[Elecraft] KX3 AND DIGITAL INTERFACE QUESTION

[Matt VK2RQ]

1) yes you can run SDR in one windows and a digimode program like FLdigi for your KX3 in another.

2) pretty much any USB soundcard/dongle will work for basic digimodes. However, if you want to get something that can also be used for SDR (eg. Using the KX3 I/Q "SDR" output), then you'll need a stereo soundcard with a reasonable sample rate. Something like this will work well:
