Hi

If you take a look at page 55 in the manual, they show you the dumps from both a 10 MHz and a 9.xxx MHz unit. The 10 MHz part gets a 60 MHz oscillator, the 9.xxx gets a 39.xxx MHz oscillator installed on the PC board. Page 25 at the bottom shows the maximum tuning range via digital control to be +/- 1 ppm. Page 32 at the bottom includes a warning about trying to tune beyond the rated limits.
