*NOTE:
If the local oscillator internal crystal frequency is a subharmonic of an indicated lowest
order frequency, particularly if a 4-7 MHz crystal third harmonic is coincident with a
spurious generating lowest order frequency slight degradation in the S+N can occur as
some spurious output may be generated and appear as a small
�
increase in the noise level.
