Thanks Steve! I'll look into that as well.

 Steve COR or actually RUS "Receiver Un Squelch" is available in that radio. You have to unsolder the shield to get to it.

  Well, it is a generic question - any radio without COR. The specific model in my case is a UHF radio module model # SA-828U: http://www.alibaba.com/product-detail/1W-5km-distance-SA828-U-uhf_60092524887.html?spm=a2700.7724857.29.62.Xbg6c5    Steven Donegan

   Does anyone have a circuit that will take audio from a radio and generate a pseudo COR signal for the  URI-x? If so would you share the circuit diagram?
