WebThe local oscillator must be set to a frequency that will heterodyne the 235 MHz to the desired IF of 452 kHz (typical). This means the local oscillator must be set to 234.448 MHz (or alternatively to 235.452 MHz) so that the difference frequency will be exactly 452 kHz. WebBeats occur when two waves of nearby frequencies overlap and create a new resultant wave. To understand this phenomenon, let us experiment, We will need two tuning forks of close frequencies, e.g. 700 Hz and 705 Hz.
