Hi Paul http://lists.contesting.com/_topband/1997-01/msg00037.html You posted the comment from W8JI on a reply sorry about that. . No biggie.
What the patent number? I would like to read more about it. So what different bout your tuner, is it like the ATR-10 design? These transmatches these days T matches just do not have the balls for 160M running power. I melted down a MFJ 998RT arced plates on an MFJ 989B melted down a 25uH Millen coil, arced wire burned up insulation all with 500 watts :-) I tried different configurations. Short 99 foot inverted L does give me a challenge. 0.175 plate spacing arcs over. 0.25 spacing on caps is needed or vacuums variables which are not in my budget. Capacitor L match ARC over. Vacuums variables or open air variable caps with 0.25 inch spacing is needed for 300 watts or better. Inductive L match has heat and at times enough heat to melt spacers on a Millen coil. Who makes a tuner that can take this abuse? -- Jim K9TF _________________ Topband Reflector
