Samuel,

Relieving mechanical stress on the SXKey is a good idea, but the preferred method is to make a small serial cable extension using ribbon cable with IDE style DB-9 connectors at both ends.  Even though you say your cable is short, the SX can be generating signals up to 75 MHz or so, and running those across loose cables can cause weird problems that will make you think the SXKey is failing.
