41-280 push button tuning
#2

The core you are screwing in should be a ferrous material. With it all the way in the inductance will be at its maximum and so the frequency will be at the minimum of its range (560Kc). When it is all the way out, the inductance is minimum and frequency is maximum (1700Kc).
