If you disabled Serial Enumeration and Modem Control at Startup, as shown by screenshots in this document:
https://bit.ly/FTDItip but the rig still keys when you connect the USB cable or turn on the PC, then you may need to do it again, especially if the cable was moved to a different USB port and Windows assigned a new serial port number, or a Windows Update updated the FTDI device driver. Also, uninstall any CyberPower Home UPS control software, which scans all serial ports looking for a UPS, every time the PC boots, and this will also key the rig, assuming CONFIG:PTT-KEY is set to RTS-DTR to enable computer-generated CW and PTT keying. If not, set it to OFF-OFF 73, Bob, N6TV On Mon, Apr 18, 2022, 3:51 PM Rip R <[email protected]> wrote: > Thanks for the help W0VTT, AB7E, & K6MKF.
