With the crystal-mixing synthesis CB designs, one replacement crystal 
will give you four channels on ten meters.  I converted a tube Robyn 
T-123B to ten meter AM using two new crystals to get eight channels 
beginning with 29.0 - worked like a charm.

A great resource for this kind of project is the information at


I recently noticed that the solid-state Realistic Navaho I recall from 
my youth used the same crystal frequencies, so I bought one of those 
base stations for a few bucks on eBay and moved the crystals over and 
aligned it.  The transistorized rig is less glamorous, but uses much 
less electricity for 24-hour monitoring of 29.0. Actually it tuned up a 
bit better, slightly more sensitive and about a watt more output.
