish appears to be heavier. There is always assumed that the mirror weighs 30 tons. With a reserve of 30% would pull the mirror at 38 tonnes in motion to come. But this still seems to sit stainless. There are first extra counterweights invoked to stabilize the crane. Then tonight a new attempt in which the tensile force is increased. My biggest concern is distortion of the mirror and the stability of the goat as the mirror is much heavier than the 38 tons that already takes, says André van Es.

20 meter EME net

2m EME AntennasPlease remember that the 20 meter EME net meets on saturday and sunday on 14.345 Mhz at 1500 UTC during the winter in the northern hemisphere. I start with the antenna on europe.

We need the participation of all possible members of the EME gang to exchange ideas.
Among us we have a vast wealth of knowledge. Individually we are limited.

Please join us on saturday and sunday and share some of your brilliant ideas with those of us who have struggled to become or are learning to become proficient at our passion.

The newcomer may be surprized at what he may have to share and the old timers already know the vast amount of experience they have.

Please! Let’s share that knowledge with each other.

PI9CAM active during the Jamboree

Camras Dish Dwingelo The NetherlandsDuring the Jamboree on the Air, PI9CAM will be active mainly on RX. We will run the WebSDR on 70 cm and on 23 cm. On 70 cm several small 70 cm JOTA stations will try to see their signal on the moon via our WebSDR. We hope to run the system both nights (October 14/15 and 15/16). During the second night we will also be able to TX, so if JOTA activity gets low we can make some EME QSO’s. Look for us on the HB9Q loggers. Team PI9CAM

Update: Nov 26, 2011

The use of the dish in Dwingeloo was a great success during the Jota 2011. You can read the complete article on:
