I had a problem with RFI on my PacketCluster node computer a while ago. The
RFI was getting in on a serial port and causing excessive interrupts. The
computer ran slow whenever I keyed my HF transmitter. I suspect the
servicing of the serial port interrupts slowed down the computer. The
solution was to put 6 ferrite beads on the serial cable, and no more slow
computer.
