Yes, all the crystals said 18pF (I take it, that that is all Ineed to know to know what caps I need?)
Also.. I have no scope. How will I see what ones are closer?
Do you have a shortwave radio with BFO?
A frequency counter?
Other than that, you'll have to rely on a carefully constructed software loop that executes a known number of cycles, or a timer routine that divides down the crystal, either way, you then toggle an output pin at some reasonable rate, like once a second, and then count the results over a long time.
You adjust your debugging tools to what you have on hand, or what you can easily get.
