As a part of bringing Astronomy & Astrophysics to school students, we have created a Radio Telescope which is portable and cheap (<Rs.10K) to build. We have played around with different antennae - Helix, Dish, Horn, Dipoles - with a set-top box backend and a PC with graphing software to catch radio waves from Galaxies, Black-holes, Quasars, Nebulae, Sun and even Pulsars.
