Has anyone used a Buxcomm Rascal interface with the K3? If so, what cable does it use? What other interface is used for RTTY and PSK31? I want to do direct keying, not audio, and I want to copy with the 'puter. Does the K3 come with the mating plug for the acc jack? 73, Mike NF4L (It's coming Monday, it's coming Monday)
