I just realized, all the hardware I need for direct saoling is already
built into the PC I'll be using... the sound card has a microphone in,

Hi Raphael,

You stand more chance of measuring the noise of the computer. The
problem with dipoles is they are not shielded from earth (and some
dishes suffer equally - by degree). Try it first with Jupiter, a
known and stable source, which should give you some basis for your
further experimentation.
