Re: Operation of K Line Over LAN (Tom Richardson)

[g7ltq]

For reasons of family convenience, I have started to run my KX3 remotely in my Loft using our WiFi Lan from a computer three floors down.

I have assembled a Raspberry Pi 3 in a case with a 7” LCD screen.  The inbuilt wifi on this puts in on my home network.

Using ser2net on the Raspberry Pi, I can run KX3UI on my iMac three floors down ( configured as  a Piglet ).
This is well documented elswhere

I then  set up a virtual screen screen session with the Rasbian’s RealVNC and set the resolution to 1024x800.

I can then run WSJT-X on the remote Raspberry Pi in the higher res screen session upstairs , but see and operate it on my downstairs iMac computer.
I haven't yet managed to get voice over IP for SSB, but if PSK31 or the the JTxx modes interest you then it can be done easily and cheaply.

I haven’t yet setup a remote relay driven by the Raspberry Pi to start the KX3 up. but it should be  an easy job to send a  100msec +9v pulse to the mic input line .   When that happens I can close the loft cover .

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.)
