WTK/FS- Are these Cb or Ham crystals?
 

Hi All;
I have some small plug in crystals, 1/2"w x 3/8"h x 1/8" thick.
They are all marked with a frequency but I have no idea what they are used in
or good for.
Frequencies are plainly visible in the pics

These are old 23 channel synthesizer crystals for CB.

I am going to make a guess at this.
They appear to be crystals from one of the early semi-synthesized CB
radios (Robyn maybe??) perhaps manufactured around the late 1960's
early 1970's. The early CB's (such as the Johnson Messenger I & II)
needed a receive and transmit crystal for each separate channel. They
developed a process where they could use 10 crystals, as I recall, to
give 23 channel transmit and receive. Of course this is before the 40
channel units became availalbe.
