The 2nd IF is 15kHz which is well within the capabilities of many sound cards. But it would require surgery to the K3 as this signal is not available externally. It would certainly be an interesting experiment for the bold risk taker. Most PC SDR software needs an I/Q pair of signals which this is not, but there is software that will take a single signal elevated above baseband (I believe Softrock works this way).
