Notes
1. The RF frequency range is defined by the oscillator frequency range and the intermediate frequency (IF).
2. This is the level of the RF signal (100% amplitude modulated with 11.89 kHz) that causes a 750 Hz frequency
3. Limits are related to the tank circuits used in Fig.19; frequency bands may be adjusted by the choice of external
4. The frequency shift is defined as a change in oscillator frequency when the supply voltage varies from
