[Elecraft] Impossible mission? USB with the 13khz filter for PSK31on Digipan

[ab2tc]

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).
