On 13th October 2018 DKARS will hold their third VHF-UHF-SHF Weak Signal Day,
at Astron / Camras located near the town of Lhee in the Netherlands
This day aims to bring together Radio Amateurs interested in weak signal communications in order to give an impetus to this activity on the air. In addition to a variety of presentations, ranging from technical subjects to great operational presentations, there is ample opportunity for mutual conversations in a stimulating environment.
This year DKARS have put together an exciting program of presentations. In addition to presentations by radio amateurs there will be a presentation on the new front feed system Apertif which is used in the Westerbork radio telescope.
Apertif uses a focusbox with many emitters next to and under each other by so-called phased-array feed. The final effect is that the total dish antenna can examine a much larger area of the universe, while through a clever combination of the various beams the resolution remains the same compared with a single radiator.
The other presentations are about building your own solid state power amplifiers for 23 cm and 3 cm, and its use in an EME station. The final presentation is about building a multiband Tropo and EME station. In between there is ample opportunity to meet other amateurs and exchange thoughts.
There will also be plenty of opportunity to also show some DIY stuff, so if you’ve had fun building something, then bringing it along will definitely be appreciated. Show what you have built to encourage others.
Weak signal amateurs are those amateurs who like to be active on the VHF-UHF-SHF bands DXing, for contests, for EME work, via tropo scatter and / or aircraft scatter, to DIY on VHF UHF and SHF and research on propagation in which use is made of weak signals.
This day focuses on all amateurs interested in all weak signal modes including CW, SSB, WSJT.
Door Open – 10.30
Programme Commences 11.00
11.30: Presentation by Baldwin Cabin (Astron);
Apertif the new front-end system of the Westerbork radio telescope. This is the new front-end system that is used in the Westerbork Synthesis radiotelescope
12:30 to 13:30: Lunch break,
on a limited scale a tour may befavourable at the DT. Unfortunately due to the moon phase a demonstration will nto be possible.
13.30: Presentation by Harke PA0HRK;
EME SSPA for 23 and 3 cm
15.00 to 15.30: tea break and QSO
15.30: Presentation by Conrad PA5Y;
The construction of a multiband Tropo and EME station
Closure of Weak Signal Day about 17.00
At the end of the day there will still be an opportunity to have a joint dinner at the local Chinese (at your own cost, of course!).
On behalf DKARS we hope for a large turnout, and in addition to an interesting day, also give a boost to the weak signal activity on VHF-UHF-SHF.
During the day there is coffee and tea available and a catered lunch. Participants must therefore pay a small contribution towards the cost. At present the exact cost is clear but the contribution will be about 10 Euros per person. Any sponsors are welcome to make a donation, contact via PA0EHG.
Registration for participation is, as usual, necessary at ASTRON Interested parties can sign up no later than October 1st. This can be done by sending an email to firstname.lastname@example.org and every registration will be confirmed as quickly as possible..
If you come by car, in order to arrnage access to the ASTRON complex, you should also give the registration number of your car.
