Satpc32 and SmartSDR interference

Does anyone else see this issue?

I discovered last night that when I turn on control (C+) in Satpc32 to control both slices that I get interference, you can see it and hear it on the radio.. anyone else seeing this?

Puzzled as to how a program sending commands to a virtual COM port (two of them) would cause interference on the Radio?

So testing this morning, it's even worse then that.. just starting Satpc32 causes it.. top, receive slice, satpc on in, then turned off.. you can clearly see the line.

I believe I found part of the issue, the USB cable from the Computer to the Rotor Control box (ERC-USB installed inside) seems to be emitting the interference, moved the cable and put the last feritte choke on the computer end of the USB cable and it seems to have diminished quite a bit..

Anyone have a good place to purchase ferrite chokes for USB cables??  hihi

Thanks
