I have found a local entity using Motorola cp150's . I am trying to search for the frequency that they are using. Are these radios pre-set with frequencies? I'm not even sure if they are using uhf or vhf at this point. I see that the cp150 is capable of using the 146-174 range as well as 438-470 range. Can I narrow the search fields somehow to ease the search process as in removing the Amateur ranges and others?Thanks for any help..........................
