Are you using a RS232 cable or a USB to serial cable?

If I go to 17m, and the software is running I can literally hear the serial commands in my headphones. It sounds like tons of clicks, and chirping noises on 17M only. I also hear it on 12m but much quieter.It also shows up on the s-meter as an s-5 pulsing. If I turn off the KXPA100, the noise goes away.
