3.8.4 VHF/ UHF Programming Example
Frequency required: 465.5MHz
Channel spacing: 12.5kHz
Synthesiser offset: 21.4MHz
The Local Oscillator frequency is therefore: 465.4 – 21.4 = 444.0 MHz
Dividing the LO frequency
by the channel spacing of: 0.0125MHz:
444.0
= 35520
0.0125
This is an integer value, therefore it is OK to proceed.
