That radio should be able to directly drive a sound card line input. Just make yourself a shielded cable.

Sound card based decoders can do a far better job than slicers (e.g. filter noise and compensate for non-linear responses, etc.)
if the audio is properly coupled to the PC's audio input.
A direct connection (or the near direct connection that a 10k resistor provides) from a tap point to a mic input will overdrive the PC's audio stages and reduce the effectiveness of filtering software. Lack of a DC blocker putting mic driver voltage back into the scanner is another no-no.
A direct connection from a tap point to a PC's line input can put an excessive (600 ohm) load on a scanner's audio detector stage and lead to signal distortion. The high load pretty much guarantees that there will be poor low frequency response issues.
With simple two level signals (like Moto 3600 bps CCs), mediocre audio coupling generally isn't a problem as long as you're monitoring strong local signals. But when the static and other noises increase, a dicey audio link will surely lead to lower than necessary decoding rates.
