----------------------------- My point is that the dial mechanism is a simple form of mechanical logic. When the operator tunes a an SX-28 so the index points to 10.000 MHz, the operator is "requesting" that frequency. The operator isn't setting the L/C network to anything he/she can see or identify at that point other than to make the index point to 10.000 on the dial. The dial mechanism moves the tuning circuit components in a way that, if the system is calibrated, will result in the receiver being tuned to 10.000 MHz, plus or minus whatever errors are inherent in the calibration or pointing accuracy of the mechanical computer (dial mechanism).
