Making VCO for MF-HF-VHF

It is a simple Colpits oscillator, but it has a 78L05 5v regulator (not shown) as the supply feed. The 22K and 33K resistors bias TR1 emitter to about 3v DC, which means that TR1 emitter can feed the CD4040 counter input directly when the synth is fed from a 10 volt supply. This is […]

Booster Antenna

Booster Antenna Circuit Antennas that are much shorter than 1/4 wavelength present a very small and highly relative impedance that is dependent on the received frequency. It is difficult to match impedances over a decade of frequency coverage. Instead, input stage Q1 is an FET source-follower. A high-impedance input successfully bridges antenna characteristics at any […]
