I have all of the major components I need to finish the tuner project. The roller inductors from Palstar arrived yesterday as did the high current relays that I’m going to use to switch between high / low impedance matching and high / low capacitance ranges. The plan is to assemble the RF deck and prove it operates manually before attaching the stepper motors. Tasks that remain are to sort out the end travel limit switches for the capacitor and inductors and to assemble a relay driver circuit for the PIC micro-controller so that it can switch the relays.

Picture to follow of all the goodies!
