The RF frequency range is defined by the oscillator frequency range and the Intermediate Frequency (IF).
This is the level of the RF unwanted signal, 50 % amplitude modulated with 1 kHz, that causes a 1.1 kHz FM modulation of the local
oscillator and thus of the wanted signal; V
oscillator output with a peeking coil using a modulation analyzer with a peak-to-peak detector and a post detection filter of
300 Hz up to 3 kHz.
