0–18 MHz Receiver

This receiver has some characteristics not unlike those of the so-called ‘world band receivers’ from the old days, which could usually receive LW, MW and SW up to about 20 MHz in AM and which were crammed with transistors. Because of the ‘low-budget’ character of this circuit it forgoes a tuning scale/indicator and the design has been kept as simple as possible. Nevertheless, the name 'Mini World Receiver' would not be inappropriate for this design.
In the RF bands up to 30 MHz, the majority of stations can actually be found below 18 MHz. It is possible to make a receiver for this with a relatively simple circuit.
