Hi dear OM,

I am searching for some info especially how to change the frequency of my surplus  CTI DRO Oscillator ( see picture ) as the present frequency does not fit to the normal i.f. like 144 , 432 or 1296 MHz. when using this oscillator for some higher microwave band. The present frequency is 12,5755 MHz. How to open this oscillator without destroying it ( maybe those bigger three screws Verbaasd ) ? And what is the possible frequency range when changing the x-tal and what is the frequency range when tuning the DRO screw ?  Allthough surfing some hours with keywords like ODU , Endwave or CTI DRO oscillator I found no info.Many thanks for all possible hints in beforehand !
Best Regards
Wolfgang, DD8BD
