Rich said: >** An L-network always has the lowest Q possible. Is mo' Q mo' betta?< Rubbish. Do the math. The Q is the sq.rt of the impedance ratio -1. So the bigger the impedance transformation, the higher the working Q. In any two variable system, Qw is an uncontrolled variable. A 3 variable network allows Q to be defined. That's the advantage of the T or pi (which is the dual of the T). 73 Peter G3RZP _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
