Wall-to-wall adverts for very large and shiny transceivers with hefty price ... frequency has moved from 9MHz to 20MHz, and the local oscillator is now an Arduino-controlled clock generator.

In a superheterodyne receiver the desired RF signal is multiplied down to an intermediate frequency (IF) by use of a mixer and a variable frequency oscillator (VFO or Local Oscillator) where there ...

It is based on the heterodyne process of mixing an incoming signal with an offset frequency local oscillator ( LO ... is called a frequency mixer or frequency converter. In a superheterodyne ...

In a superheterodyne radio, a local oscillator is an electronic circuit that generates a frequency based on the desired channel. The output of the oscillator is the channel frequency typically ...

A LO (Local Oscillator) is an oscillator used in superheterodyne receivers which when mixed with an incoming signal results in a sum or difference frequency equal to the intermediate frequency of the ...

Many superheterodyne AM radios use a demodulation circuit designed for 455 kHz. When the listener tunes in a station, an oscillator generates a signal 455 kHz less than the frequency of the ...
