This circuit implements two logic functions at the same time. The diodes are for general use and the resistors have typical values of 2k2 for logic of 5 V.
With the used coils and the power transistor this circuit amplifies the 5 W of a 11-meter...
The presented circuit generates a signal in the form of a ladder that can be useful for surveying the...
This circuit is from a publication from the 70s. The tunnel diode is the critical component, and...
