I find ears to be rather useful...

Otherwise, you seem to be demanding a lot of data - are you choosing one to buy, or designing one to build?

You can either get an expencive professional one, create your own, or buy a kit. I have one that I bought from JayCar in Australia, it's an amplifier, but if it's put in a dish or parabola then it works even better. The one I got has a simple on and off switch and a volume nob. One can plug in ear buds and listen. It seems to have a fair bit of white noise, which is annoying, but if you don't turn it up too loud then it's still good.
