Odd radio need info/crystal mixing chart.

[T23]

I have an older radio (early 70's maby?) and it has an odd crystal linup that I am unfamiliar with, I am also unfamiliar with the name brand it is.

I have searched google many times over can't even find ANY referance to this company or C.B itself.
It has 14 crystals in it, all around 10.xxMhz.

I need the crystal mixing chart for this lineup.

Any ideas?

Radio: Roberts RCB-11 23 Channel

I owned a Roberts 40 channel mobile when they first came out. It was my first new radio. I believe they were sold by K-mart and others like that. Can't really offer more info though.

Are they all around 10Mhz or are 8 around 10Mhz and 6 at 37.6 to 37.850Mhz?

took a second look at the crystals and you got it.

Some are around 10Mhz and some are around 37mhz.

Do you have any idea where I can get the mixing chart for this lineup.

Go to the CB TRICKS web site and look at SECRET CB volumes 1 & 2. There are several pages in each of these books devoted to crystal mixing charts. Maybe these will help.
