I have a Westinghouse H-164 AM/FM floor model radio that is missing the AM loop antenna. Does anyone know how many turns of wire it would take to get resonance with the first tuner section?<BR>It looks like the wire was wound around the rear edge of the cabinet.<P>------------------<BR>

Hi D,<BR> Looked at the schematic and picture to this combo unit. The AM circuit uses a loading coil. This coil helps to reduce the antenna length. The picture shows only one complete circle mounted around the rear perimeter of the cabinet.One end of the wire goes to ant. and the other ground. It was hard to tell if there were two turns. You could start with 2 turns and see how it works. If it doesn't, then shorten it too one. Experiment a little to the best reception across the band.<BR>ED<P>------------------<BR>

One thing to help you, the L of the coil which goes as the square of the turns, matters most at the low end of the AM band, so tune in down there (600-700khz)and adjust turns (only)till you get max output. Unfortunately, you CAN tune in an incorrect L at the high end with trimmers etc, leading to a long painful trip into frustration land. so assume trimmers are nearly correct,leave them alone, and match L to an almost full meshed (closed )tuning cap. you will get there!<P>------------------<BR>
