locked Re: Suspect RFI into computer


most likely your RFI is hitting the USB interface between PC and TRX. You should use a USB cable with double shielding and RF chokes an each end. If this does not solve the problem try to connect the shield of the USB connector at the PC side to the tuner chassis by means of a ground clip which is common for scope probe tips. My TX power can now go up to 500 W without affecting the (notebook) PC.
