BLT Construction September 6, 2007
Posted by N9IK in : operating, portable, projects, qrp , add a commentWell, I finally got around to completing the BLT – Balanced Line Tuner. It’s not just a balanced line tuner though; it now will tune a coax-fed antenna, and a random-wire antenna, as well as a balanced-line antenna. It was pretty simple to put together, although I had trouble a couple of times, caused by my shakiness. Following are some photos of the building process.
