[Elecraft] Issue with the KX3, KXPA100 and software on 17m...can "hear" the serial commands

[Tom]

It's the USB to serial. 
But like Wayne mentioned there's a fix. 
Thanks

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

Hi I was wondering if anyone else has this issue:

I have the KX3 and the KXPA100 connected through the wiring kit and I am connecting to the combo with Ham Radio Deluxe or Win4K3Suite. 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. 
I have tried a different serial port cable connected to a different port and there is no difference.


It is definitely coming from the KXPA100. I never had this before I installed the amp.




Can anyone here confirm to me if this is just my setup or are other experiencing the same issues?
Thanks, Tom va2fsq
