Multiband CW Transmitter Engineering Projects The circuit of multiband CW transmitter comprise two transistor (2N2222 and BC547), gang capacitor, coil L, antenna etc. Transistor T 1 is used for proper positive feedback for oscillation where transistor T 2 function as emitter follower. Multiband Transmitter Electronics For You A radio frequency oscillator is at the heart of all radio transmitters and receivers. It generates high frequency oscillations, which are known as carrier waves. Here’s a continuous wave (CW) multiband transmitter for transmitting. Morse code signals in the shortwave band (see Fig. 1). It is Multiband CW Transmitter | Circuits Projects Fig.2 : Multiband CW Transmitter: On reducing turns of the coil (using selector switch S2), the oscillator’s frequency increases because frequency is inversely proportional to inductance. Capacitor C1 couples the signal from the tank circuit to the base of transistor T1 (2N2222).
