With the 3-turns of the main tuning knob to cover the dial, the planetary drive is working! It is a 6:1 ratio which means that it takes 3-turns to go 180-degrees. If it were frozen, then only 1/2-turn would cover the entire dial. 6:1 is a very common ratio for such a drive.</span></div><div></div><div id="yui_3_16_0_ym19_1_1461025613599_3869"> </div><div id="yui_3_16_0_ym19_1_1461025613599_3869"><br></div><div id="yui_3_16_0_ym19_1_1461025613599_3869"><br></div><div id="yui_3_16_0_ym19_1_1461025613599_3869">Not a good ratio for precise tuning but a whole lot better than a 1:1 would be!</div><div id="yui_3_16_0_ym19_1_1461025613599_3869"><br></div><div id="yui_3_16_0_ym19_1_1461025613599_3869"><br></div><div id="yui_3_16_0_ym19_1_1461025613599_3869"><br></div><div class="signature" id="yui_3_16_0_ym19_1_1461025613599_3868">Glen, K9STH </div><div class="signature" id="yui_3_16_0_ym19_1_1461025613599_3868"><br></div><div class="signature" id="yui_3_16_0_ym19_1_1461025613599_3868">Website: http://k9sth.net</div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1461025613599_3867"><br><br></div></div></body></html>
