CH 1 , 13.4825 MHz
CH 40 , 13.7025 MHz
26.965 MHz
27.405 MHz
Since all frequencies are obtained from the crystal controlled PLL oscillator, all outputs are
coherent with the crystal oscillator frequency and matching the sample percentage accuracy.
Note that the reference frequency of 5KHz(receiver) and 2.5KHz(transmitter) is obtained by
dividing the 4.5MHz by 900 times and 1800 times
See Table 1 for transmitter/receiver mode VCO frequencies.
