The following are links to our 1-page crystal charts in Adobe PDF format.  These 36 charts show the mixing synthesis of almost every American mobile and base AM and AM/SSB CB radio ever made that used crystal synthesis. (Plus a few Canadian models.) This includes all the 23-channel solid-state and tube models, as well as most older 3-Ch. or 6-Ch. handhelds or tube type bases that used socketed plug-in crystals.

The charts show exactly which crystals are used in which channel positions.  If you have a "dead channel" symptom or a group of dead channels, you'll quickly see the exact crystal associated with a particular function.  One crystal usually controls a group of 4 or 6 channels, or even all 23 channels in the case of a TX or RX local oscillator or SSB carrier oscillator.

They're also useful for frequency modifications to 10 Meters or elsewhere.  You could either replace specific crystals, or add new ones to expand the total number of channels.

These files are named according to the Ch.1 crystal frequencies and are grouped by AM or AM/SSB models.   If you know which crystals your rig uses you can simply compare that information to this list, then open and print the correct chart.  Under each filename we've also included every make and model known to have used that synthesis scheme.  (Probably will be others!)

For more complete service information you can also try SAMS directly or the manufacturers that are still around. These are listed in detail in our SAMS Fotofacts™ and sources pages at:  www.cbcintl.com/sams.htm    or    www.cbcintl.com/suppliers.htm
