OK, I've got it.

I note the plug has to be in just more than half way, not all the way for best results. Maybe I should be using a balun, coax, and a phone jack adapter as suggested. But the original antenna was a dipole. So what did they do, ground one leg? I have checked and the sleeve/barrel at the computer is grounded. I'll pull the board and have another look at the traces. I'm sure tip and ring are balanced but we'll just have a look under the hood.... The flat chisel tip did a much better job of transferring heat to the connector lug and hardly any plastic melted this time. The lug heated quickly and the tip drew a film of solder over it. My apprenticeship ended in 1986. I filled the space with hot melt, and applied a little over the connection, then taped it, drew over the braid, and whipped the braid down over the end, with the ends of the braid falling neatly into the groove between the threads and the flange. Then I lacquered the whipping with nail polish. I'll heat shrink over it some day. The boom and therefore the reflector elements are grounded, as they normally would be. I don't know if this does anything. They are grounded from the sheild through a clip lead to a bracket supporting a reflector element. No active amplification is used. It works just great. No rabbit ears, no aluminum foil, and it picks up pointed due east as it should. All 10 FM stations on my dial read the same on the VU meter, all are in stereo, and there is very little noise or interference. Just one thing. There's a cable dangling from the middle of the ceiling. For now, primary Teri can live with this. We will be sharing this whole space soon. Right now I am renting 26 square feet of office space and paying towards the cable modem and fax line. Yours, Doug Goncz ( ftp://users.aol.com/DGoncz/incoming ) Student member SAE for one year.
