Yup, RFI is a pain. Just moved into new area and live near an electric rail track and when some trains go past, I'll just go off and make a tea. Grounding and bonding is my next task to do for the shack. That will be a challange, not allowed to drill holes in walls for the earth/antenna So I use a window pass through for antenna cable. Unsure how to do earth for shack. Apart from hanging earth out of window. Thanks for sharing anyway. Good luck. 73
