When visiting my K3 remote site i want to operate 6M FT8 using the site Win 7 PC. I can use the
Line in/out jacks on the K3 for audio but how to do CAT and PTT?
The COM 2 jack on the RRC remote is occupied by the rs232 cable from the radio and i dont want to interfer with the cabling for the normal remote operation. The COM 1 jack on the RR remote box is not in use. Is there a way to use it to establish local CAT when i am at the remote site?
I cant figure it out reading the manual.

Hi
if you set com1 to mode 6 or 7 in the radio RRC you can connect a PC to Radio-RRC com1 for local CAT control.
PTT can be connected in paralell with RRC PTT oout which is Open Collector

RE your second point:
"PTT can be connected in paralell with RRC PTT oout which is Open Collector"
Pls claify what is meant ...Do you mean in IOSettings to set like this:
IO settings
OUT0 mode =PTT
OUT0 on/off =ON

I now have been successful in setting up local CAT control of my K3 at the remote station. I am using an Elecraft KXUSB cable from COM1 on the RR1258 Remote to the PC. A virtual COM port 10 is created. I am using that port for local rig control and PTT using WSJT-X while I am at my remote.
Com 1 set Mode 7 in Serial Settings. For audio I am using a Behringer UMC202HD interface cabled to the K3 LINE IN/OUT jacks.
The only issue I have is a "slow" PTT. The delay in making PTT is very noticeable but does not interfer with the decoding process. My PC is ancient running Win 7. There is a lot going on I guess with the inception on PTT from WSJT-X and the KXUSB Port and then the radio.
I am wondering about the 1258 OUT0/1/2 settings currently: CONNECT/BAUDOT RTTY45/ KEYER respectively. I have tried changing OUT0 to PTT but it does not "take" when applied.
Is there a solution for the lazy PTT?
