[Elecraft] K3 auto transmit - W7RIP

[Bob Wilson, N6TV]

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,
