transmitter circuits 4
If the audio input is a microphone, it is expected to precede an amplifier to achieve an output power of approximately 8W. The amateur seeking to enhance a small transmitter, which is likely already constructed, can utilize this circuit, which...
LC CHECKER
The circuit operates on the principle of the grid-dip or absorption effect, which takes place when a parallel resonant circuit is coupled to an oscillator operating at the same frequency. Transistor Q1 functions within a standard Colpitts oscillator circuit, maintaining...
100W Medium Frequency Transmitter
The 100W4 is a two-tube medium frequency transmitter designed for pre-tuning to three frequencies within the medium frequency band, supporting emissions types A1, A2, and A3. In the A1 configuration, both tubes function as parallel oscillators. For A2 and A3...
Last-cycle-completing-gated-oscillator
Regenerative feedback at capacitor C allows the oscillator to complete its timing cycle instead of shutting off immediately. The integrated circuit (IC) used was a CD4011AE, although an equivalent IC will also function.
The described circuit utilizes regenerative feedback to enhance...
Electronic Organ Circuit
This electronic organ circuit is straightforward to construct and primarily consists of an emitter-coupled oscillator formed by transistors T2 and T3. A square wave voltage can be obtained from the collector of T3 (X2), which imparts a clarinet-like quality to...
