The K3 audio effects options includes Binarual Stereo, this is in fact
I/Q Stereo. If you select this then feed the headphone audio to SDR software that can handle I/Q you can use the the K3 as a narrow-band Front end for software such as powerSDR The amount of bandwidth you can cover this way is of course limited by the DSP filter set on the K3 so try SSB with the widest roofing filter you have I found with my setup I had to, in the software reverse the I/Q channels then all was good. After a bit of fooling around I was able to get a good level of image rejection Is this useful? I dunno, but it's interesting none the less. 73 Brendan EI6IZ -- Don‘t complain.

This -is- interesting. Now if we could get Wayne and Lyle to provide a 11 KHz quadrature ( I/Q ) signal.. Now that would be the ticket. No Softrock required.
