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 http://www.myradioroom.com/13xtals.jpg http://www.myradioroom.com/10xtals.jpg Make me an offer if you want but E-Mail to :-) Thanks es 73...........RICH-WA2RQY Web-Page URL HTTP://members.aol.com/rlucch2098/index.html |

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.
