Hello I was wondering why I cannot receieve 482.5125 as great as 471.6500? This really bothers me as I know both systems are in same location. Is there a problem with this particular system. Also I am located in new bedford mass which is southern Bristol county mass. Also in comparison I can get Plymouth police intercity and I can get bapern crystal clear on 470.7875 and 470.5625 like these are right next door to me?
