On the KX3 you can turn on the radio remotely. The instructions are on p28 of the manual and say
"To turn the KX3 on, a remote-control system can place 8 to 12 volts DC on the mic jack’s PTT line for 100 ms or longer.”
I use my KX3 remotely two floors up via a Raspberry Pi where I can either run digital programs WsJTX or JT8CALL on and operate remotely via VNC, or I use “ser2net” and run Pignology KX3UI or similar. I haven’t yet cracked send sound over the internet as I mainly use JS8call. Of course PSK31 would be even easier
I set the timeout on the KX3 fairly low, so that if something goes wrong the KX3 will automatically shutdown and can be restarted.
