I don't understand why you want 13 kHz for JT65. The system requirements from their webpage are
System Requirements • SSB transceiver and antenna for one or more VHF/UHF bands • Computer running the Microsoft Windows, Linux, or FreeBSD operating system • 800 MHz or faster CPU and 128 MB of available RAM • Monitor with at least 800 x 600 resolution (more is better) • Sound card supported by your operating system • Computer-to-radio interface using a serial port to key your PTT line. Linux and FreeBSD versions can also use a parallel port. • Audio connections between transceiver and sound card • A means for synchronizing your computer clock to UT None of this even remotely indicates 13 kHz needed for operation. The signal seems to be only 400-500 Hz wide. So if anything it indicates that the data A mode on a K3 should be ideal. Using a 6 kHz filter for SSB would give you 4.5 kHz bandwidth on a K3, or eight to ten signals. What gives? 4.39 is the current production.
