[Elecraft] KX3 & RMS Express - T R latency

[Dave]

Howdy,
I'm using an old laptop to connect my KX3 to winlink system.  Using the
KXUSB for control, and laptop soundcard jacks to KX3 phones and mic jacks.
Works fine, except that RMS Express gives me a Timeout message for T-R
latency - apparently my T - R switching is too slow?  Any suggestions on
what to change to help this out?
Using DATA-A, ALC off
On my old full size rig I used a signalink to interface and I just cranked
the delay knob full CCW which did the trick - since I'm not using the
signalink here I'm at a loss - no easy knob to turn!
Thanks,
Dave
