Folks,

Thanks. Great info ... just what I needed!

I plan to do it to a Courier Royale. It's part of my "Collins Collection"
cuz it has a Collins Mechanical filter in it's IF.

;-)

73,

In my Robyn T-123B 23-channel tube-type crystal-mixing type CB, I changed
the
first two "A" oscillator crystals to 25.325 and 25.385 MHz and ended up with
channels 1 thru 8 as follows:

29.000  MHz
29.010
29.020
29.040
29.060
29.070
29.080
29.100  MHz

There is good info on these rigs at CBC International's website
http://www.cbcintl.com/  under "Crystal Mixing Charts."  For my specific rig
look at
