[Elecraft] KX3 as Remoterig controller - need success best known method - currently not working for me.

[Oliver Dröse]

Hi Jim,

although I have a KX3, too, I never tried to use it as a control head 
for my remoted K3, the K3/0 mini is doing the job just fine. ;-) But if 
I remember correctly Wayne stated back then that the limited control 
features he put into the KX3 only use normal serial commands/protocol 
while the K3/0 + remote K3 + Remoterig all use a special high 
performance serial protocol. Thus you have to set mode "14 Elecraft 
Twin" on the RR controllers if using the K3/0. For using the KX3 as a 
control head I'd assume you would need "4" instead on *both* sides just 
like normal CAT control. Have you tried that? Just an idea ...

I need someone who has success with this and can pass along some suggestions for success.  I can only find a 2012 posting from SM0JZT where he got it to work:  https://groups.yahoo.com/neo/groups/KX3/conversations/topics/14433

>     - Removing the K3/0 from the equation,  I can change the "Radio Settings - Program Mode" in the remoterig configuration (control and radio ends) from "14-Elecraft K3 Twin" to "4 - Yaesu, Kenwood, Elecraft".  This gives me the "connect" button so I can turn on/off the K3, and it allows me to control the remote K3 with software like N4PY or Win4K3Suite.  Work great and I have full control of the K3, but not having a true VFO knob is a bit troublesome.
> KX3 Control Unsuccessful:
>     - Reverting the settings back to "14-Elecraft K3 Twin", putting the KX3 into "rig control" mode and hooking up a homebrew RS232 cable, through a null modem adapter, to COM2 of the remoterig box... the only control I seem to have is power on/off of  the K3.  VFO, Filters, mode, AF, etc don't seem to be working.  The homebrew serial cable I am using is:  http://eksfiles.net/2013/12/roll-your-own-serial-cable-for-the-elecraft-kx3/ and I am using a null modem adapter dongle between the cable and the Remoterig box.  I think I have tried every other option of "program mode" on the remoterig, but I need to go back and verify the "4" setting on the control and the "14" setting on the radio at was mentioned in SM0JZT's yahoo group posting.
>     - I am running a late mode KX3 and Remoterig with the latest firmware on both (AFAIK).
> So...  Any thoughts?   Has anyone tried this recently?  If you have this working, what are the COM settings for the radio/control side?  Is there something special needed for the null modem adapter?  For the K3-K3 twin setup the remoterig manual shows RX and TX swapped, but also shows RTS/CTS swapped (normal null modem hookup).  Of course with the 3 wires of the ACC1 of KX3 there are no RTS/CTS available.  Should I short these or do something with them in the null modem adapter?  Lots of questions... hopefully someone has an answer!
