Hi, I am looking to buy a newer base type scanner that performs best on the 150 and 450 mhz bands. I monitor ems, police, ham and commercial services. There is very little P25 activity in my area. I use a Tram 1481 roof mounted antenna on my RS Pro2050 and get good coverage, but I think it is time to upgrade. I use the computer to program ham equipment, so I am willing to give scanners a try also. Jim
