That'll be to the PTT line to power up the KX3, not the Mic input! (Care needed.)
Ser2Net (and similar Linux tools) are very good I find. It's also possible to use Grig to control a remote radio, via Hamlib on the PC (or Pi) at the radio. Assuming of course, that the implementation for your radio in Hamlib is complete and (relatively) bug free. I have controlled my TS870 that way from one side of the shack to the other. There does seem to be quite a lot of LAN chatter though doing that, making it a less than pleasant experience if doing that over the interweb. For audio over LAN on Linux, I've settled on a very lightweight tool "Seren". http://holdenc.altervista.org/seren/ Just take note of what you need to do, to run it on a Pi. It works *Very* well, can provide excellent audio quality, and is true point to point, unlike the behemoth bloat of Skype. (I keep meaning to investigate Seren's text messaging facility, to use as a simple rig control path too. It's all open source, but I have too many "Round Tuits" to shuffle as it is.) 73. Dave G0WBX.
