I've installed the new roofing filter in my FT1000MP, which necessitated removing the Inrad 70MHz noise reduction mod (_http://www.qth.com/inrad/_ The board goes into the MP without any modifications. It also works in the Mark V with a minimal soldering. Comes complete with nylon standoffs, cable and cap. $35 Shipped CONUS 73 Dwight W9YQ
