18. Subject to regulation.
19. Max. time after receive enable and the synthesizer has settled before receiver is ready.
20. Image frequency is +4 MHz from desired channel (2 MHz low IF, high side injection).
21. FO = Tuned Frequency, N = Integer.
22. Antenna matching network and antenna will attenuate the output signal at these frequencies to meet regulatory requirements.
