for UHF and VHF PLLs and as a baseband clock signal. All RF locals are generated in PLLs.
Due to AMPS mode simultaneous reception and transmission, TX and RX IF frequencies
are exactly 45MHz apart from each other. RXIF is 135.54 MHz and TXIF 180.54 MHz.
RXIF frequency is set so that it is not a multiple of either VHF’s comparison frequency
(120k).
