I have done a lot of google searches but this is just beyond me and a little frustrating. I run a website for security officers. I have been using the iphone app police scanner but now comes the time for a upgrade. What is a good handheld police scanner that will work with the Memphis police frequencies. I see things about trunks, digital, P25? I would like to spend no more then 300. Just something that works and can use it to update website when needed.
