Hi Rustu,

thats right, you need a 24MHz fundamental crystal. Try e.g. Farnell to order one.

Only for your own experimental usage you can add a resistor in parallel to the crystal (around 1 ... 10kOhms), but the reliability drops dramatically:
On too low value, the oscillator never starts but on too high value the fundamental 8MHz oscillation occur. You must find the right value somehow between.
