What items uses a 6.5536 crystal?

Question

I'm looking for a 6.5536 crystal for a "HACK" on a CB radio. You can add a place were they sell them. Please what items uses a 6.5536 crystal.

Answer 1

It's 2^16 * 10^6, so maybe a wall clock. A 16-bit divider would give 100Hz.

Try Digi-Key or Mouser.

Looks like it's also a popular choice for constructing a "Red Box."
