PC board was from was a group buy. Everything else bought locally or from Mouser. http://www.diyforums.org/. This project gave me an appreciation for the Hammond extruded aluminum enclosures - they're easy to work with and the result is "Professional" DIY. I've used this enclosure twice more now, first with a CAT/digital interface to the FT-897D and again with the FM Stereo Broadcaster.
