Radio Astronomy in Singapore

[orly_andico]

I learned to my intense disappointment and disgust that satellite dishes and ancillary equipment are illegal in Singapore.

But, you can do basic radio astronomy with this exact same gear. I was so looking forward to making my own radio telescope for my astronomy course this term. Turns out that's not possible..

So - has anyone tried this? I imagine if one were affiliated with a local uni the task of getting a permit from the MDA would be much easier. Has anyone actually tried to get a permit? too late for me, but might be worth noting for the future..

Hi Orly,

I have been thinking of doing a Radio Jove project. Finally bought a Sony SW receiver (Sony ICF-SW7600G) from AM recently for it. Now got to figure out what antenna to use with it. Will share notes with you.

Hi
I remember during my tertiary days I bought a copy of Practical Electronics (which I established to be Nov 1986 through googling) where a contributor shared a satellite dish design made up of a flat (yes flat, not parabolic!) piece of plywood strategically cut to achieve a particular sensitivity to the desired wavelength. As it was flat, it would discretely be placed on a roof masquarading as a roof panel. The article followed suit with the required electronics and RF components needed to build it. Too bad I have long thrown the issue away. What a waste. The author added that many plants can be similarly used but they are better for TV signals. The banana tree was cited as an ideal TV antenna!

I did think of using a Yagi instead. It doesn't look like a dish..

But not in time for my course work. Maybe next time.

Imagine that...I found the article ! It was Oct 1985 issue of Radio Electronics...
