VFO
VFO, or Variable Frequency Oscillator, is an electronic device used to generate a tunable radio frequency signal. It is a fundamental component in radio communication systems, enabling the user to select and transmit or receive signals across different frequencies.
The VFO operates by generating an oscillating electronic signal whose frequency can be adjusted over a specified
VFOs are essential in amateur radio transceivers, commercial radio systems, and amateur radio equipment, allowing operators
Historically, mechanical tuning using variable capacitors was common, but contemporary designs favor electronic tuning methods for
Overall, the VFO remains a vital component in many radio frequency applications, providing users with a flexible
