Need some 139xlr older info.

I know you can do the pll upd858 mod for extra channels.
I see there was an expo Kit Q for the radio.
I'm trying to find what that kit did.
Was it toggle switch kit
Was it an Expo 100 Kit with crystals if so what was the frequencies of the kit?

thanks

I think the Q kit just manipulated the PLL for extra channels.
I see no crystals in the image below.
