Hi You also may want to avoid an oscillator with much 10 MHz content in it. All sorts of odd things can happen with spurs when you have unplanned stuff on the main reference. Another thing to look closely at is - how much of the radio tracks the reference? On some radios, they don't really lock everything up. You get better performance, but not quite what you would expect.
