I wanted to do this kind work for my master's (but never completed it).
But other, more interesting tasks require specialised equipment, with detectors that are suitable for the purpose.
For example, to detect pulsars, receiver must have very fast response (very little integration, which is normally used for detecting transits through antenna lobe, for example), that means it has to be very low noise (perhaps it must have cooled or even maser-type LNA).
This equipment is very expensive (part of the reason is, antennas must be physically big, just like telescopes).

How about setting up a radio interferometer.....instead of one large dish have a series of smaller dishes. Although, the setup for that would cost a pretty penny too....plus its complexity would be fairly substantial.
