[Elecraft] [KX3] ADC/DAC access, keyer input

[Christian KJ4VPK]

? If the SDR in the KX3 is presenting analog stereo I/Q why can't this be simply USB to make the KX3 look like an external sound card to present the same I/Q as an all digital path to the USB host (PC). No need for outboard SDR, we aren't talking about IF.

Which is why you don't want the I-Q created by an outboard box, you want to
get it out of the KX3. And that's just what the Elecrafters have done for us
in the KX3's design, in response to requests from those who now have
outboard SDR boxes.
