Features
- fset value is determined by the 11.31 MHz crystal frequency and is 10.7 MHz for the example. The VHF marine synthesizer in Figure 4 depicts a single loop approach for FM transceivers. The VCO operates on frequency during transmit and is offset downward during receive. The offset corresponds to the receive IF (10.7 MHz) for channels having identical receive/transmit frequencies (simplex), and is (10.7.
- 4.6 = 6.1) MHz for duplex channels. Carrier modulation is introduced in the loop durin.
