James Matherly, W0JRM, has written an opinion piece, focusing on some of the silliness of some blog writers, and their lemming-like behavior. A good, quick read. But don’t expect any bright colors or pictures. Go read his piece to find out why.

BLT Construction September 6, 2007

Well, 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.
