This set of 12 crystals came from a 23 channel CB radio.

They are the solder in type and not the plug in type.

They will work in many other brands of 23 channel CB radios.

11+ MHz and 14+ MHz and 23+ MHz.

They can be used for many experiments or used for making a 10 meter Ham radio or a Freeband CB radio from an old 23 channel CB radio by changing your existing crystals. 

The radio they came from was retired and no longer working.

Sold AS IS.
