Hello, I saw the post was titled Topaz regional. I'm a photojournalist that relies on a scanner for my Mesa based work, Mesa PD still seems like they're on the older, non-digital system? I have been successful at listening to communications at my base, then being able to respond to events that are happening in Mesa, by taking my current device on the move and continuing without interruption to monitor communications.. I also work in Scottsdale but that system seems different, P25 Phase II perhaps? I'd love to find a scanner or pager that will allow me to listen to things happening at a static base then be able to grab the device and go mobile while still maintaining good listening. Is there a good device out there that will allow this? I hear about how the nicer Unidens have problems with people at a home location wanting to transfer to mobile movement? I hear the praises of the Unication G5... will this or any device allow me to listen reliably to City of Mesa PD and Scottsdale PD, not at the same time, then take the device and move to other locations in the city while receiving transmissions?
