Cannot Adjust an IF Transformer’s cores
#27

jr, the reason you haven’t noticed any change when adjusting the primary could be maybe you have the primary directly connected to your signal generator. If that is the way your setup is, then the generator is putting a constant signal amplitude to the primary and any adjustment is getting swamped. If you put some experimental resistance in series with the generator and primary, then as you adjust things the signal is shared between the resistor and the primary and the primary impedance will vary as the frequency you chose varies. Hope this helps!
