“Direct connect” of a K3/0 to K3s feasible/possible?

[Elecraft mailing list]

Is it possible to connect, using just copper wire a K3/0 to a K3s and forgoing a pair of Remote Rig devices?

The use case is a K3s rack mounted in my house and a lot of cat6 (4x pair of copper) wire running around that is not connected to my LAN.

The K3/0 would be in another room and I’d use a free cat6 to connect the /0 and the k3S. Scenario is CW.

Given it’s last order time on K3 parts, I want to check feasibility of the K3/0 without spending a fortune on the remote rig boxes given my use case is intra house.

Anyone have any ideas or direct experience?

Hi Paul,

In principle there is no reason why that should not be possible.
The remoterig boxes just act as an IP-protocol converter for CAT, audio, ptt, etc.
So without IP in between you do not need them.

Most connections like mic, ptt, key, speaker can be wired directly.
For CAT most probably you have to connect at the RS232 level, so at the K3/0-mini side convert from USB to RS232 and use the RJ45 RS232 at the K3s side.
(mind the grounding of pin 1 in the RJ45 connector, otherwise the CAT data stream is routed to the K3s USB port; see schematics)

When you get CAT going the rest is straight forward.

If this set-up will be free from hum, rf-pick-up, etc. is another matter, depending on the local situation.
