[Elecraft] KX2 waterfall

[Adam Goler]

Tom, Don,

Thanks! Win4K3Suite seems like a great option. From the video, if I
understood correctly, the MFJ switch splits the sending/receiving paths
such that the SDR play is used as the receiver, rather than the KX2. Is
there any impact to receiver performance? Can the KX2 noise rejection,
filtering, etc still be used? Or does the software do the heavy lifting
there instead?

Will look into trying this out....

Thanks and 73,
Adam KM6PHD
