Right Brian, I don't really understand that as well. Maybe it might make sense but I should see how the schematics would be. The 91mhz might make sense to notch out the harmonics of 45mhz if this is the cause of the spur. Apart from the resonances I would look at the Q factor as well.

10pf series with .3uhy - resonant about 91 MHz
47pf series with 5.0uhy resonant about 10.4 MHz
Is this correct?
