Circuit electronics Carrier Oscillator

Carrier oscillator is a crystal controlled oscillator using two numbers of BC548. The circuit does not use any coils or turned circuits. First BC548 is used as oscillator second BC548 is used as buffer. The carrier oscillator frequency is offset by 1.5 KHz above ladder filter (IF) frequency. The carrier oscillator frequency can be varied […]
