    It should be possible to extend the freq range in the CPS. I am assuming that the hardware will do it. If you are having VCO locking issues then it will require a mod to the vco to raise the upper lock range.

    In a word no. That is a VHF mid range unit. Typically a radio can only be streached about 10 meg.
