Matching 50 ohm to 75 ohm
Most signal generators have an output impedance of 50Ω. To align an FM tuner or measure its performance, it's best to match this to the tuner's 75Ω input impedance
Modifications to the Single Coil Z Match for 1.8 MHz
The original Z Match circuit modified to include 1.8 MHz. The addition of three fixed capacitors and a 4 position switch gives the whole load resistance range at 1.8MHz
