Has anyone had issues with the Pro-405 getting out of tune in the 450 mhz range? I am trying to monitor a frequency (453.600) and am having to use 453.6125 to hear the frequencly clearer. Also, how would you retune the scanner?

Assuming you have determined it is the scanner and not the system you are listening to it would require test equipment to generate and measure various frequencies and the manufacturers detailed service instructions on what to adjust and where the adjustment is located within the scanner. And a lot of experience to not screw up the scanner while doing the alignment. However if it is off frequency due to components that have changed value it would require replacing surface mount components and doing an alignment of the scanner. And a whole lot more experience in knowing what components to replace.
