I had a similar problem with the Signalink keying my KX3. I don't do a lot of digital work so forgot about it. More recently I bought and built the 4S-Link from the 4SQRP group. Using this and my laptop's soundcard everything works perfectly. The 4S-Link keys the KX3 reliably and provides isolation.
