[Elecraft] Operation of K Line Over LAN (Tom Richardson)

[Dave B]

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".

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.)
