You may want to find a forum about "Hardware Defined Radios"..... :idea:


In any case, here is one relevant link that should get you started: http://www.techlib.com/electronics/crystal.html

That looks to me like a Zener Diode (because of the light blue band). The black band may be perhaps tolerance value?
