Participate in contests with ease with your QCX. Use N1MM+ to log your contacts and to send signal reports. With the CAT & Key interface you connect the CAT and Key of your QCX with only one USB dongle. I found this simple schematic by Guiseppe IU8EUN, in a post on the QRPLabs group.io forum and decided to make it into a PCB.

The settings that work best for me are the following: Kenwood TS-480, 38400 baud (bps), Parity N, DataBits 8, Stop Bits 1, DTR (pin 4) CW, RTS (pin7) Always off.
