[Elecraft] KX3 --> Want P3-Like Display on a Mac

[Jim Bennett]

Looked around a bit more and perhaps NaP3 may be the way to go. I need to do a bit more research on this. Also looks like maybe LP-Bridge or LPB2 may be needed if I want the KX3 to get to multiple applications. Not sure on that one. I use the Mac version of the KX3 Utility and my logging program is MacLoggerDX (also a Mac app), so LPB2 may have no benefit for me, unless I can find a way for the virtual ports to be split between Win/XP and OS X.

One other thing that I'm concerned about is this "soundcard" issue. Not sure how to handle such things on an iMac. But I'll figger it out! :-)

There would also some (trivial) changes required to remove dependencies on the linux parallel port driver. Not sure if someone has already gone through this exercise yet or not. Otherwise, you would need some basic coding skills to make it work.

Most of the PC SDR applications can then use this to display a waterfall. The I/Q streams don't contain digital data or anything fancy like that, rather they are simple analogue signals. This is why you need a soundcard or other A/D convterter to digitise the signal in order to for the SDR application to process it. It is convenient to have some basic integration with the radio (ie. via the KXUSB or KXSER cable) so that the application can read the VFO frequency from the radio and display appropriate frequency labels on the spectrum/waterfall display, but this is a nice-to-have.
