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 […]
