Jack,

Thanks for the research - very interesting and it looks like a simple fix to
improve the performance of the K3 significantly. You've got me wondering now
though about DATA-A modes. As the K3 uses the same transformer for line in
your work suggests that the transmit performance will be affected by the
sound card output impedance - worth considering at least.

Cheers,
