*** Your PC has a sound card. That sound card is mounted inside the
back of the PC. It will have some receptacles on it, fairly close
together, usually in a line. At minimum it should have  'line input'
which is where you run a jack from the receiver audio output; a 'mic
input' and an output for phones. They should be marked with icons which
should be reasonably intuitive.

The line input wants to see relatively high impedance, and your
receiver probably has a low impedance audio output. Some have both high
and low. I deal with that issue by taking a small audio transformer on
the order of 8 ohms to some value between 1000 and 10,000 ohms to step
it up from the receiver to the PC.

The whatever recording software is used may need to be configured to
take input from the sound card. If you're recording to mp3, depending
on the software, you'll need a record codec. Even if you don't use
Total Recorder, their website ( www.highcriteria.com ) has some good
info and links explaining some of the ins and outs of that aspect.
